    UIApplication.sharedApplication.delegate.window.rootViewController = viewController;
    
    // assert no modal view is presented
    XCTAssertNil(viewController.presentedViewController);
    
    // simulate button tap which shows modal view controller
    [viewController.deleteButton sendActionsForControlEvents:UIControlEventTouchUpInside];
    
    // assert that modal view controller is presented
    XCTAssertEqualObjects(viewController.presentedViewController.class, MyModalViewController.class);
    

    As far as I tested it, this works for iOS7 and iOS8. Didn't try on iOS6 however.
