Фрагмент, не связанный с менеджером фрагментов ⇐ Android

[Anonymous]

Я пишу несколько инструментальных тестов для приложения с одним действием и несколькими фрагментами, используя компонент навигации.

Код для моего экрана-заставки следующий: ниже:

class SplashFragment : Fragment(), KodeinAware {

override val kodein by Admin.instance.kodein

private var realm: Realm? = null

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
return inflater.inflate(R.layout.splash, container, false)
}

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)

(activity as? AppCompatActivity)?.supportActionBar?.hide()

realm = Realm.getInstance(RealmUtil.realmConfig)

val result = realm!!.where().findFirst()
val user = if (result != null) realm!!.copyFromRealm(result) else null

Handler().postDelayed({
if (user == null)
findNavController().navigate(R.id.action_splashFragment_to_loginFragment) //navigate to login screen if no user exists
else
findNavController().navigate(R.id.action_splashFragment_to_businessListFragment) //navigate to business list if user already logged in
}, 2000)
}

override fun onDestroy() {
super.onDestroy()

realm?.close()
}
}


Я пытаюсь протестировать фрагмент, который идет после заставки, но постоянно получаю следующую ошибку:

Мой тестовый класс выглядит следующим образом:

@RunWith(AndroidJUnit4::class)
@MediumTest
class SignInTest {

@get: Rule
val login = ActivityScenarioRule(Home::class.java)

@Test
fun loginWithoutEmail_ShouldDisplayError() {
val scenario = launchFragmentInContainer()

onView(withId(R.id.password)).perform(typeText("samplePassword"), closeSoftKeyboard())
onView(withId(R.id.login)).perform(click())

onView(withId(com.google.android.material.R.id.snackbar_text)).check(matches(withText(R.string.enter_email)))
}

@Test
fun loginWithoutPassword_ShouldDisplayError() {
val scenario = launchFragmentInContainer()

onView(withId(R.id.email)).perform(typeText("sample@password.com"), closeSoftKeyboard())
onView(withId(R.id.login)).perform(click())

onView(withId(com.google.android.material.R.id.snackbar_text)).check(matches(withText(R.string.enter_password)))
}
}


Ни одна из моих тестовых функций не будет выполнена из-за вышеупомянутой ошибки.
