Typescript-react-starter: ReactTestUtils Warning

[samblake]

When running tests as described in the readme I get the following warning.

ReactTestUtils has been moved to react-dom/test-utils. Update references to remove this warning.

To fix this I added a dependency on react-test-renderer as required for Enzyme with React >= 15.5.

Hey @wmonk, would it make more sense to add this to the https://github.com/wmonk/create-react-app-typescript repo?

We just upgraded to [email protected] so might have been fixed in there. Nobody else has opened this issue there, but if it persists feel free to!

@samblake can you try again and see if the issue is still present?

[samblake]

I tried again, seems to be fine now.

[samblake]

Sorry, got trigger happy, the problem is still present.
