Hello everyone!! I’m testing a fragment and I have a problem. I initialize it doing this:

@Test
fun testFragment() {
    launchFragmentInContainer<CountryFragment>(themeResId = R.style.AppTheme)
    ...
}

My style is:

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
...
</style>

onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) in the fragment is not called and the actionbar is hide. If I use R.style.ThemeOverlay_MaterialComponents_Dark_ActionBar for instance , onCreateOptionsMenu is called and the actionbar is shown but I get this error:

android.view.InflateException: Binary XML file line #12 in com.jaimegc.covid19tracker:layout/item_total: Binary XML file line #12 in com.jaimegc.covid19tracker:layout/item_total: Error inflating class com.google.android.material.card.MaterialCardView
Caused by: android.view.InflateException: Binary XML file line #12 in com.jaimegc.covid19tracker:layout/item_total: Error inflating class com.google.android.material.card.MaterialCardView
Caused by: java.lang.reflect.InvocationTargetException
...
Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.MaterialComponents (or a descendant).

And using R.style.Theme_MaterialComponents I have the same problem as in the first case. What would be the way to initialize the fragment with its actionbar? I could create a toolbar but I would like to avoid it if there are alternatives. Thanks!
