Enzyme's mount() fails to render the whole tree

[manuelmorales]

As you can read here enzymejs/enzyme#470, it won't work. And by the looks of https://github.com/lelandrichardson/react-native-mock/blob/master/src/components/View.js#L284 it is expected.

My question is: Is it part of your ideal for this library to keep extending it so that eventually, things like these work? Or would that be totally off scope for this library?

I'd vote for allowing children, but then we'll have to mock all this native-connecting Apis. At some point you have to make the cut

The idea of this library is to use the 'Shallow' render feature of enzyme. In an ideal world, everything would render accurate children, and we wouldnt have any issue like this. This kind of a change would be rather monumental, and complicated to implement, but i'm open to the change!

Any help with this would be greatly appreciated

[manuelmorales]

Understood guys. Thanks for the clarification. I don't feel capacitated to take over this myself as I'm quite new to react and react native yet. You can close this issue if you like.

Thank you!

@manuelmorales any workaround for this, or any tips on getting things to work?

We made a fork at https://github.com/Root-App/react-native-mock-render that will allow fully rendering native components with enzyme's mount(). We wrote about it at https://blog.joinroot.com/mounting-react-native-components-with-enzyme-and-jsdom/

We'd be happy to contribute a PR back into react-native-mock, but it'd be a breaking API change.

[RealOrangeOne]

@dan-manges that looks like great work. Looking through your code i'm not seeing any massively breaking changes, but I may be wrong.

I'm currently in the process of doing a major rewrite that'll fix this issue once and for all in a much more reliable way. Whilst it's not finished yet, i'd love some feedback on it! There's an open PR to track this #120

[talarari]

@RealOrangeOne could you explain your approach to supporting mount in this PR? Is it similar to what's been done​ in react-native-mock-render?

[RealOrangeOne]

@talarari no, #120 is a complete rewrite. Rather than using complete mocks as the current version of react-native-mock and react-native-mock-renderer do. #120 uses the direct react-native code when rendering, in mostly the same way jest does.
