Question

在Android Ui测试中，我想点击对话框中的微调项目，但会弹出这个错误：

va.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:

我试过了

onData(allOf(is(instanceOf(String.class)),containsString("A4"))).inRoot(isPlatformPopup()).perform(click());

和

onView(withText(containsString("A4"))).inRoot(isFocusable()).check(matches(isDisplayed()));

和

onView(withText(containsString("A4"))).inRoot(withDecorView(not(getActivity().getWindow().getDecorView()))).check(matches(isDisplayed()));

但它们都不起作用...... 谁能告诉我如何获得ralavant root？

Answer 1

当我在DialogFragment中使用Spinner时，我遇到了同样的错误。这是唯一适用于我的代码：

onView(withText(containsString("A4"))).inRoot(isPlatformPopup()).check(matches(isDisplayed()));

Answer 2

万一发生在任何人的Travis构建中（具有完全相同的日志）。请检查this。

有完全相同的问题，并通过创建具有较低目标版本的avd（19）来解决。

我尝试过但没有工作的事情：

在UI测试中添加unlockScreen() @Before方法。
添加/删除adb shell input keyevent 82 &。
删除不同的emulator命令选项-no-skin或-no-audio或-no-window。现在我-no-window就可以了。

最后，改变从

echo no | android create avd --force -n test -t android-24 --abi armeabi-v7a

到

echo no | android create avd --force -n test -t android-19 --abi armeabi-v7a

完美地解决了这个问题。

Answer 3

只需更新travis.yml中的构建工具：

在此文件.travis.yml中：您应该拥有此before_install: - echo yes | android update sdk --all --filter build-tools-26.0.1 --no-ui --force
同样在.travis.yml：

script: echo no | android create avd --force -n test -t android-22
--abi armeabi-v7a emulator -avd test -no-audio -no-window & 
android-wait-for-emulator 
adb shell settings put global window_animation_scale 0 &
adb shell settings put global transition_animation_scale 0 &
adb shell settings put global animator_duration_scale 0 &
adb shell input keyevent 82 &

Answer 4

当对话框弹出窗口包含微调器项目（下拉列表）时，我也遇到类似的问题，我的单击无法在任何微调器项目上执行，并且得到相同的错误。我通过在RootMatchers中使用onData（）方法找到了解决方案：

onData(anything()).inRoot(RootMatchers.isPlatformPopup()).atPosition(1).perform(click());

请注意， atPosition（） 中的索引值是微调器列表中项目的索引值。

Answer 5

显示系统对话框时（例如“关闭电源”或“不幸的是，启动器已停止”（后台应用程序崩溃），并且您尝试在该对话框可见的情况下运行Espresso单元测试，就会发生此错误。 / p>

您可以通过在运行测试之前关闭系统对话框来解决此问题：

MyActivity activityUnderTest = activityTestRule.getActivity();
activityUnderTest.sendBroadcast(new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));

或使用adb在命令行上发送广播：

adb shell am broadcast -a android.intent.action.CLOSE_SYSTEM_DIALOGS

另一个原因是当后台应用程序冻结（ANR）或运行缓慢时，系统对话框显示“应用程序无响应。您要关闭它吗？[等待] [确定]” ：

如果您在此对话框可见的情况下尝试运行Espresso测试，它们将全部失败并显示错误。

无法以编程方式关闭此对话框。但是您可以在命令行上使用adb发送screen taps或key strokes来关闭它。例如：

# On a 320x480 screen, click at screen location [x=233,y=293] to tap an "OK" dialog button.
# Just in case there is a "Launcher isn't responding" system dialog.
adb shell input tap 233 293

或

# Send keystroke Arrow Right
sleep 3; adb shell input keyevent 22
# Send keystroke Arrow Right again
sleep 3; adb shell input keyevent 22
# Send keystroke Enter to press a button on the dialog
sleep 3; adb shell input keyevent 66
