Alternate AppDelegate for XCTest

alternate_main.m

//I had a need to use a different app delegate in Convene’s XCTest suite today, so I took the time to figure out how to do it.  Quite simple really:

//Switch your main.m to:

@autoreleasepool {
  BOOL runningTests = NSClassFromString(@"XCTestCase") != nil;
  if (!runningTests) {
    return UIApplicationMain(argc, argv, nil, NSStringFromClass([CVNAppDelegate class]));
  } else {
    return UIApplicationMain(argc, argv, nil, @"CVNTestAppDelegate");
  }
}

/*
Add your test app delegate to your test target looking like:

CVNTestAppDelegate.h

@interface CVNTestAppDelegate : NSObject<UIApplicationDelegate>

 
@end


CVNTestAppDelegate.m

#import "CVNTestAppDelegate.h"

@implementation CVNTestAppDelegate

 
@end
