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....

Answer 1

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.
