Document that react-test-renderer requires 15.3.0 (IE9+)

[LouisStAmour]

Just spent the last hour or so trying to get a basic example of react-test-renderer running with Jest and React 0.14.8. I figured since react-test-renderer required React 15.3.0, that the previous version of react-test-renderer, 1.1.0, would be fine but support React 0.14.8.

I was wrong. react-test-renderer 1.1.0 seems to be an entirely different beast, not meant to be used with Jest snapshots. The syntax is completely different, as currently documented at https://www.npmjs.com/package/react-test-renderer -- for example, it calls itself render, has no create method, and returns a bunch of query functions instead of a component.

So you might be wondering, why am I using 0.14.8 instead of 15.3? Well, it's simple. I still need IE 8 support. So I'm off to find another method for tests then... at least until IE 8 support isn't a requirement.

For Googlers, if you get the following error, it's because you're trying to use 15.3.0 syntax with 1.1.0:

  - TypeError: _reactTestRenderer2.default.create is not a function

I think it makes sense to assume that react-test-renderer and react will be published together and the same version of both should be used, just like for react-dom. I don't expect this to be an issue going forward and I believe your issue here is enough documentation now. Thank you for documenting it.

So I'm wondering where the doc for react-test-renderer@1.x exists?
