code: @Deprecated
    public static <T extends Fragment> FragmentController<T> buildFragment(Class<T> fragmentClass) {
      return FragmentController.of(ReflectionHelpers.callConstructor(fragmentClass));
    }
docs: Creates a FragmentController for the given fragment class.
  
  <p>FragmentController provides low-level APIs to control its lifecycle. Please consider using
  {@link androidx.fragment.app.testing.FragmentScenario} instead, which provides higher level
  APIs and works with instrumentation tests too.
  
  @deprecated Native Fragments have been deprecated in Android P. Android encourages developers
  to use androidx fragments, to test these use FragmentScenario.
