Robolectric.setupActivity() is deprecated in Android unit test

Question

I'm trying to use Robolectric framework to run a simple Unit test, although I got that Robolectric.setupActivity() is deprecated.

@RunWith(RobolectricTestRunner.class)
public class MainActivityFragmentTest {

    MainActivity mainActivity;

    @Before
    public void setUp() {
        mainActivity = Robolectric.setupActivity(MainActivity.class);
    }

    // Rest of Test

How can I solve that? Thanks for help in advance..

Use ActivityScenario, documetation is here: ActivityScenario

try(ActivityScenario<MyActivity> scenario = ActivityScenario.launch(MyActivity.class)) {
 scenario.onActivity(activity -> {
   assertThat(activity.getSomething()).isEqualTo("something");
 });
}
