浓咖啡-全屏活动执行操作失败-InjectEventSecurityException [英] Espresso - Perform action fails on fullscreen activity - InjectEventSecurityException

问题描述

我浪费了两天时间试图对全屏活动执行点击操作.

I wasted two days trying to perform click action on a fullscreen activity.

1. 使用全屏活动代码模板在android studio中创建新项目

2. 为该活动编写浓咖啡测试以执行点击

1. Create a new project in android studio using fullscreen activity code template

2. Write an espresso test for the activity to perform click

public class FullscreenActivityTest 
              extends ActivityInstrumentationTestCase2<FullscreenActivity> {
public FullscreenActivityTest() {
    super(FullscreenActivity.class);
}

@Override
protected void setUp() throws Exception {
    super.setUp();
    getActivity();
}

public void testClickingOnLayout() {
    onView(withId(R.id.fullscreen_content)).perform(click());
}

}

失败

android.support.test.espresso.PerformException: 
Error performing 'click' on view 'with id: com.example.espressodefect:id/fullscreen_content'
...
Caused by: android.support.test.espresso.PerformException: 
Error performing 'Send down montion event' on view 'unknown'.
...
Caused by: android.support.test.espresso.InjectEventSecurityException: java.lang.SecurityException: 
Injecting to another application requires INJECT_EVENTS permission

完整堆栈位于此处.

我没有运气尝试过以下方法:

I have tried the following with no luck:

• 模拟器上没有锁定屏幕. (还使用WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD)
更新了活动
• 所有动画均已关闭
• 没有屏幕键盘，或应用程序顶部没有覆盖的任何东西.
• 还遵循了此处上的说明.
• JUnit3和JUnit4样式(AndroidJUnitRunner)
• <uses-permission>代表INJECT_EVENTS

• No lock screen on the emulator. (also updated activity using WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD)
• All animations turned off
• No on-screen keyboard, or anything overlayed on top of the app.
• Also followed instructions here at developer.android.com
• JUnit3 and JUnit4 styles (AndroidJUnitRunner)
• <uses-permission> for INJECT_EVENTS

在浓缩咖啡测试中，如果我使用非全屏活动(如使用空白活动创建的活动)，则执行操作的效果会很好.全屏上的相同操作失败.

In espresso test, performing actions work fine if I use non-fullscreen activity like the one created with blank activity. Same action on full screen fails.

我正在使用Espresso 2.0和支持库.

I am using Espresso 2.0 and support libraries.

我在做什么错了?

Espresso开发人员确认这是缺陷.请参阅问题140 .

Espresso dev confirmed this as defect. Please see issue 140.

推荐答案

此错误已在Espresso的最新版本中解决:

This bug was solved in the last release of Espresso:

Espresso 2.2.2，Runner/Rules 0.5(2016年2月22日，静默发布)-

Espresso 2.2.2, Runner/Rules 0.5 (2016-02-22, silent release) - https://google.github.io/android-testing-support-library/downloads/release-notes/index.html

在我的项目中，我已将/app/build.grandle中的依赖项从以下位置更改:

In my project, i've changed the dependency in the /app/build.grandle from:

androidTestCompile'c​​om.android.support.test.espresso:espresso-core:2.1'

到

androidTestCompile'c​​om.android.support.test.espresso:espresso-core:2.2.2'

在AndroidStudio中:Grandle Scripts => build.gradle文件
