Unit Testing in Xcode, does it run the app?

Question

I\'m running into a strange problem that I haven\'t run into before.

When you do cmd+U to run your Unit Tests (OCUnit for example) does it actually call the main.m,

Answer 1

I found another solution to the problem:

int main(int argc, char * argv[])
{
    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, ({
            ![NSProcessInfo processInfo].environment[@"XCTestConfigurationFilePath"] ?
            @"AppDelegate" :
            nil;                
        }));
    }
}

Answer 2

Using xCode 7 and xCtool

xctool is capable of executing unit tests without running the app.

To get this working,

1 . Update target settings to run without a host app.

Select your project --> then test target --> Set the host application to none.

2. Install xctool , if you don't have it.

brew install xctool

3. Run the tests using terminal with xctool.

xctool -workspace yourWorkspace.xcworkspace -scheme yourScheme run-tests -sdk iphonesimulator

Answer 3

You can do that by setting the Host Application to None in your Tests Target.

Answer 4

I use the approach of Tomasz Bak plus some code of dwb answer and come up with the following:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

    BOOL runningTests = NSClassFromString(@"XCTestCase") != nil;
    if (runningTests) {
        self.window.rootViewController = [UIViewController new];
        return true;
    }

    // Your normal code below this
    ....
}
