how to check a toast shown in fragment(a dialog fragment, not full screen)? #179

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.MainActivity is FragmentActivity and shows a dialogFragment which is not full 
screen.
2.there is a button in DialogFragment. if press the button, a toast will show.
3.i want to test whether the toast is shown.

the code in test:
onView(withText("test")).inRoot(withDecorView(not(is(getActivity().getWindow().g
etDecorView())))).check(matches(isDisplayed()));

What is the expected output? What do you see instead?
i know this code works in activity, but fails in fragment.
the exception:
android.support.test.espresso.NoMatchingViewException: No views in hierarchy 
found matching: with text: is "test"

This WAI. The question was asked many times before, please follow this thread 
on our forum: 
https://groups.google.com/forum/#!msg/android-test-kit-discuss/uaHdXuVm-Bw/YUphd
IMW9GUJ

The gist is, that this is not supported and hard to get right in a thread safe 
way. The proper solution to verify this behaviour in a reliable way is to use 
an Interface + Mockito. Since testing a Android Framework API does not really 
make sense verification that the call actually happened is a sufficient test.
