[3.0.0-alpha.0 upgrade] can't resolve react-testing-library

[MohammedFaragallah]

Thank you very much for this alpha release i think it will be very helpful

after upgrading
react-admin => 3.0.0-alpha.0
@material-ui/core => 4.2.1
@material-ui/icons => 4.2.1

i got this error

ra-core/esm/util/renderWithRedux.js
Module not found: Can't resolve 'react-testing-library'

i tried to install it but i got another error

Error: 🚨 react-testing-library has moved to @testing-library/react. Please uninstall react-testing-library and install @testing-library/react instead, or use an older version of react-testing-library. Learn more about this change here: testing-library/dom-testing-library#260 Thanks! :)

I yarn add the react-testing-library@6.1.2 as a temporary solution

We should probably extract those test utilities in a separate package installable as a dev dependency

We already used react-testing-library in master. the difference is that we now export renderWithRedux, which depends on react-testing-library. So this package must be in dependencies rather than devDependencies in next. I'm marking this a s a bug.

Fixed by #3442

@fzaninotto When will this push to npm?

I got the following error and don't know if it is related:

Error in ./~/@testing-library/react/dist/index.js

You may need an appropriate loader to handle this file type.
