Android unit testing: connectedAndroidTest does not execute my test case

I am trying to add some unit tests to my app. I am developing my app in Android Studio

This is what I did.

• 
  

  Added a new package

  
  


• 
  

  Created a class in new package which extends TestCase

  
  


• 
  

  Added following method to created class

  
  

@SmallTest public void basicTest() { assertEquals("abc", "abc"); }

• Added following to defaultConfig section in build.gradle

testApplicationId "newly.added.package.name" testInstrumentationRunner "android.test.InstrumentationTestRunner"

• Executed following command in Android Studio Terminal

gradlew.bat connectedAndroidTest

But, when I checked the generated html report, it shows that 0 tests were run.

I tried following, but none of them made a difference to the output of gradlew.bat connectedAndroidTest command.

• Added an incorrect package name to testApplicationId in build.gradle.


• Disconnected device

Why doesn't my test case get executed? What have I missed?
