Is there a way to inject test data into a XCTestCase?

I'm trying write some simple test cases for a project I am working on. I have a simple method that takes an input and returns true/false depending on the outcome of an operation on that input. base case unit test right? In java, I can use a framework called TestNG which allows me to inject data into the test so that each data input would be considered a separate test. What I found in Objective-C is that it models something similar to JUnit where something like this isn't possible. What I have to do instead is create an array in setup or somewhere and then loop through the array manually to run the test. This ends up being seen as a single test of X input values, and not X tests of X input values.

Is what I am asking not currently possible in Objective-C? I am using the latest XCode and coding with iOS8.

Thanks in advance! --Michael

my guess is that the XCTesting framework is built up to be exactly like jUnit, meaning than answer to my question is NO. I thought I'd ask in case I am wrong.
