                                    @NonNull final CharSequence text,
                                    @BaseTransientBottomBar.Duration final int duration,

@Test public void testSetActionTextSize() { final MeliSnackbar snackbar = MeliSnackbar.make(view, TEST_STRING, Snackbar.LENGTH_INDEFINITE); final float newSize = 18; Assert.assertNotSame(newSize, getActionButton(snackbar).getTextSize()); snackbar.setActionTextSize(newSize); Assert.assertEquals(newSize, getActionButton(snackbar).getTextSize(), 0); }
