Answer 1

CACurrentMediaTime is declared at CABase.h and implemented at QuartzCore framework, you'll need to link it to the project.

@Defame Please uncheck the answer if it doesn't solve the problem, if you found another solution you are always welcome to answer yourself and accept it instead. – Shelleyshellfire

And for the persone down-voted the answer, here's the GHUnit source file from the (currently) latest version tag, there you can see import of the QuartzCore header: github.com/gabriel/gh-unit/blob/0.5.6/Classes-iOS/… – Shelleyshellfire

You are correct. The error is due to QuartzCore framework not linked. Let me up vote for you. – Boride

@Defame could you try updating GHunit to the latest version and check if this solution works for you ? It seems to be helpful for other users, let's try to find out what is different for you. – Shelleyshellfire

In our mobile application development course at school, we have been using this tutorial http://www.raywenderlich.com/3716/unit-testing-tutorial-for-ios-xcode-4-quick-start-guide

And It does not Run without the QuartzCore.framework as well, so thank you very much !
