Bloc: Mock a bloc for unit tests

[jkyon]

Hi

It is there a way to create a mock of a bloc for unit tests? I tried to create a mock but its current state is null.

Thank you in advance

Hi @jkyon 👋
Thanks for opening an issue!

Regarding your question you can create a mock bloc using mockito like so:

class MockBlocA extends Mock implements BlocA {}

you can then create an instance like so

void main() {
  group('Tests', () {
    BlocA blocA;

    setUp(() {
        blocA = MockBlocA();
    });
  });
}

Then you can mock the currentState in your tests like so:

when(blocA.currentState).thenAnswer((_) => BlocAState());

Hope that helps and great question! 👍
