Wrapping of complex types seem to be broken

[AshesOfOwls]

I cannot seem to get any oneOfType, oneOf, etc complex propTypes to be correctly wrapped. The wrapped function always seems to be returning undefined for its type, and therefore never gets a generated value.

Currently using prop-types ^15.5.8.

@mcpants I just ran into this yesterday... Are you require-ing or import-ing your component before requiring this lib?

Try switching the import order, or just calling require('react-generate-props') one time at the very start of your test suite, and let me know if that fixes it.

If that works, great, but it's totally undocumented and I'd like to either document this gotcha or come up with a better solution. Sorry for the hassle!

@markalfred Worked great when importing as one of the first packages. Thanks!

👍 Good to hear @mcpants — I'm going to keep this open in case others run into it, and to ensure I come up with a better solution 😂

Doesn't work for me :/

component.js:
Component.propTypes = {
groups: PropTypes.arrayOf(PropTypes.shape({
    id: PropTypes.number.isRequired,
  })),
}

test.js:
import React from 'react';
import { shallow } from 'enzyme';
import Enzyme from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

import Component from './component';
import generateProps from 'react-generate-props'

Enzyme.configure({ adapter: new Adapter() });

let foo =  generateProps(Component)

the type in line: var generate = options.generators[propType.type]; is undefined

I have also tried with require and changing the order, but nothing worked for me.

prop-types version: 15.6.0

This is broken for me as well. I tried the suggestion of changing the order of import to no avail.

Its failing on any shape() PropType.

[markalfred]

@Duskfall since the groups prop isn't required, it won't be generated by default. As of the current version, optional props aren't generated by default. Could you try passing the { optional: true } opt to generateProps?

let foo =  generateProps(Component, { optional: true })

@markalfred updated my comment.

[AshCoolman]

the type in line: var generate = options.generators[propType.type]; is undefined

@Duskfall Ah yes, the latest commit seems to grief me in the same way

$ node --version
v9.2.0
$ yarn --version
1.3.2
$ rm -r node_modules/; yarn; yarn react:16; yarn build; yarn link;

Gives me this error

index.js:16 TypeError: Cannot read property 'bind' of undefined

Note: 0.3.0 works fine for me

Just to give an update: I've been thinking about and experimenting with solutions for this, but the only viable option I can come up with is: throw an error if a PropTypes.(anything) has been called before this library had a chance to wrap PropTypes correctly. This feels like a bit of a cop-out, but it will at least make it clear that this was the problem. I haven't been able to come up with any way to backfill previously-defined propTypes, and I haven't been able to reproduce this issue in any other ways, so this might be what we're stuck with. But I'll keep thinking about this and update if I have anything else. Sorry for the delay in getting this completely resolved.
