android - 即使添加 InstantTaskExecutorRule 后，android.os.Looper 中的方法 getMainLooper 未被模拟仍然发生

Question

我收到 getMainLooper in android.os.Looper not mocked 异常。我已经添加了 InstantTaskExecutorRule 规则，但它仍然不适合我。

添加此类并在测试类顶部添加注释后即可正常工作。

@ExtendWith(InstantExecutorExtension::class)

class InstantExecutorExtension : BeforeEachCallback, AfterEachCallback {

    override fun beforeEach(context: ExtensionContext?) {
        ArchTaskExecutor.getInstance()
            .setDelegate(object : TaskExecutor() {
                override fun executeOnDiskIO(runnable: Runnable) = runnable.run()

                override fun postToMainThread(runnable: Runnable) = runnable.run()

                override fun isMainThread(): Boolean = true
            })
    }

    override fun afterEach(context: ExtensionContext?) {
        ArchTaskExecutor.getInstance().setDelegate(null)
    }
}
