using variables for unit testing only

Question

I am writing unit tests for an app for iPhone using objective c. I want to use some variable only when compiling for test case for example

#ifdef UNIT_TESTING 
@synthesize requestFinished, networkAvailable;//etc
#endif

now where should I define UNIT_TESTING that when I compile for unit tests it should enter this code block.... otherwise should go past it....

Define it in the “Preprocessor Macros” build setting in each of your targets—especially the one where you want that macro defined, the unit test bundle target.

What if the project I want to write unit tests for depends on a static library which I need to use these macros in? The ifdef is never defined since the library is already compiled, no? – Genericrich Apr 08 '11 at 15:39
@Genericrich: Right. You would need to define the macros in the library's target when building the library. If you need to use the macros in both places, put them in a header and import that from the prefix headers of both targets. – Peter Hosey Apr 08 '11 at 19:50
