Xcode: TEST vs DEBUG preprocessor macros

Question

When creating a new project with unit tests, Xcode sets the build configuration to Debug for the Test scheme (same for the Run scheme).

Should I differentiate betwee

Answer 1

Instead of creating a Test build configuration, I:

1. created a Tests-Prefix.pch file:

   #define TEST 1
   #import 
   #import "CocoaPlant-Prefix.pch"
   

2. entered its path in the Prefix Header field of the Tests target's build settings.

3. added the following code to the top of a file I created called MyAppDefines.h, imported in MyApp-Prefix.pch:

   #ifdef TEST
   #define TEST_CLASS NSClassFromString(@"AppDelegateTests") // any test class
   #define BUNDLE [NSBundle bundleForClass:TEST_CLASS]
   #define APP_NAME @"Tests"
   #else
   #define BUNDLE [NSBundle mainBundle]
   #define APP_NAME [[BUNDLE infoDictionary] objectForKey:(NSString *)kCFBundleNameKey]
   #endif
   

This allows me to use BUNDLE where ever I mean [NSBundle mainBundle] and also have it work when I run Tests.

Importing SenTestingKit in Tests-Prefix.pch also speeds up the compiling of the SenTestingKit Framework and allows me to leave out #import from the top of all the tests files.
