我正在尝试使用androidx测试库的新FragmentScenario API进行本地测试和仪器测试(androidTest)。该API在本地环境中运行良好，但在仪器测试中会出现错误：java.lang.AssertionError:Activity never becomes requested state "[RESUMED, DESTROYED]"(last lifecycle transition="PRE_ON_CREATE")"
请帮助我解决仪器测试(androidTest)中的问题。
请检查完整的错误详细信息：
java.lang.AssertionError: Activity never becomes requested state "[RESUMED, DESTROYED]" (last lifecycle transition = "PRE_ON_CREATE")

仪器测试（androidTest）代码如下：
@RunWith(AndroidJUnit4::class)
class LoginFragmentTest1 {
@Test
fun dummyTest() {
val scenario = launchFragmentInContainer<LoginFragment>()
onView(ViewMatchers.withId(R.id.user_name)).perform(ViewActions.typeText("Hello World!"))
onView(ViewMatchers.withId(R.id.user_name)).check(matches(withText("Hello World!")))
}
}
本地单元测试代码是：
@RunWith(AndroidJUnit4::class)
@Config(application = MyApplication::class, shadows = [ShadowAndroidXMultiDex::class])
class LoginFragmentTest2 {
@Test
fun dummyTest() {
val scenario = launchFragmentInContainer<LoginFragment>()
onView(ViewMatchers.withId(R.id.user_name)).perform(ViewActions.typeText("Hello World!"))
onView(ViewMatchers.withId(R.id.user_name)).check(matches(withText("Hello World!")))
}
}
