Error: It looks like you called `mount()` without a global document being loaded

Question

I'm trying to mount a component for testing with enzyme, and get this error.

Answer 1

npm install --save-dev --save-exact jsdom jsdom-global

Then:

import 'jsdom-global/register'; //at the top of file, even before importing React

More info here.

Alternative: In case you are using jest with enzyme-

In your package.json, specify the test environment for jest as jsdom as follows:

"jest": {
  "testEnvironment": "jsdom"
}

I faced the same issue and it worked well for me.
