I also not found any equals method which compare two int parameters. But I think there aren't designed Fest API to compare primitives. So, you can use simple JUnit API for compare primitives. Meanwhile I found this example:
FEST Android:
assertThat(view).isGone();
Regular JUnit:
assertEquals(View.GONE, view.getVisibility());
Please check this documentation. The ANDROID class containt many asserThan methods to compare android objects.
