Mixed rendering is a mode that works like shallow rendering, but where you can specify a list of components you want to render even tho they are deeply nested.

Needs to use indexOf()!==-1 because this lib supports IE9+.

This file is size-constrained - would it be alright to add the alwaysRenderedComponents option, but not export another method (mixedRender)? That would keep things reasonably minimal.

@developit I've updated the PR, but kept the unit tests in a separate file. Do you want me to move them as well? |

Hi @Saegrov! Sorry for the delay - happy to have the unit tests in their own file. I think this should be good to merge, just need to check the file size. |

Mixed rendering is a mode that works like shallow rendering, but where
you can specify a list of components you want to render even tho they
are deeply nested.
We have a use case where we are using shallow rendering and Cheerio for unit testing our Preact components. We are using a redux-connect like higher order component to connect some components to our global state.
When testing a component, that uses another component that is wrapped in a HOC, the shallow renderer stops at the HOC.
With mixed rendering we can white list components we want to render and test that the wrapped components are used correctly.
