Use macro for iOS Unit Test

Question

I am writing test cases for my camera application.

For instance, I want to provide a mock object when the tests are running in Simulator. I could not use macro to run the corresponding code like this:

    #if TARGET_OS_SIMULATOR
    vc.camera = mockCamera
    #endif

What is the better way to do this?

You cannot test if the app is running in test via macro. You can test it in runtime via NSProcessInfo :

[[NSProcessInfo processInfo] environment]["XCInjectBundle"]
