Question

我的应用程序显示一个启动画面。如何让我的测试等待主屏幕出现？无需等待我的测试在应用程序启动后立即失败。

// in application:didFinishLaunchingWithOptions: of my AppDelegate... 
SplashViewController *splashVC = [[SplashViewController alloc] init]; 
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 
self.window.rootViewController = splashVC; 
[self.window makeKeyAndVisible]; 

NSTimeInterval splashScreenDuration = 0.5; 
[NSTimer scheduledTimerWithTimeInterval:splashScreenDuration 
           target:self 
          selector:@selector(hideSpashScreenAndDisplayMainViewController) 
          userInfo:nil 
           repeats:NO]; 

// hideSpashScreenAndDisplayMainViewController method simply sets self.window.rootViewController to the main view controller.

EarlGrey提供GREYCondition API，你可以在你的安装方法或特定测试，以EarlGrey等你等待启动画面消失的开始使用。你可以使用类似于他们在faq page中的代码来做到这一点。

// Wait for the main view controller to become the root view controller. 
    BOOL success = [[GREYCondition conditionWithName:@"Wait for main root view controller" 
              block:^{ 
    id<UIApplicationDelegate> appDelegate = [UIApplication sharedApplication].delegate; 
    UIViewController *rootViewController = appDelegate.window.rootViewController; 
    return [rootViewController isKindOfClass:[MainViewController class]]; 
    }] waitWithTimeout:5]; 

    GREYAssertTrue(success, @"Main view controller should appear within 5 seconds.");
