[alexbadia1]

You will need to change the pubspec.yaml to add bloc_test functionality Some general things to test:

• Verify the initial state of the bloc/cubit is correct.
• Test each function of the bloc or cubit
  • Be sure to thoroughly cover all (if not most) possible output values

Some tips:

• Use Equatable to compare states

Testing specifically for blocs and their events

• Add bloc_test dependency
• Inject repositories by creating mock instances of repositories
• Add the event to the bloc
• Check for expected states (not this could be a stream which needs emitsInOrder)

Test for Network Errors!

• You will need .thenThrow(Object())

Blocs that depend on each other:

• bloc_test package allows mocking other blocs with MockBloc
