Horaa - Testing NodeJS Modules

With the recent development of NodeJS many developers who has worked with other languages starting to love NodeJS. But when they do testing It'll be quite hard for them because of NodeJS's module system.

Specifically, mocking existing( whether core or contributed ) modules will be very tricky. But with horaa it's fun to do that.

Install

npm install horaa

Example

Your Code

//stored in abc.js
exports.welcome = function() {
    var os = require('os');

    if(os.type() == 'linux') {
        return 'this is a linux box';
    } else {
        return 'meka nam linux nemei :)';
    }
};

Your Test Code (with horaa)

//stored in test.js
var horaa = require('horaa');
var lib = require('./abc'); // your code
var assert = require('assert');

//do the hijacking
var osHoraa = horaa('os');
osHoraa.hijack('type', function() {
    return 'linux';
});

assert.equal(lib.welcome(), 'this is a linux box');

//restore the method
osHoraa.restore('type');
