我正在使用 Android Studio 2.2 并尝试录制 Espresso 测试。我无法向 Toast 消息、EditText 错误消息或 Snackbar 消息添加断言。我的 Snackbar 文本低于异常
android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: (with id: com.example.root.myapplication:id/snackbar_text and with text: is "enter email" and Child at position 0 in parent Child at position 2 in parent an instance of android.view.ViewGroup and is displayed on the screen to the user)
任何帮助表示赞赏。
谢谢
