Best way for unit testing in meteor app
AngularJS - Mocking service functions. Undefined from Jasmine test
I'm having problems. I am using AngularJS v1.4.8 with Angular-Mocks and lodash. I have created a bare-bones simple AngularJS app that simply takes an object and adds onto it.
I would like to know how to mock an AngularJS service and its (instantiated) functions.
Here is my app/main/main.js controller:
'use strict';
angular.module('main', [
'testapp.models.main'
])
.config(function ($stateProvider) {
$stateProvider
.state('testapp.main', {
url: '/',
views: {
'mainview@': {
controller: 'MainCtrl as mainCtrl',
templateUrl: 'app/main/main.template.html'
}
}
});
})
.controller('MainCtrl', function MainCtrl($scope, MainModel){
this.addItem = MainModel.addItem;
this.listItems = MainModel.listItems();
});
and here is its model of app/models/main-model.js:
angular.module('testapp.models.main', [])
.service('MainModel', function () {
var items = [
{ 'id': 0, 'label': 'Item No. 1'},
{ 'id': 1, 'label': 'Item No. 2'},
{ 'id': 2, 'label': 'Item No. 3'},
{ 'id': 3, 'label': 'Item No. 4'}
];
this.listItems = function() {
return items;
};
this.addItem = function(label) {
var newID = (Object.keys(items).length);
var theLabel = label ? label : _.random(10000, 1000000);
items[newID] = {'id': newID, 'label': 'Item No. ' + theLabel };
}
});
and here is my karma.conf.js:
module.exports = function(config) {
config.set({
basePath: '../',
frameworks: ['jasmine'],
files: [
// Vendor Files
'bower_components/angular/angular.js',
'bower_components/angular-mocks/angular-mocks.js',
'bower_components/angular-ui-router/release/angular-ui-router.js',
'bower_components/lodash/lodash.min.js',
'bower_components/sinon-1.17.2/index.js',
// App-Specific Files
'app/index.js',
'app/models/*.js',
'app/main/*.js',
// Test-Specific Files
'tests/mock/**/*.js'
],
exclude: [],
reporters: ['progress'],
port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: false,
browsers: ['PhantomJS'],
singleRun: true,
concurrency: Infinity
})
};
and last not but not least, my mock file tests/mock/controllers/MainMock.js: (where I'm having the problem)
describe('Main Mock Unit Tests', function() {
'use strict';
beforeEach(module('ui.router'));
beforeEach(module('main'));
var MainCtrl,
scope;
var mocklistResource;
beforeEach(function() {
mocklistResource = sinon.stub({listItems: function() {}});
module(function($provide) {
$provide.value('main', mocklistResource);
})
});
beforeEach(inject(function ($rootScope, $controller, $state) {
scope = $rootScope.$new();
MainCtrl = $controller('MainCtrl', {
$scope: scope,
$state: $state
});
scope.$digest();
}));
it('Items object to be 4 (default length)', function () {
expect(Object.keys(MainCtrl.listItems).length).toBe(4);
}); // passes
it('should equal the mock list item object', inject(function() {
expect(mocklistResource.listItems[0]).toEqual('Item No. 1');
}))
});
The error comes from the MainMock.js file on the second (and last) it function, gives me:
Expected undefined to equal 'Item No. 1'.
I am trying to get the mocked function of getting the list objects and should return as Item No. 1 successfully but I am getting undefined.
What am I doing wrong? How do I mock this service test? (If there's a better way to do mock tests without sinon, then please let me know.)
Robolectric with third party libraries
My project include several third party libraries like crashlytics, facebook sdk and so on. Some of them require to do initialization on activity startup, however under gradle unit test it will fails, how to avoid this? mocking or use a runtime flag to bypass it?
sdn 4.0 wired behaviour in unit test
This is bit strange for me. I have a company repository
@Repository
public interface CompanyRepository extends GraphRepository<Company> {
Company findByName(String name);
@Query("MATCH (n:Company) WHERE lower(n.name) CONTAINS lower({0}) RETURN n")
List<Company> findByPartialName(String name);
then I have a unit test class to test those two methods
public class CompanyRepositoryTest extends Neo4JTestConfig {
@Autowired
private CompanyRepository companyRepository;
@Before
public void setUp() throws Exception {
Company company = new Company();
company.setName("Westpac");
company.setUrl("www.westpac.com.au");
companyRepository.save(company);
Company company2 = new Company();
company2.setName("test Hl");
company2.setUrl("www.test.com.au");
companyRepository.save(company2);
}
@After
public void tearDown() throws Exception {
companyRepository.deleteAll();
}
@Test
public void testFindByName() throws Exception {
Company company = companyRepository.findByName("Westpac");
assertEquals(company.getUrl(), "www.westpac.com.au");
}
@Test
public void testFindByPartialName() throws Exception {
List<Company> companies = companyRepository.findByPartialName("St");
assertEquals(2, companies.size());
List<Company> companies2 = companyRepository.findByPartialName("west");
assertEquals(1, companies2.size());
}
}
those are looks all good? yep, I think so. I can run each @Test method with out any problems.
However, when I run the on the class level, whatever the 2nd test method always failed.
I looked into the database, the 1st time run @Before, it is all good, two Company are saved into neo4j with the name and url properties. But for the 2nd time run of @Before, all the Company node in neo4j does not have any properties. This is causing the 2nd @Test failed.
I am using
<spring.data.neo4j.version>4.0.0.RELEASE</spring.data.neo4j.version>
and
<neo4j.ogm.version>1.1.2</neo4j.ogm.version>
any idea why?
Android PointF constructor not working in JUnit test
I have just stumbled on this while trying to write a JUnit test. Admittedly this is my first unit test in JUnit, but I do find the behaviour very puzzling.
package com.example.dom.pointfbugrepro;
import android.graphics.PointF;
import org.junit.Test;
import static org.junit.Assert.*;
public class ExampleUnitTest {
@Test
public void pointf_isCorrect() throws Exception {
PointF foo = new PointF(5, 0);
assertEquals(5, foo.x, 0.0001f);
}
}
Running this test in a brand new Android Project results in an assertion failure:
java.lang.AssertionError:
Expected :5.0
Actual :0.0
One thing I found out while investigating this problem is that assigning to the PointF instance's x field directly does work.
So what is the problem here? Why doesn't the constructor set the fields properly? and how should I be testing classes which use the PointF Android class?
Can someone tell me why there is difference between System.out.println() and System.out.print("\n")?
Recently I am doing the project of my software testing course. Today, when I am doing the Junit test to one of the functions in the test code, I come across this question. My test code is about the binary search tree, this unit test is testing its printTree function. When I create a new tree and use the function to print it out, I want to convert it to String so that I can use assertEquals to compare the output with the desired value.
public class TestofPrintTree {
private final ByteArrayOutputStream outContent = new ByteArrayOutputStream();
@Before
public void setUpStreams() {
System.setOut(new PrintStream(outContent));
}
@After
public void cleanUpStreams() {
System.setOut(null);
}
@Test
public void testPrintTree() {
BinarySearchTree t = new BinarySearchTree( );
t.printTree( );
assertEquals("Empty tree\n", outContent.toString());
}
and in the printTree()
public void printTree( )
{
if( isEmpty( ) )
System.out.println( "Empty tree" );
else
printTree( root );
}
The problem is that the failure trace told me that the comparison failed. However, when I click to open the failure trace, the desired value and real value, they are exactly the same. The only difference is here
Can someone tell me what is the difference between System.out.println() and System.out.print("\n") in the question I come across?
Controller test for update, show and destroy does't work for referenced class
I have the "users" and the "empresas", i used the scaffold command to generate the initial CRUD for "empresas" and after that i put the users id into the empresas and all the model need to, so what i want is to just the users that are the owner of the empresa can have acess to the "show", "update" and "destroy", i have a correct_user function and before action to apply that on the actions, everything works fine, unless the tests, i just apply the login into the original scaffold tests.

Symfony web test case JSON
How can I run a webtestcase agains an API? The default guide regarding functional tests only give the following command:
$client = static::createClient();
$crawler = $client->request('GET', '/some-url');
The Crawler class is a DOM crawler. I checked the reference for the FrameworkBundle\Client class and I couldn't find a method that will allow me to make a request that returns raw Response. At least that way, I will be able to json_decode the output and do my tests.
What can I use to achieve this?
Mock WCF service for another instance
There are two solutions: Web and Server that communicate with wcf services. Another solution is Test where I'm writing UI tests. In this Test solution I have Host project where I have service references to Server solution. Then I just implement fake services from interfaces of referenced services. And depending on build configuration Web use link to fake host from config. So in this way I've separated Web testing from server side, and another benefit it's speed. In the test I need, for example, verify that method was called with appropriate parameters and return something back when I press the button. So in the implementation of the fake method I need to log all parameters and return some information that depends from these parameters. But I'm trying to find another way how to mock it, for example how it looks with Rhino mocks. And test can looks something like this.
Page.PressAddCustomerButton();
mock.Expect(t => t.AddCustomer("Name", "Surname")).Return(response.Ok);
Could you please help me. Is it possible?
Unit testing static methods using moq issue
I am having trouble understanding why there is discrepancy between these two tests.
First, Test A:
Public Sub GetTypes_Success()
_context = New Mock(Of IFraternalEntities)()
_cacheProvider = New Mock(Of ICacheProvider)()
Dim type1 = EntityCreator.Create(Of SomeType)()
Dim type2 = EntityCreator.Create(Of SomeType)()
Dim listOfTypes = New List(Of SomeType)({type1, type2})
_context.Setup(Function(r) r.SomeTypes).Returns(QueryableMockSet(Of SomeType).Create(listOfTypes.AsQueryable()).Object)
_repo = New TypeRepo(_context.Object, _cacheProvider.Object)
Dim results = _repo.GetSomeTypes()
Assert.AreEqual(listOfTypes.Count, results.Count, "Not all types returned")
End Sub
testing the method
Public Function GetSomeTypes() As IEnumerable(Of DTO.SomeType) Implements ITypeRepo.GetSomeTypes
Dim results = Entities.SomeTypes.OrderBy(Function(x) x.SortOrder).AsEnumerable()
Return results.Select(Function(x) New DTO.SomeType With {
.TypeID = x.TypeID,
.Name = x.Name,
.Description = x.Description
})
End Function
This test works perfectly. However, I have a dang near equal test here, Test B:
Public Sub GetSecondaryTypes_Success()
_context = New Mock(Of IFraternalEntities)()
_cacheProvider = New Mock(Of ICacheProvider)()
Dim type1 = EntityCreator.Create(Of OtherType)()
Dim type2 = EntityCreator.Create(Of OtherType)()
Dim listOfOtherTypes = New List(Of OtherTypes)({type1, type2})
_context.Setup(Function(r) r.OtherTypes).Returns(QueryableMockSet(Of OtherType).Create(listOfOtherTypes.AsQueryable()).Object)
_repo = New TypeRepo(_context.Object, _cacheProvider.Object)
Dim results = _repo.GetOtherTypes()
Assert.AreEqual(listOfOtherTypes.Count, results.Count, "Not all types returned")
End Sub
Testing this method
Public Function GetOtherTypes() As IEnumerable(Of DTO.OtherType) Implements ITypeRepo.GetOtherTypes
Dim results = Entities.OtherTypes.AsEnumerable()
Return results.Select(Function(x) x.MapToDTO())
End Function
with the MapToDTO() looking like this:
<Extension>
Function MapToDTO(entity As NaturalDisaster) As DTO.NaturalDisaster
Dim dto = New DTO.NaturalDisaster With {
.TypeID= entity.TypeID,
''lots of other properties here
}
Return dto
End Function
I understand that the Select causes the error NotSupportedException: expression references a method that does not belong to the mocked object. I also understand that doing
_context.setup(function(r) r.OtherTypes.AsEnumerable()).Returns(''this stuff here)
does not work because at this point we are dealing with a linq query. Can someone give me some insight on to why the first method works but the second method does not?
In advance, I may have made an error when transcribing my code onto here, so if it is a syntax error I will correct it.
Thanks
How would I perform property-based testing on a card game's Deal function?
I am studying property-based testing and am curious how I would apply this type of testing to a BlackJack game's Deal function.
Here's a unit test (aka: Example-based test):
[<Test>]
let ``deal two cards`` () =
let hand = 2
let dealPlayer cardCount =
[for i in [1..cardCount] -> shuffleDeck.Pop]
|> Seq.toList
(dealPlayer hand).Length |> should equal (2)
What would be an example of a property-based test?
-
Would I test that the two cards are within a range of 4 suits? (i.e. Spades, Diamonds, Hearts, Clubs) Wouldn't relying on a static type already ensure that for me?
-
Would I test that the two cards are within the range of numbers or faces? (i.e. 2..10;Jack;Queen;King;Ace) Again, wouldn't relying on a static type already ensure that for me?
Again, what should I consider when performing property-based tests for a blackjack game?
Shimmed method not used by test in Release mode
Within Visual Studio 2015 I have a test project to which I've added a fakes assembly.
In the unit test itself I create a shim for a static generic method that returns an instance to the generic type, such as:
using (ShimsContext.Create())
{
ShimStaticClass.TheMethod<MyType>(() => instanceOfMyType);
// ... code that uses StaticClass.TheMethod here ...
}
When the solution is built in debug mode the test runs fine and passes. However, when the solution is built in release mode the shimmed version of TheMethod does not get called, which is causing the test to fail.
I know that the shimmed method is not called because I've changed it to throw an exception by doing:
using (ShimsContext.Create())
{
ShimForStaticClass.TheMethod<MyType>(() =>
{
throw new InvalidOperationException("Shim was called");
});
// ... code that uses StaticClass.TheMethod here ...
}
and this exception is not thrown.
I've turned on diagnostic logging and noisy verbosity for the fake but the build logs do not indicate any issues.
Running Web Component Tester Locally
Do I have to install Web Component Tester (wct) globally? E.g. npm install -g web-component-tester. Is there any way to install it as a local module? E.g. npm install web-component-tester. If so, how do I execute it?
Write test method for MVVM- Ninject DI - Entity Framework
I'm learning to write test method. But I still don't know how to created fake data for the test class.
Here's my code:
public interface IData
{
Staff GetUser(string username, string password);
}
// Implement class , which get data from a DataContext
public class EFData: IData
{
HotelDataContext dataContext;
public Staff GetUser(string username, string password)
{
var staff = dataContext.Staffs.Where(s => s.Username == username && s.Password == password).FirstOrDefault();
return staff;
}
}
// My ViewModel which I want to test
public class StaffViewModel: INotifyPropertyChanged
{
IData _data;
// I use Ninject for Dependency Injection here
public StaffViewModel(IData data)
{
_data = data;
}
// I want to test this method
public bool Login(string username, string password)
{
var staff = _data.GetUser(username, password);
return (null != staff);
}
}
As I know, now I need to write some class like this , but I have no idea how to create the test data for this method.
[TestClass]
public class StaffVMTest
{
[TestMethod]
public void TestLogin()
{
////
// wrong_test_username, pw ; success_test_username, pw = ????
////
var testResult1 = vm.Login(wrong_test_username, wrong_test_pw);
var testResult2 = vm.Login(success_test_username, success_test_pw);
Assert.AreEqual(false, testResult1);
Assert.AreEqual(true, testResult2);
}
}
Salesforce Trigger Test Error
Hello!
I am working on unit tests for trigger within Salesforce and I keep encountering an error that I can't seem to solve so I am hoping someone with more experience can help me get back on track. I've hunted around on Google and messed with the structure of my code many times but I'm unable to find a solution.
Purpose:
I have been tasked with writing a trigger that will handle the logic required to maintain case rankings per developer. Each developer is assigned cases and those cases may or may not have a priority determined by the business. Each developer may only have 10 cases prioritized at any one time. Any other cases will just have a null value in the ranking field. If a case with a ranking is inserted, updated, or deleted then all the other cases assigned to that developer with a rank must automatically update accordingly. Any case with a rank higher than 10 will get nulled out.
Problem:
I have completed the trigger and trigger handler class now I am writing unit tests to cover all the unit tests. When I finished my first unit test method I got an error that referenced a workflow issue. I found and corrected the issue but after I finished my second unit test method I get the same error again. I can comment out either of the two methods and the other passes but whenever I run them together I get a pass on the first and a fail on the second with the same original error.

Mock a "blocking" method call with Spock?
Background
I'm learning to use Spock for unit testing and I've come across an issue I can't seem to get my head around:
Note: This example is very simplified, but it gets the idea of what I'd like to achieve across.
I have a class (call it Listener) which accepts a java.net.ServerSocket as a constructor parameter; it has a startListening method, which spawns a new thread which does the following (heavily reduced for brevity):
while(listening) {
try {
Socket socket = serverSocket.accept();
doSomethingWithSocket(socket);
} catch(IOException ex) {
ex.printStackTrace();
listening = false;
}
}
In normal operation, the serverSocket.accept() call blocks until a connection is made to the ServerSocket.
Problem
I'd like to be able to test the interactions on the Socket returned by serverSocket.accept(). I can do this with Spock in the following way:
given: "A ServerSocket, Socket, and Listener"
def serverSocket = Mock(ServerSocket)
def socket = Mock(Socket)
serverSocket.accept() >> socket
def listener = new Listener(serverSocket)
when: "Listener begins listening"
listener.startListening()
then: "Something should be done with the socket"
// Verify some behavior on socket
At first glance, this works fine, except that every call to serverSocket.accept() will return the mocked Socket. Since this call is (intentionally) being invoked an indefinite number of times (because I want to accept an indefinite number of inbound connections) all of the interactions on the mock Socket occur an indefinite number of times (depending on how fast the machine is, how long it takes to run, etc...)
Using cardinality
I could use the cardinality of the interaction to specify at least one interaction, like so:
1.._ * socket.someMethod()
But something about that rubs me the wrong way; I'm not really looking for at least one interaction, I'm really looking for one interaction.
Returning null
I could do something like this (to return the Mocked socket once and then null):
serverSocket.accept() >>> [socket, null]
But then I still have tons of calls to doSomethingWithSocket that pass a null parameter, which I then have to check for and ignore (or report). If I ignore it, I might miss reporting a legitimate issue (I don't think ServerSocket#accept can ever return null, but since the class isn't final maybe someone implements their own version which can) but if I report it, my test logs get polluted with the log message that's reporting an expected outcome as an unexpected one.
Using closures and side-effects
I'm admittedly not a Groovy programmer by trade and this is the first time I've worked with Spock, so my apologies if this is a just plain wrong thing to do or if I'm misunderstanding something about how Spock does mocking
I tried this:
serverSocket.accept() >> socket >> {while(true) {}; null }
This loops forever before the accept method is even called; I'm not 100% sure why, as I didn't think the closure would be evaluated until the accept method was called a second time?
I also tried this:
serverSocket.accept() >>> [socket, { while(true){}; null }]
It's my understanding that when the accept method is called the first time, socket will be returned. Further calls will invoke the closure, which loops infinitely and should therefore block.
Locally, this appears to work, but when the build is run by a CI service (specifically, Travis CI) I still see test output indicating that the accept method is retuning null, which is a little bit confusing.
Am I just trying to do something that can't be done? This isn't a deal breaker for me or anything (I can live with noisy test logs) but I'd really like to know if this is possible.
Mockito: using a method in "thenReturn" to return a mock doesn't work
I have encountered what I assume might be a bug with Mockito, but was wondering if anyone else can shed light as to why this test doesn't work.
The full example class is here on pastebin, but I'm going to walk through it.
Basically, I have two objects, like this:
public class FirstObject {
private SecondObject secondObject;
public SecondObject getSecondObject() { return secondObject; }
}
public class SecondObject {
private String name;
public String getName() { return name; }
}
The first object is mocked via annotation and the before method:
@Mock
FirstObject mockedFirstObject;
@Before
public void setup() {
MockitoAnnotations.initMocks(this);
}
The second object is mocked in a method:
public SecondObject setupMockedSecondObject() {
SecondObject secondObject = Mockito.mock(SecondObject.class);
Mockito.when(secondObject.getName()).thenReturn("MockObject");
return secondObject;
}
When "thenReturn" contains a direct call to this method to setup and obtain a mock of the second object, it fails:
@Test
public void notWorkingTest() {
Mockito.when(mockedFirstObject.getSecondObject()).thenReturn(setupMockedSecondObject());
Assert.assertEquals(mockedFirstObject.getSecondObject().getName(), "MockObject");
}
But when the mock returned by the same method is assigned to a local variable, which is used in "thenReturn", it works:
@Test
public void workingTest() {
SecondObject mockedSecondObject = setupMockedSecondObject();
Mockito.when(mockedFirstObject.getSecondObject()).thenReturn(mockedSecondObject);
Assert.assertEquals(mockedFirstObject.getSecondObject().getName(), "MockObject");
}
Are we doing something wrong... or is this indeed a bug/limitation in Mockito? Is there a deliberate reason for this not working?
How do I add to the MediaStore for testing with Robolectric
My goal is to test some Android App code that gets a list of image files that are on the device and then does some work on that list.
I am new to Android and Android Unit testing.
I am attempting to add images to the MediaStore within a Robolectric unit test, but I am not sure how to proceed.
These are the steps I think I need to perform:
- Add the Test Images to a known directory on the local system.
- Copy the images to the Robolectric Temp directory that the Media Service will expect or can be pointed to.
-
Then run insertImage and add the images to the MediaStore.
MediaStore.Images.Media.insertImage(...);
When I attempt to insert the image however the method returns null.
I have images, but I am not sure where to copy them for the MediaStore to understand, and I am not sure why when I run the insertImage on a known image path I get a null return. I am not longer getting a FileNotFound exception so I believe it is finding the file.
Python 2.7 - Mutation Testing Tool suggestions
I have a system, whose modules are written in Python 2.7 and I'm given the task of proceeding with a mutation testing of some of the modules. I've done my research on the topic and now I'm getting on the tools. As long as I read, MutPy is considered to be the best (so far) developed tool for this kind of testing. The problem is, though, it is suitable for testing in Python 3.* versions.
Could somebody please help me with ideas for other tools for Python 2.7?
I was also thinking of converting the modules I need from 2.7 to 3.*, but I'm unsure if the system will somehow misbehave.
Any help will be appreciated, thank you.
Python Mocking Out Two File Open Contexts
I am trying to write some unit tests using mock for some code that looks like this:
# Write some text to edit to a file
with tempfile.NamedTemporaryFile(delete=False) as tf:
tfName = tf.name
tf.write(text_to_edit)
# Edit the text with vim
edit_file(tfName)
# Read edited text
with open(tfName, 'r') as f:
text = f.read()
# Delete the file
os.remove(tfName)
# ... do stuff with text ...
This was my initial attempt at creating mock objects for that code:
@pytest.fixture
def mock_tempfile(mocker):
new_tfile_obj = mock.MagicMock()
tfile_instance = mock.MagicMock()
tfile_instance.name.return_value = 'mockTemporaryFile'
mocker.patch('tempfile.NamedTemporaryFile', new_tfile_obj)
new_open = mock.MagicMock()
fake_file = mock.MagicMock(spec=file)
new_open.return_value = fake_file
new_tfile_obj.return_value = tfile_instance
mocker.patch('__builtin__.open', new_open)
return (new_tfile_obj, tfile_instance, new_open, fake_file)
# ... Code to mock edit_file/modify the temp file are in the actual test ...
However, I don't expect that to be anywhere near what should be used. I'm totally lost on how I would mock something like that.
Android Unit testing with AsyncTask
Hey everyone just getting started with Android testing and I am trying to test an async task. Here is the async task code. I am following this SO post Android AsyncTask testing with Android Test Framework. The runTestOnUiThread is not found in AndroidTestCase however. If I understand this correctly if its not run on the ui thread then the test finishes before the async task completes? Any help is greatly appreciated !
public class BackendTest extends AndroidTestCase {
private static MyApi myApiService = null;
private Context context;
public void testAsyncJoke () throws Throwable{
// create a signal to let us know when our task is done.
final CountDownLatch signal = new CountDownLatch(1);
final AsyncTask<Pair<Context, String>, Void, String> myTask = new AsyncTask<Pair<Context, String>, Void, String>() {
@Override
protected String doInBackground(Pair<Context, String>... params) {
if(myApiService == null) { // Only do this once
MyApi.Builder builder = new MyApi.Builder(AndroidHttp.newCompatibleTransport(), new AndroidJsonFactory(), null)
.setRootUrl("http://ift.tt/1To3LcZ");
myApiService = builder.build();
}
context = params[0].first;
String name = params[0].second;
try {
return myApiService.sayHi(name).execute().getData();
} catch (IOException e) {
return e.getMessage();
}
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
signal.countDown();
}
};
// Execute the async task on the UI thread! THIS IS KEY!
runTestOnUiThread(new Runnable() {
@Override
public void run() {
myTask.execute("Do something");
}
});
signal.await(30, TimeUnit.SECONDS);
// The task is done, and now you can assert some things!
assertTrue("Happiness", true);
}
}

@Inject
@Config(value = "endpoint.base", defaultValue = "http://localhost:52885/consumers")
private String base;
public String getBase() { return base; }
}
this object is injected to a service object like this:
public class LoyaltyService {
final Sender sender;
final Configuration config;
@Inject
public LoyaltyService(Sender sender, Configuration config) {
this.sender = sender;
this.config = config;
}
}
I am now testing this service object with Mockito. I want to mock the Sender object, but I don't want to mock the configuration, or at least I just want to use the default value defined inside the object.
How can I do that in a Test object?
For example, I tried the following:
public class LoyaltyServiceTest {
@Mock
private Sender sender;
@Inject
private Configuration config;
private LoyaltyService target;
@Before
public void init() {
MockitoAnnotations.initMocks(this);
when (sender.post(anyString(), anyString())).thenReturn("Post Success");
target =new LoyaltyService(sender, config);
}
}
It doesn't seem CDI will register the Config object at all. How does this work? Thanks!
UIViewController lifecycle of topViewController in a UINavigationController not being simulated by beginAppearanceTransition:animated:
I'm writing unit tests for a bunch of view controllers hooked up with segues in a storyboard. The initial view controller is a UINavigationController.
I was interested in testing that a button in the topViewController, once tapped, performed some action (e.g. it invoked a method on a mock, for instance).
This requires the UINavigationController and its children to be loaded into the view hierarchy first.
I learned from at least two sources that you can call the viewController's beginAppearanceTransition:animated: is recommended by both:
The trouble is, when you invoke beginAppearanceTransition:animated: on a UINavigationController, the lifecycle methods (viewDidLoad, viewWillAppear:, viewDidAppear: etc.) don't get invoked for the topViewController.
That's really strange, because you'd think that loading the view of the navigation controller would necessarily require the top view controller to be loaded as well.
What can be done about this? My current workaround is just to load the view of the top view controller directly; but this is not ideal.
Async xUnit async unit tests are not visible
I use Visual Studio 2015 Ultimate, I wrote some unit test (I use xUnit 2.1.0.3179, it allow for this signature):
public async Task MyTest()
instead of standard unit test signature
public void MyTest()
but these unit tests are not visible in Visual Studio (code lens) and in Test Explorer. Of course I rebuild solution without any error :)
Is there any possibility to have the same feature like tests with standard signature? Maybe there is any VS extension?
Specta 'should receive' code
I'm trying to use Specta as my unit testing framework (Instead of Kiwi). How can I test if an object receives a selector Let's say 5 times, like I do in Kiwi?
In other words, what is the equivalent to this 'Kiwi' line of code:
[[sut should] receive:@selector(showUpsellIfNeededForFile) withCount:5];
Thanks in advance.
How to read grouped records in XamDataGrid when grouping is set programatically in tests?
I'm trying to write some test scenarios for the XamDataGrid. In these scenarios I'd like to set the grouping on a single Field. This code causes the grid to group as expected when I run the app and double-click the grid:
Private Sub MyGrid_MouseDoubleClick(sender As Object, e As MouseButtonEventArgs) Handles MyGrid.MouseDoubleClick
Dim xamDataGrid As XamDataGrid = CType(sender, XamDataGrid)
Dim field As Field = xamDataGrid.FieldLayouts(0).Fields("A")
Dim fieldSortDescription As New FieldSortDescription With {.Field = field, .Direction = ListSortDirection.Ascending, .IsGroupBy = True}
xamDataGrid.FieldLayouts(0).SortedFields.Add(fieldSortDescription)
End Sub
In tests, after running something very similar the Records and ViewableRecords collections do not reflect the grouping. xamDataGrid.ViewableRecords(0) is a DataRecord and not a GroupByRecord. Here's the code from the test:
<TestMethod()>
Public Sub Test()
Dim xamDataGrid As New XamDataGrid
xamDataGrid.DataSource = dataSource.DefaultView
xamDataGrid.BeginInit()
xamDataGrid.EndInit()
Dim field As Field = xamDataGrid.FieldLayouts(0).Fields("A")
Dim fieldSortDescription As New FieldSortDescription With {.Field = field, .Direction = ListSortDirection.Ascending, .IsGroupBy = True}
xamDataGrid.FieldLayouts(0).SortedFields.Add(fieldSortDescription)
' exception thrown here because xamDataGrid.ViewableRecords(0) is a DataRecord
Dim groupByRecord As GroupByRecord = CType(xamDataGrid.ViewableRecords(0), GroupByRecord)
' ...
End Sub
How can the grid be refreshed or otherwise forced to reflect the grouping set by the code?
Thanks for your time.
Test Failed - Failed to set up the execution context to run the test
I am attempting to write unit tests for a set of classes that access or modify global variables.
The first global I needed to wrap up was:
extern std::atomic<Foo> GlobalFoo;
Where Foo is an enum class. I wrote 2 separate classes to handle the setting and getting of the value. I constructed unit tests that passed as expected. Within the test files I include variables to copy the global state (plus extra stateless objects that I may use for testing). I can then use these global copies for restoring values after each test. For example:
namespace Tests
{
// Global save state
const Framework::Foo originalGlobal = Framework::GlobalFoo;
// Test constants
const auto service = Framework::FooRetriever();
const auto testFoo = Framework::Foo::SomeValue;
TEST_CLASS(FooRetrieverUnitTests)
{
...
The next global I started working on was:
extern const std::unordered_map<
std::vector<char>, std::vector<char>, std::hash<std::vector<char>> GlobalBar;
I want to construct a class that is going to return a shared pointer to this global collection.
I start off by writing my test constants:
namespace Tests
{
// Alias
using Collection = const std::unordered_map<
std::vector<char>, std::vector<char>, std::hash<std::vector<char>>;
// Global state
const std::shared_ptr<Collection> global =
std::make_shared<Collection>(Framework::GlobalBar);
TEST_CLASS(FooRetrieverUnitTests)
{
// TODO
};
}
However, running the test at this point produced the following message for all my tests (i.e. not just this new test):
Failed to set up the execution context to run the test
Commenting out the global allows all tests to run.
If I move the line commented as // Global state into a test method then the test will run without problem.
I looked into the error, but could not find anything that applied to my problem. I suspect the error message is masking the real problem. When I run the tests via command line I do not get any extra information. I was led to believe that it was possibly due to a missing DLL (although I found that hard to believe, seeing as I was merely using the standard library with no extras).
My project is a static library, and my unit tests are in the form of a DLL (this is the default approach used by Microsoft Visual Studio's unit testing framework).
Minus the usual "don't use globals" rant, I was wondering if anyone could provide some insight into the problem I am encountering. Perhaps I am doing something wrong by making a copy of the global collection in my Tests namespace or there is another bug in Visual Studio's unit testing feature.
The code compiles without error or warnings but the unit tests will not run in this state.

Unit testing directives with nested dependencies
I am an angularJS beginner and I am trying to unit test a directive that has nested dependencies, I have tried different things but the service is always undefined. How do i go about this, I have given the structure of my code below.
app.directive('directive1', function($compile, service1){
return {
restrict : 'EA',
templateURL: 'directive1.html',
scope: {
},
link: function(scope, element, rootScope){
},
controller: function($scope, $element,$rootScope){

});
First service
apps.factory('service1', function($q, $http, service2){
}
second service
apps.factory('service2', function($q, $http, service3){

How to specify a relative date in yaml fixtures for RoR unit tests
I'm writing unit test using fixtures in yaml for a ruby on rails project.
We have many tests for users being < or > to n year old. ex:
young_kid:
id: 2
firstname: Nano
lastname: Shinonome
email: imarobot@nichijou.jp
birthdate: 2000-05-11
Is there a way to specify a relative date like 2.days.from_now So that our tests are not bound to fail once the threshold is reached ?
We're using vanilla RoR unit tests.
Rspec: testing cancan ability with arguments
I am using cancan gem.
I have ability defined in my class:
module Gexcore
class Myability
include CanCan::Ability
def initialize(user)
can :delete_user, User do |victim|
..
end
end
end
end
I am testing the ability to delete user with RSpec:
RSpec.describe "Permissions to delete user", :type => :request do
describe 'del user' do
it 'superadmin can delete user' do
superadmin = double(User, :id => 10, <<some other fields>>)
ability = Mymodule::Myability.new(superadmin)
victim = double(User)
res = superadmin_ability.can?(:user_del, victim)
expect(res).to eq true
end
end
end
My user model: class User < ActiveRecord::Base delegate :can?, :cannot?, :to => :ability ... end
But it doesn't see method can? :delete_user, User from my ability. It expects User class but RSpec calls it with RSpec::Mocks::Double class.
How to test correctly ability from cancan gem using Rspec mocks ?
How to test private method using PowerMock which has object creation?

VC++ unit test project failed to set up the execution context to run the test due to possible missing dll
VC++ Newbie here:
I am attempting to TDD a project that uses a third party library (specifically AutoDesk's ObjectARX).
I have been able to create a dummy solution with a unittest project and a helloworld ARX project. I can successfully test a dummy method, everything is cool.
But when I call anything from the ObjectARX libraries the unit tests fail with
Failed to set up the execution context to run the test
After digging about and using Dependency Walker I found that the compiled dll is not able to find acdb21.dll which is named the same as one of the ARX libraries. It's expecting to find it in the same folder as the compiled dll.
I do not have an acdb21.dll, only the .h and .lib files. My understanding is that they should be compiled into the dll.
The linker happily finds the .h and .lib files so AFAICT the include and library paths are all set correctly.
Is the missing dll reported by Dependency Walker a red herring? Is something else amiss?

MOQ dictionary wrapper not returning mocked content
I have a class called CacheHelper that contains a ConcurrentDictionary property. I want to mock the return values. The dictionary itself is also mocked so that it returns an object when the index getter is used. When I call the dictionary directly I get the mocked item. But when I call the CacheHelper to get the same mocked dictionary, and then call the getter on the dictionary a different item is returned. I do not understand why this is. See code below
Guid dataFileId = Guid.NewGuid();
DataFile dataFile = new DataFile() { Id = dataFileId };
var myRepo = new Mock<DataFilesRepository>();
myRepo.Object.DataFiles.Add(dataFile);
var myDict = new Mock<MockConcurrentDictionary<Guid, DataFilesRepository>>();
myDict.SetupGet(x => x[It.IsAny<Guid>()]).Returns(myRepo.Object);
var cacheHelper = new Mock<CacheHelper>();
cacheHelper.Setup(x => x.CacheDataFiles).Returns(myDict.Object);
So when I call myDict.Object[new Guid()] I get the dataFile that I put in the Setup function. When I call cacheHelper.Object.CacheDataFiles[new Guid()] I get the item that is added by default in the MockConcurrentDictionary constructor.
Extra information: I use my own MockConcurrentDictionary to be able to return true when ContainsKey is called on the dictionary. The reason for this is so I can still do my state checks in my unit test. See definition of the MockConcurrentDictionary below.
public class MockConcurrentDictionary<TKey, TValue> : ConcurrentDictionary<TKey, TValue>
{
public MockConcurrentDictionary() : base(new AlwaysTrueEqualityComparer<TKey>())
{
// If we do not add a item to the dictionary then it will not call Equals after a ContainsKey call.
// Our AlwaysTrueEqualityComparer would have no use than.
TKey key = (TKey)Activator.CreateInstance((typeof(TKey)));
TValue value = (TValue)Activator.CreateInstance((typeof(TValue)));
this.TryAdd(key, value);
}
public MockConcurrentDictionary(TValue value) : base(new AlwaysTrueEqualityComparer<TKey>())
{
// If we do not add a item to the dictionary then it will not call Equals after a ContainsKey call.
// Our AlwaysTrueEqualityComparer would have no use than.
TKey key = (TKey)Activator.CreateInstance((typeof(TKey)));
this.TryAdd(key, value);
}
public virtual new TValue this[TKey key]
{
get { return base[key]; }
set { base[key] = value; }
}
}
How to prevent RSpec helper from being loaded
I'm writing integration tests with Capybara at the moment for our Rails 4 application. To make this as light-weight as possible, I have written a capybara_helper.rb file that is located inside the spec folder to be used with RSpec.
However, this file is loaded every time when the RSpec tests are running, destroying the configuration for existing Capybara tests that originally were present inside the test suite.
Is there a way to tell/configure RSpec to not load this file when starting up the "normal" unit tests?
My Integration tests are loaded with the command RAILS_ENV=test bundle exec rspec --tag @type:capybara. Our normal tests are just ran using rake parallel:spec[4]
How to include chutzpah test cases in tests project to output folder
I have a web project, say 'WebProj' in which I have defined all the my javascript source files with angular code. I am defining my chutzpah unit test cases for those javascript source files in another project 'WebProj.Tests' along with my other C# test cases. I am having both the web and tests project under same solution.
My problem is that when I try to integrate the web project to the TFS build process I cannot run the chutzpah test cases as the web project output folder don't have the chutzpah test case files copied to the project output folder. At the same time the test cases are executed if I have the chutzpah test cases defined in the same web project.
How can I execute the javascript chutzpah test cases on build process if those are defined in a separate Test project and include them in project output folder after build?
Angularjs+ jasmine test returns zero length
I'm calling a service in my unit test. The service seems to be available and the method is defined. I've created and spy and when I call the method I'm not receiving errors. When I try to access the response of the service call I get zero length (there are 2 records).
What am I missing?
describe("can I initialise the object ", function () {
var myMethodToCallDataService;
beforeEach(function(){
module(moduleName);
module('services');
inject(function($injector, _$controller_, _$rootScope_){
$controller = _$controller_;
$rootScope = _$rootScope_;
myMethodToCallDataService = $injector.get('myMethodToCallDataService');
});
});
it("myMethodToCallDataService should be defined", function () {
expect(myMethodToCallDataService).toBeDefined();
});
it("myMethodToCallDataService should call the mt", function () {
scope = $rootScope.$new();
spyOn( myMethodToCallDataService, 'myMethodToCall' );
myMethodToCallDataService.myMethodToCall();
expect(myMethodToCallDataService.myMethodToCall).toHaveBeenCalled();
scope.$apply();
expect(myMethodToCallDataService.myMethodToCall.length).toBeGreaterThan(1);
});

angularjs how to call service method inside jasmine unit test
I'm wanting to call a service method inside my jasmine unit test. I've been looking around and there are many ways, it seems to call a method that returns a promise.I'd like to call the service method and read the response back or at least test it. Whats the best way to call the service and get back the response in my unit test?
describe("can I call a service method ", function () {
var getMyservice;
beforeEach(function(){
module(moduleName);
module('myservice.dependency');
inject(function($injector, _$controller_, _$rootScope_){
$controller = _$controller_;
$rootScope = _$rootScope_;
getMyservice = $injector.get('getMyservice');
});
});
it("getMyservice should be defined", function () {
expect(getMyservice).toBeUndefined();
});
});
"Lost connection to test manager service" when running unit tests in Xcode

Error running XUnit tests in VS2013 / ReSharper 8 - xunit.dll not found
I've upgraded all the xUnit NuGet packages in my solution to XUnit 2.1 in the hope of fixing some problems I had running my xUnit tests, but I'm getting the same problem as before, which is:
[Window Title] Unit Test Runner

I've tried un-installing, re-installing, cleaning and rebuilding, etc. etc. for hours and got nowhere.
I'm using Visual Studio 2013 update 5, ReSharper 8.2.1, and have installed the following NuGet packages:

<package id="xunit.runner.visualstudio" version="2.1.0" targetFramework="net451" />
To be fair, there is no file called xunit.dll in the bin folder, but... I've installed everything I can find, and I'm at a loss as to what else I can do.
Suggestions very welcome.
FakeItEasy failed assertion with randomly
I'm trying to implement a unit test with a methodcall assertion. (MustHaveHappened)
I'm using the following code:
[Fact]
public void Should_set_setting_and_map_new_value_for_non_existing_setting()
{
//Arrange
var userSetting = new SettingDetailsBuilder().Build();
var respository = A.Fake<ISettingsRepository>();
A.CallTo(() => respository.GetUserSetting(0, 0, null)).WithAnyArguments().Returns(userSetting);
var dataretriever = new SettingsDataRetriever(respository);
//Act
var newUserSetting = dataretriever.SetUserSetting("variableName", "SomeOtherValue", 1, 1, "FST");
//Assert
A.CallTo(() => respository.GetUserSetting(1, 1, "variableName")).MustHaveHappened();
}
But I get randomly a failed test, whereby some arguments are mentioned as "ignored". However, the assertion is with exact parameters.
Error:
Assertion failed for the following call:
AlfaProNext.Repositories.Settings.ISettingsRepository.GetUserSetting(1, <Ignored>, <Ignored>)
Expected to find it at least once but found it #0 times among the calls:
1: AlfaProNext.Repositories.Settings.ISettingsRepository.Exists(varName: "variableName")
2: AlfaProNext.Repositories.Settings.ISettingsRepository.GetUserSetting(
userId: 1,
profileId: 1,
variableName: "variableName")
Does anybody knows why this is happening randomly?
Skip a method execution to unit test controller flow
public class DemoController : Controller
{
private readonly ICommonOperationsRepository _commonRepo;
public DemoController (ICommonOperationsRepository commonRepo)
{
_commonRepo = commonRepo;
}
public ActionResult Default()
{
var model = new DemoModel();
try
{
**ConcreteClass cc = new ConcreteClass(Request.ServerVariables["HTTP_X_REWRITE_URL"].ToString());
cc.ConcreteClassMethod();**
model.ListTopListing.AddRange(_commonRepo.GetListings());
}
catch (Exception ex)
{
ExceptionHandler objErr = new ExceptionHandler(ex, "DemoController .Default()\n Exception : " + ex.Message);
objErr.LogException();
}
return View(model);
}
}
I am trying to unit test my controller. ConcreteClass constructor and its method ConcreteClassMethod both have some dependency on HttpRequest variables which i am not able to pass from my unit tests.
I want a way by which i can simply skip execution of ConcreteClass's constructor and ConcreteClassMethod when I am calling Default action of DemoController.
Why does Visual Studio use a different output directory for a) normal unit tests and b) data driven unit tests?
At first we only had a couple of data constellations we used to regularly test. Those we tended in the testcode having a couple arrays of data and looping through those to run tests.
Now that we have huge DataSources (namely Excel-Files) that contain 100s of data rows that are to be run through our unit tests we used the VisualStudio.TestTools to configure according DataSources:
<configSections>
<section name="microsoft.visualstudio.testtools"
type="Microsoft.VisualStudio.TestTools.UnitTesting.TestConfigurationSection, Microsoft.VisualStudio.QualityTools.UnitTestFramework, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
</configSections>
<connectionStrings>
<add name="KradTestConnection" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Beitragstests_KRAD_Tarif2016.xls;Extended Properties=Excel 12.0 Xml" providerName="System.Data.OleDb" />
<add name="PkwTestConnection" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Beitragstests_PKW_Tarif2016.xls;Extended Properties=Excel 12.0 Xml" providerName="System.Data.OleDb" />
</connectionStrings>
<microsoft.visualstudio.testtools>
<dataSources>
<add name="KradTestDataSource" connectionString="KradTestConnection" dataTableName="TestInput" dataAccessMethod="Sequential"/>
<add name="PkwTestDataSource" connectionString="PkwTestConnection" dataTableName="TestInput" dataAccessMethod="Sequential"/>
</dataSources>
</microsoft.visualstudio.testtools>
With that we just provided the data files 'Beitragstests_KRAD_Tarif2016.xls' and 'Beitragstests_PKW_Tarif2016.xls' and decorated our testcases with the DeploymentItemAttribute:
[DataSource("PkwTestDataSource")]
[DeploymentItem("Beitragstests_PKW_Tarif2016.xls")]
[TestCategory("DataDriven Berechnungstests")]
[TestMethod]
public void Pkw_HaftplichtMitVollkasko_TestCases() { ... }
So far and only testing those 'data driven unit tests' we had no problems. But our Test-Suite does contain many older testclasses we still require.
If we run data-driven and non-data-driven tests in a seperate test session, everything works out fine and all tests are 'green'.
As soon as we run "ALL" testcases though, many of the non-data-driven tests fail.
Analyzing that behaviour quickly made us aware that - be it mstest or running the tests via resharper (and yes, we disabled 'shadow-copying' in resharper-test-options) - as soon as the data-driven testcases are included in a test session, the tests wont be run in the projects output directory $OutDir that we defined for many projects and solutions (which each deliver a part of the dlls required for our testing suite). Running the data-driven testcases will cause Visual Studio to create a new directory 'TestResults/Deploy_ /Out' located next to the solution file '...sln' instead... in which of course the TestRunner will not find dependent DLLs that are delivered to our $OutDir.
Could anyone please explain to me, why the test engine creates different output directories based on the inclusion of 'data-driven unit tests' into a test session?`
Would anyone have a hint or even a solution about how to get Visual Studio to use the directory $OutDir that we configured in our projects instead of creating a new 'TestResults/Deploy_ /Out' every time?
Thanks in advance!

How to mock GetView operation of couchbase .net SDK
I am trying to write unit test for a method which executes a view on the couch base server using .NET SDK, but unable to mock the o/p.
Method :-
public int CountJsonDocs()
{
int savedFiles = 0;
var viewResult = _couchbaseClient.GetView("GetAllDocs", "GetAllDocuments");
if (viewResult.TotalRows > 0)
{
foreach (var viewRow in viewResult)
{
var jsonData = viewRow.GetItem();
savedFiles++;
}
}
return savedFiles;
}
GetView() method returns an object of type IView
how can I pass argument(s) through nose.run that can be picked up by list of python test files containing test methods
I am creating a series of tests with python unittest and executing them with nosetest module.
I am trying to figure out how do i pass an argument(s), for example environment or domain, so that the value would be passed the actual test method being executed.
I have a runner python script which passes test suite class file and environment as arguments
python runner.py --suite=generic_pass.py --env=dev.domain.com
The runner.py picks up the suite value and passes it to test_suite in nose.run method within "runner.py"
Contents of runner.py
nose.run(argv=["", test_suite, "--verbosity=2"])
The contents of test_suite or "generic_pass.py" script are as follows
class loginTest(login.userLoginTest):
pass
class logoutTest(logout.userLogoutTest):
pass
The contents of login.py
class userLoginTest(unittest.TestCase):
def setUp(self):
self.login = userLogin(user,pass,environment)
def test_response(self):
self.assertEquals(200, getResponse(self.login))
When python runner.py script is executed, it then runs nose.run, which then executes the tests specified in generic_pass.py (test_suite)
I am trying to figure out, how can i pass the contents of --env "dev.domain.com" from runner.py to each test case class file though nose.run() method, so that i could use it in
self.login = userLogin(user,pass,environment)
which is located in login.py
