Validate props on context providers #12658

wherestheguac · 2018-04-20T03:36:28Z

Description

Prop types aren’t being checked on context providers, resulting in no dev warning in situations like the following:

References issue: #12636

Changes

Added checkPropTypes call to updateContextProvider
Added a test to make sure prop types are being checked on providers

Notes

I only added one test as I thought multiple tests with different propType specification would just be testing the underlying prop-types library instead of react. If this needs to be moved or I’ve missed something let me know! 😄

Let’s call this Context.Provider

This is missing the component stack argument. Can you please add it, similar to how we do elsewhere?

I think you can use getCurrentFiberStackAddendum similar to how we do in ReactDOMFiberComponent.js.

Ahhhh I meant to do this after I was done testing it and completely forgot, I’ll get on that tonight!

Let's only call checkPropTypes if workInProgress.type.propTypes exists. Read it before the call and then, if it exists, call the function, passing it as an argument.

@gaearon fixed those issues 😃

Could you please split this into two nested conditions? We try to always keep if (__DEV__) { as a separate block to make it very distinctive.

Please include stack in the expected message. You’ll want to use ** placeholders similar to other tests that assert about the warning with stacks.

I’m having a bit of trouble finding an example of this in the tests. Potentially just not sure what I’m looking for. Do you know of one that uses this?

@nicolevy you can find an example of what Dan means here: https://github.com/facebook/react/blob/master/packages/react/src/__tests__/ReactContextValidator-test.js#L182-L183

getStack would only ever be called in DEV, so we can pass getCurrentFiberStackAddendum to checkPropTypes directly and avoid the getStack variable altogether.

Please move this right after imports so we only do this once. You can check how we do this in other files.
