How to properly require modules from mocha.opts file

Question

I\'m using the expect.js library with my mocha unit tests. Currently, I\'m requiring the library on the first line of each file, like this:

var expect = require

While Louis's answer is spot on, in the end I solved this with a different approach by using karma and the karma-chai plugin:

Install:

npm install karma-chai --save-dev

Configure:

karma.set({

    frameworks: ['mocha', 'chai']
    // ... 
});

Use:

describe('something', function () {
    it('should pass', function () {
        expect(true).to.be(true); // works
    });
});
