Mocha and ZombieJS

Question

I'm starting a nodejs project and would like to do BDD with Mocha and Zombiejs. Unfortunately I'm new to just about every buzzword in that sentence. I can get Mocha and Zombiejs running tests fine, but I can't seem to integrate the two - is it possible to use Mocha to run Zombiejs tests, and if so, how would that look?

Just looking for "hello world" to get me started, but a tutorial/example would be even better.

Thanks!

Assuming you already have installed mocha, zombie and expect.js according to instructions, this should work for you:

// Put below in a file in your *test* folder, ie: test/sampletest.js:

var expect = require('expect.js'),
Browser = require('zombie'),
browser = new Browser();

describe('Loads pages', function(){

    it('Google.com', function(done){

        browser.visit("http://www.google.com", function () {
            expect(browser.text("title")).to.equal('Google');
            done();
        });
    });

});

Then you should be able to run the mocha command from your root application folder:

# mocha -R spec

  Loads pages
    ✓ Google.com (873ms)


  ✔ 1 tests complete (876ms)

Note: If your tests keep failing due to timeouts, it helps to increase mocha's timeout setting a bit by using the -t argument. Check out mocha's documentation for complete details.

I wrote a lengthy reply to this question explaining important gotchas about asynchronous tests, good practices ('before()', 'after()', TDD, ...), and illustrated by a real world example.

if you want to use cucumber-js for your acceptance tests and mocha for your "unit" tests for a page, you can use cuked-zombie (sorry for the advertising).

Install it like described in the readme on github, but place your world config in a file called world-config.js

`/* globals __dirname */
var os = require('os');
var path = require('path');

module.exports = {
  cli: null,
  domain: 'addorange-macbook': 'my-testing-domain.com',
  debug: false
};

Then use mocha with zombie in your unit tests like this:

var chai = require('chai'), expect = chai.expect;
var cukedZombie = require('cuked-zombie');

describe('Apopintments', function() {

  describe('ArrangeFormModel', function() {
    before(function(done) { // execute once
      var that = this;

      cukedZombie.infectWorld(this, require('../world-config'));

      this.world = new this.World(done);

      // this inherits the whole world api to your test
      _.merge(this, this.world);
    });

    describe("display", function() {

      before(function(done) { // executed once before all tests are run in the discribe display block
        var test = this;
        this.browser.authenticate().basic('maxmustermann', 'Ux394Ki');

        this.visitPage('/someurl', function() {
          test.helper = function() {

          };

          done();
        });
      });

      it("something on the /someurl page is returned", function() {
        expect(this.browser.html()).not.to.be.empty;
      });

If you are using Microsoft Visual Studio, you might want to take a look at Rob Ashton's Zombify. Everything is acceptably integrated so you can start writing your test cases in JavaScript or CoffeeScript. By the way, learning CoffeeScript will take you like an hour, and it's worth every minute.
