java.lang.IllegalStateException: Cannot move to state "RESUMED" since the Activity has been destroyed already

Question

I have updated my test cases dependencies from this to this(as given below in code snippet ), since then I am facing this error of java.lang.NullPointerException: Cannot run onActivity since Activity has been destroyed already . while earlier this test case was working fine.

But Now its not wokring, giving error at line scenarioRule.getScenario().onActivity(activity -> {

// this
testImplementation 'org.robolectric:robolectric:4.5-beta-1'
    testImplementation 'androidx.test.espresso:espresso-core:3.4.0'
    testImplementation 'androidx.test.espresso:espresso-contrib:3.4.0'
    androidTestImplementation 'androidx.test:rules:1.4.0'

// to this
testImplementation 'org.robolectric:robolectric:4.14.1'
    testImplementation 'androidx.test.espresso:espresso-core:3.6.1'
    testImplementation 'androidx.test.espresso:espresso-contrib:3.6.1'
    androidTestImplementation 'androidx.test:rules:1.6.1'



@RunWith(AndroidJUnit4.class)
public class NfcCardReaderActivityTest {

    @Rule
    public ActivityScenarioRule<NfcCardReaderActivity> scenarioRule
            = new ActivityScenarioRule<>(NfcCardReaderActivity.class);

    @Test
    public void testHelperIsShown() {

            scenarioRule.getScenario().onActivity(activity -> {
                activity.onResume();

                checkHasText(
                        activity,
                        R.id.info_text,
                        R.string.helper_description
                );
            });
    }

So I got the solution

Basically the solution I found belongs to this link https://github.com/robolectric/robolectric/issues/8661

There was a problem with sdk 33 with respective to roboelectric. And I was testing on sdk 33

So Nfcadapter.getdefaultAdapter() was coming null

So I have to use MockStatic for NfcAdapter

try(MockedStatic<NfcAdapter> nfcMockAdapter = mockStatic(NfcAdapter.class)) {
        nfcMockAdapter.when(() -> NfcAdapter.getDefaultAdapter(any()))
                .thenReturn(mock(NfcAdapter.class));
        // Your code here
    }
