无法 运行 Robolectric 和带有 FragmentContainerView 的 Espresso
Unable to run Robolectric and Espresso with a FragmentContainerView
我一直在尝试 运行 Robolectric 和 Espresso，但我还没有成功。在试图找出导致此问题的原因之后，我意识到 activity 中的 FragmentContainerView 导致了此问题，我不确定如何解决它。
我决定创建一个空白项目，我认为可能是我项目中的某些东西导致了这个问题，我在空白项目上遇到了同样的问题。
这是我正在测试的当前设置。

MainActivityTest (androidTest)：此仪器测试 运行s 在 emulator/device 中没有预期的问题。

MainActivityTest（测试）：此测试无法 运行，它会抛出下面的异常，并且只有在我注释掉 activity_main.xml 布局中的 FragmentContainerView 时它才会起作用。
@RunWith(AndroidJUnit4.class)

@Test
public void testMainActivityIsVisible() {

}
}
尝试 运行 使用 robolectric 和浓缩咖啡进行测试后收到异常：
java.lang.Exception: Main looper has queued unexecuted runnables. This might be the cause of the test failure. You might need a shadowOf(getMainLooper()).idle() call.

非常感谢任何帮助！
我想通了这个问题。导致这无法正常工作的原因是导航组件的以下依赖性。
// Jetpack Compose Integration
implementation "androidx.navigation:navigation-compose:2.4.0-alpha01"
在我删除它之后，它不仅解决了我的 robolectric 和 espresso 问题，还解决了另一个导航测试问题。我不确定最新版本中发生了什么，但是，由于我更新了特定的依赖项，它似乎与 robolectric 和导航测试都不兼容。
我一直在尝试 运行 Robolectric 和 Espresso，但我还没有成功。在试图找出导致此问题的原因之后，我意识到 activity 中的 FragmentContainerView 导致了此问题，我不确定如何解决它。
我决定创建一个空白项目，我认为可能是我项目中的某些东西导致了这个问题，我在空白项目上遇到了同样的问题。
这是我正在测试的当前设置。

MainActivityTest (androidTest)：此仪器测试 运行s 在 emulator/device 中没有预期的问题。
@RunWith(AndroidJUnit4.class)
public class MainActivityTest {
@Rule
public ActivityScenarioRule<MainActivity> mainActivityRule =
new ActivityScenarioRule<MainActivity>(MainActivity.class);
@Test
public void testMainActivityIsVisible() {

MainActivityTest（测试）：此测试无法 运行，它会抛出下面的异常，并且只有在我注释掉 activity_main.xml 布局中的 FragmentContainerView 时它才会起作用。
@RunWith(AndroidJUnit4.class)
public class MainActivityTest {
@Rule
public ActivityScenarioRule<MainActivity> mainActivityRule =
new ActivityScenarioRule<MainActivity>(MainActivity.class);
@Test
public void testMainActivityIsVisible() {
onView(withId(R.id.mainActivityConstraintLayout)).check(matches(isDisplayed()));
}
}
尝试 运行 使用 robolectric 和浓缩咖啡进行测试后收到异常：
java.lang.Exception: Main looper has queued unexecuted runnables. This might be the cause of the test failure. You might need a shadowOf(getMainLooper()).idle() call.

所以，我尝试使用异常中的建议：
@RunWith(AndroidJUnit4.class)
@LooperMode(LooperMode.Mode.PAUSED)
public class MainActivityTest {
@Rule
public ActivityScenarioRule<MainActivity> mainActivityRule =

@Test
public void testMainActivityIsVisible() {
Shadows.shadowOf(Looper.getMainLooper()).idle();
onView(withId(R.id.mainActivityConstraintLayout)).check(matches(isDisplayed()));
}
}
但是我遇到了同样的异常：

非常感谢任何帮助！
我想通了这个问题。导致这无法正常工作的原因是导航组件的以下依赖性。
// Jetpack Compose Integration
implementation "androidx.navigation:navigation-compose:2.4.0-alpha01"
在我删除它之后，它不仅解决了我的 robolectric 和 espresso 问题，还解决了另一个导航测试问题。我不确定最新版本中发生了什么，但是，由于我更新了特定的依赖项，它似乎与 robolectric 和导航测试都不兼容。
