simple JUnit test on Recyclerview in Kotlin

Question

I'm trying to implement a simple test but my test getting failed. I couldn't see why it's failing

My test case is: Trying to click 5th position in the RecyclerView list. My test code as below.

@RunWith(AndroidJUnit4::class)
class RecyclerListActivityTest{

    @Rule @JvmField
    var activityRule = ActivityTestRule<RecyclerListActivity>(
        RecyclerListActivity::class.java
    )

    @Test
    fun recyclerTest(){
               onView(withId(R.id.post_list)).perform(RecyclerViewActions.actionOnItemAtPosition<RecyclerView.ViewHolder>(5,ViewActions.click()))
    }

}

Error:

E/TestRunner: androidx.test.espresso.PerformException: Error performing 'androidx.test.espresso.contrib.RecyclerViewActions$ActionOnItemAtPositionViewAction@81f0980' on view 'with id: com.kabelash.gitrepos:id/post_list'.

        at androidx.test.espresso.ViewInteraction.desugaredPerform(ViewInteraction.java:178)
        at androidx.test.espresso.ViewInteraction.perform(ViewInteraction.java:119)

Note: When I run the app it's works fine without any errors.

Does this answer your question? [Android Espresso: PerformException](https://stackoverflow.com/questions/44005338/android-espresso-performexception) — MichaelStoddart, Dec 06 '19 at 15:57
I tried this before posting my question. Anything else I have to check? — GK007, Dec 06 '19 at 16:14
