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

In Swift, I prefere to bypass a normal execution path inside application: didFinishLaunchingWithOptions:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    guard normalExecutionPath() else {
        window = nil
        return false
    }

    // regular setup

    return true
}

private func normalExecutionPath() -> Bool {
    return NSClassFromString("XCTestCase") == nil
}

Code inside guard will remove any views created from storyboard.
