How to test for the appearance of a Toast message

Question

Would anyone know how to test for the appearance of a Toast message on an Activity?

I\'m using code similar to what the OP posted on this question for testing my pro

Answer 1

We actually can now test for toast messages using robolectric. The example below is how our team is doing this for now:

    @Test
    public void ccButtonDisplaysToast() throws NullPointerException {
        Button ccRedButton = (Button) findViewById(R.id.cc_red);
        cc_red.performClick(); --> this calls the actual onClickListener implementation which has the toast.
        ShadowLooper.idleMainLooper(YOUR_TIME_HERE); --> This may help you.
        assertThat(ShadowToast.getTextOfLatestToast().toString(), equalTo("TEST_YOUR_TEXT_HERE"));
    }

Hope this helps
