The debugger has the model, msg and the new model. So if you tell it that the new model is indeed the expected return value from update msg model, it can write that test for you. To use Counter as an example:
model = 0 update msg model = case msg of Up -> model + 1 Down -> model - 1 My model starts as 0. I send Up, I get 1. This is as expected so I accept. update Up 0 == 1 is now a test that the code has to pass. I have raised this here as a feature request: https://github.com/elm-lang/virtual-dom/issues/75 (see also Peter Gao's comment). Can you foresee any problems with this feature? Would it in fact be useless? I don't have a lot of testing experience. -- You received this message because you are subscribed to the Google Groups "Elm Discuss" group.
