Rasa 2.X Form Unit Tests

Rasa Open Source
2

@jslapp This is how I used to test forms in rasa 1.10 - for Rasa 2 you just need to slightly update this as I commented out in the code (it is not a complete code but I hope it gives you the idea).

@pytest.mark.parametrize(
    "slots,expected_events",
    [
        (
            {
                "slot1": True,
                "slot2": None,
            },
            [
                SlotSet("slot1", None),
            ],
        ),
    ],
)
    def test_my_form(
        default_dispatcher_collecting,
        default_domain_dict,
        default_sender_id,
        slots,
        expected_events,
    ):
        test_action = ActionMyForm() # ->  RASA2: change this to ActionMyFormSubmit()

        tracker = get_tracker(default_sender_id, slots_dict=slots)

        events = test_action.submit(
            default_dispatcher_collecting, tracker, default_domain_dict
        ) ## RASA2: change .submit to .run
        assert events == expected_events
