Enzyme testing: mount vs render

Besides render uses "traversal library Cheerio"..

I've just replaced all my mount's with render's and it works the same.
They look similar to me.

What should I choose? Is API of those two is somehow not identical?
What are particular recommendations when to use render over mount?

Render doesn't need a global DOM to be available. So it allows the tests to be run outside of an environment like a browser. In your case, if your test cases were working before it would seem you are running the tests in a browser (since mount worked) and you wouldn't need to use render. If however, your tests were failing because there was no global DOM available, then render might be a good solution

Mount is FullDom rendering. Take a look at the official documentation for examples. From my understanding if you want to test lifecycle events such as componentDidMount you should use mount.
