I’m afraid I don’t know anything about GHUnit, I always use SenTesting which ships with XCode.

Hi Drew,
thanks for the useful info. After I changed my setting per your blog , I’m getting new error as
ld: -bundle_loader can only be used with -bundle

1. I’m using XCode 4 and GHUnit.
2. From target project , I’ve created an object of class in main app.
3. From this object I’m trying to call the method in main app.

Can you please help me out with this ?
Also can you please share any sample unit test cases written which I can refer to will be of great help.

Thanks and Regards,
Vikram

Probably obvious, but I wanted to mention that you need to build the simulator version prior to running the unit tests.

You may want to add the app target as a target dependency of the test target. This will enforce that the app target builds first.

Thanks very much! This resolved the aforementioned error that I ran into when adding my first test. The test ran fine when I didn’t reference any of my code but failed as soon as I did (so I think my bundle/framework path was entirely broken, as opposed to compiling twice).

Probably obvious, but I wanted to mention that you need to build the simulator version prior to running the unit tests.

Thanks again!
Owen
