Aren't these last two tests kind of the same thing? Seems like we can just keep the second one and rename to <code> canOpenAndCloseDrawer()</code>.

Also, this is purely stylistic, but if you want to keep the same FEST style of assertions throughout all the tests you can use

    assertThat(drawerLayout.isDrawerOpen).isTrue();

and

    assertThat(drawerLayout.isDrawerOpen).isFalse();
