React - how to write tests so that the linter likes them?

Question

Software testing

Starting to use Jest + Enzyme in react apps.
Wrote a test as in the example, linter (eslint) does not like a lot of places:

What is the best thing to do? Disable linter for test files? Write tests differently somehow?

Answer 1

You need to tell the linter that some globals.
Try to specify something like this in the eslint config for tests:

"env": {
    "jest": true
}

Or

"env": {
    "jest/globals": true
  }
