Tests failing cus of error: type 'MockRtcEngine' is not a subtype of type 'RtcEngineImpl' in type cast

[lewooz]

Before v6.2.3 I could easily mock RtcEngine class and run tests but after updating to the most recent version my tests are no longer working. This is the error I am getting:

I am using mocktail package to mock RtcEngine and stub it's methods. When I downgrade to 6.2.2 everything works fine.

Any help would be greatly appreciated.

The createAgoraRtcEngine returns the RtcEngineImpl underlying

Agora-Flutter-SDK/lib/src/agora_rtc_engine_ext.dart

Line 44 in 64dbdad

return impl.RtcEngineImpl.create();

How does your test case look like, maybe it's not a good way to mock the RtcEngine interface if your test case is combined with the AgoraVideoView.

I am getting the error when each widget test is finished which means I am getting the error only when the AgoraVideoView is getting disposed. This is how I am mocking the RtcEngine:

As I said I am not having issues with 6.2.2. A change made in 6.2.3 is the cause of the issue. My hunch is that the problem might be happening because extension methods can not be stubbed.

If the rendering is not a matter of your test, I think you'd better mock VideoViewController and pass it to your AgoraVideoView implementation.
