Enzyme: Warning: React.createFactory() is deprecated and will be removed in a future major release

[MutterPedro]

Current behavior

Hi all, today I updated my react project to v16.13, and now my tests that make use of enzyme helpers, began to give me this warning:

Warning: React.createFactory() is deprecated and will be removed in a future major release. Consider using JSX or use React.createElement() directly instead.

Expected behavior

Not showing the warning when using enzyme.

This is confusing - the only part of enzyme that looks at createFactory is inside our own tests, which you wouldn't be exercising.

Is there a stack trace at all? It's possible it's coming in from a dependency we use, or it's coming from an independent enzyme matchers package, or enzyme-to-json, or similar.

The whole stack trace is this:

/node_modules/react/cjs/react.development.js

Sorry, probably it is not enzyme fault, but I search in all of my testing dependencies and the only one that uses React.createFactory is enzyme... You can close this issue if you want.

Update, I found the guilty library, it is recompose which is a dependency of @material-ui/core that I am using in my components, so I guess I have to address this issue to material-ui.
