Mocha, using this.skip() to skip tests dynamically doesn't work

Question

I'm trying to skip tests if a condition returns true using this.skip() inside an "it", but I'm getting an error "this.skip is not a function". this is the simple code I'm trying to check it on:

var async = require('async');
var should = require('chai').should();
var chai = require('chai'),
should = chai.should();
expect = chai.expect;
chai.use(require('chai-sorted'));

describe('Testing skip...\n', function() {
        this.timeout(1000);
        it('test1', (done) => {
            this.skip();
            console.log("1")
            done();
        });

        it('test2', (done) => {         
            console.log("2");
            done();
        }); 

});

I installed "mocha@5.2.0 " since I saw it only works on since "mocha v3.0.0", but I still cant get it to work, and none of the past discussions on the subject seems to fix my problem.

in order to use this in mocha, don't use arrow function. So, in your code you need to write it as

it('test1', function(done) { // use regular function here
  this.skip();
  console.log("1")
  done();
});

The best practice in Mocha is to discourage arrow function as described in https://mochajs.org/#arrow-functions

Hope it helps

Slip up on this a lot. There's an eslint plugin for this. https://github.com/lo1tuma/eslint-plugin-mocha/blob/master/docs/rules/no-mocha-arrows.md – Dan Caseley Sep 21 '18 at 07:25
