使用 espresso 的 testUI (Jenkins)

该应用程序正在本地通过 espresso 测试，我的意思是直接到设备和 genymotion 模拟器。当我使用 Jenkins 构建应用程序的映像时。浓缩咖啡测试未成功，我收到此错误。

JENKINS:

 java.lang.RuntimeException: Waited for the root of the view hierarchy to have window focus and not be requesting layout for over 10 seconds. If you specified a non default root matcher, it may be picking a root that never takes focus. Otherwise, something is seriously wrong. Selected Root:

Stacktrace 意味着 Espresso 找不到应用程序窗口。在模拟器屏幕上进行测试时，屏幕通常隐藏在屏幕锁定后面。您需要使用一些代码以编程方式禁用屏幕锁定。 对我来说解锁屏幕最方便的方法是使用 Robotium。它有solo.unlockScreen()方法。我已将其放入测试生命周期的 setUp() 方法中。
