How To Make Sure 'this' Inside Mocha Test Have Access To Class Properties

const expect = require('chai').expect; class Test { constructor(){ this.x= 10;} run() { describe('test goes here', function() { it('sample test', function() { expect(this

Solution 1:

Use arrow functions () => this... or .bind on your functions.

describe("test goes here", () => {
  it("sample test", () => {
    expect(this.x).to.be.eq(10);
  });
 });
