Mocha tests: Missing function expression name. (func-names)

When writing Mocha tests, it is not possible to use fat arrow functions because we sometimes need to use the this keyword to change the test’s timeout for example.

describe('some description', function () {
  before('blabla', function () {
    this.timeout(10000);
    return somePromise();
  });
});

This results in the following eslint error:

Missing function expression name. (func-names)

I was wondering what was the guidelines for this case. Naming the functions is out of the question as it would add a lot of noise.

Using arrow functions in mocha tests is discouraged according to their official documentation.

I just don’t really see the point for mocha tests and it goes against the DRY principle. e.g.

    it('should return status 200', function shouldReturnStatus200() {
      expect(self.res.status).to.equal(200);
    });

Anyways, I added func-names: 0 to my tests/.eslintrc.
