Sample with koin, fragment and viewModel

[ulx]

Hi, I try to create UI test with koin, fragment and viewModel (architecture component)

@RunWith(AndroidJUnit4::class)
class LoginFragmentTest{
@before
fun init() {
startKoin(hsApp + viewModel + api)
activityRule.activity.setFragment(testFragment)
EspressoTestUtil.disableProgressBarAnimations(activityRule)
}
@test
fun loading() {
testFragment.model.loginLoading.value = true
Espresso.onView(ViewMatchers.withId(R.id.login_button)).check(ViewAssertions.matches(ViewMatchers.isEnabled()))
}
}

@OpenForTesting
class LoginFragment : HSFragment() {
val TAG = javaClass.simpleName
val model: LoginViewModel by viewModel()
val modelConfig: ConfigViewModel by viewModel()
val router : Router by inject()
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
model.loginSuccess.observe(this, Observer { response ->
Log.d(TAG, response.toString())
context?.let {
router.homeActivity(it)
}
})
model.failure.nonNull().observe(this) { it?.let { showError(it) } }
model.loginLoading.nonNull().observe(this) { state -> loginButton.isEnabled = !state}
}
}

I recived this error

Maybe, Do you have any test with koin, fragment and viewModel
