Android 单元测试套件在单个测试通过时挂起

如何解决Android 单元测试套件在单个测试通过时挂起

测试类 DummyTest 已经在代码库中存在很长时间了，但是这个测试冻结问题只发生在我添加 Firebase Crashlytics 日志记录之前的几次

enter image description here

class DummyTest {
    @Test
    fun test() {
        val fakeDataSource = Mockito.mock(DummyDataSource::class.java)
        Mockito.`when`(fakeDataSource.invoke()).thenReturn(Single.error(UnkNownError("shit happened")))
        Dummy(fakeDataSource)
    }
}


class Dummy(dataSource: DummyDataSource) {
    init {
        dataSource()
                .subscribe({
                    println("success")
                },{
                    if (true) throw RuntimeException(it.message)
                })
    }
}

class DummyDataSource {
    operator fun invoke(): Single<String> {
        return Single.just("some data")
    }
}

DummyTest 在 Android Studio 中运行时通过，尽管控制台中存在 CompositeException：

当然，冻结不会发生

  • DummyTest 被忽略 (@Ignore)
  • AND 当 throw new RuntimeException() 从 RxJava 的 onError 处理程序中删除时

./gradlew tests --debug 表明在同一测试之后似乎有无休止的等待“守护进程地址注册”

2021 年 3 月 15 日更新 看起来可能是 Firebase Crashlytics 导致了这种情况 当测试套件挂起时

   Locked ownable synchronizers:
    - <0x00000007a0026f20> (a java.util.concurrent.ThreadPoolExecutor$Worker)

Crashlytics 源代码 CrashlyticsController：

synchronized void handleUncaughtException(@NonNull final SettingsDataProvider settingsDataProvider,@NonNull final Thread thread,@NonNull final Throwable ex) {
        // ....

        try {
            Utils.awaitEvenIfOnMainThread(handleUncaughtExceptionTask);
        } catch (Exception var7) {
        }

    }

看起来 Crashlytics 没有在 catch {} 块中做任何事情，让测试运行器永远等待？

或者，latch.await() 中的 Utils.awaitEvenIfOnMainThread 只是永远阻塞线程？
