Problems testing custom activities or fragments that not inherit directly from Activity or Fragment about android-test HOT 5 CLOSED

Without a complete sample it will be difficult to provide guidance here. Is it possible to build a repro case using https://github.com/android/testing-samples/tree/main/ui/espresso/BasicSample as a baseline?

from android-test.

What more do you need? You have the code for the test class. when y click to launch the test file it shows the other errors. I cannot build a repro case because i'm in a professional complex project. But HomeActivity inherits from

class HomeActivity : BasePresenterActivity<HomeActivityPresenter>(), BottomNavigator, NotificationManager.InAppNotificationInterface, INotificationView, HomeActivityPresenter.Contract, CustomInAppMessaging.InAppNotificationInterface, ChannelSelectorFragment.ChannelSelectorFragmentInteractionListener

abstract class BasePresenterActivity<P : RPresenter<*, *>> : BaseActivity() {

abstract class BaseActivity : AppCompatActivity()

The test class:

@RunWith(AndroidJUnit4::class)
class FiltersFragmentTest {

    @get:Rule
    val sc: ActivityScenario<HomeActivity> = ActivityScenario.launch(HomeActivity::class.java)

    @Before
    fun enterToFilterScreenFromFeed() {
        onView(withId(R.id.iv_filter)).perform(click())
        EspressoIdle.increment()
    }


    @Test
    fun ifSearchTextPresentAppbarRestoreTextShown() {
        onView(withId(R.id.etSearch))
            .check(matches(withParent(withId(R.id.searchInput))))
            .perform(replaceText("A")).perform(closeSoftKeyboard())
        onView(withId(R.id.tv_rightText))
            .check(matches(isDisplayed()))
    }
}

from android-test.

If y want to execute a test class with launchFragmentContainer from fragment scenario also complains that the generic class passed is not an instance of Fragment, and it is

from android-test.

I also tried to inherit directly from Fragment() and the import is correct androidx.fragment.app.Fragment

Same errors:
> Task :app:compileDebugAndroidTestKotlin FAILED e: file:///C:/Users/Usuario/Projectes/b4work-android/app/src/androidTest/kotlin/com/innopro/b4work/FiltersFragmentTest.kt:12:47 Type argument is not within its bounds: should be subtype of 'Fragment' e: file:///C:/Users/Usuario/Projectes/b4work-android/app/src/androidTest/kotlin/com/innopro/b4work/FiltersFragmentTest.kt:16:31 Cannot access class 'androidx.fragment.app.FragmentFactory'.

from android-test.

The new code for the test class

package com.my.package

import androidx.fragment.app.testing.FragmentScenario
import androidx.test.ext.junit.runners.AndroidJUnit4
import com.innopro.b4work.newcode.presentation.filterview.FiltersFragment
import org.junit.Before
import org.junit.runner.RunWith

@RunWith(AndroidJUnit4::class)
class FiltersFragmentTest {

    private lateinit var sc: FragmentScenario<FiltersFragment>

    @Before
    fun setup() {
        sc = FragmentScenario.launchInContainer(FiltersFragment::class.java)
    }
}

from android-test.
