Jest tests about mobx-react HOT 10 CLOSED

Personally didn't do anything significantly with tape yet, but I think you would at least need to avoid stubbing of the mobservable and mobservable-react packages to test anything useful?

I don't use Tape, but rather Jest, and I do have those packages called out not to not mock them automatically but I can't get a single test to run. Not sure what the problem is at this time.

Do you have a shareable branch somewhere? I can take a look

Just updated

• npm install
• npm test

I saw that some other teams in our company have Jest / React / Mobservable tests, so it is possible at least :)

I've had nothing but trouble keeping my Jest tests working in my other
project - seems every release of RN breaks something.

Hopefully you find a team that can provide some insight

Thanks for looking at it.

Wow, Jest is a real horror to setup, I changed the setup a bit that got me at least beyond the initial "FAIL" I got without any further error when including components.

See: mweststrate/mobservable-react-native-counter@76dba47

The script preprocesser seems to fix it that at least the tests start when referring to a component. But after that it throws compile errors. Note sure how to setup multiple preprocessors. It seemed that the require('react-native') import in the mobservable-react module broke without the preprocess. But so far Jest is one big mistery for me. I happily continue not using it 😉

Rats! Sorry to hear you didn't make any headway! I had all my fingers and toes crossed.

The ReactJS Conf is going on now - I've been watching it. They haven't mentioned Jest. No surprise -it's the read headed step child.

Once I get my server stuff settled down I want to pick up the mobservable rewrite w/ my Snowflake/Redux app. It would be nice to run tests. Maybe by then I'll have some insights.

@mweststrate is there any chance that compatibility with Jest will be fixed soon?

@kitze From your tweets it seems the question has been answered, but for future reference

jest.mock('react-dom'); seems to be needed (facebook/react#7386). See also https://semaphoreci.com/community/tutorials/how-to-test-react-and-mobx-with-jest
