Stub out module function

Question

Edit: Being a little bit more precise.

I want to test usecases for a Github API wrapper extension, that our team has created. For testing, we don\'t want to use API wrap

Simplest solution is to refactor your module:

instead of this:

module.exports = function(args, done) {
    ...
}

do this:

module.exports = function(){
    return module.exports.github.apply(this, arguments);
};
module.exports.github = github;

function github(args, done) {
    ...
}

Now you can require it with:

const github = require('../services/github.js');
//or
const github = require('../services/github.js').github;

To stub:

const github = require('../services/github.js');
let githubStub = sinon.stub(github, 'github', function () {
    ... 
});
