Official Google Angular testing guide

The main Angular testing guide is located here:

• https://angular.io/docs/ts/latest/guide/testing.html

You should probably read up to "Test a component with an async service". Please note that there are links to all live working examples near the beginning of the tutorial.

Adding PhantomJS into the mix

This is how to get the QuickStart project to work with Karma and PhantomJS.

Clone the repository

First you need to get the quickstart project:

$ git clone https://github.com/angular/quickstart.git
$ cd quickstart

Important: Obviously don't do this again if you already have it.

Install phantomjs and phantomjs launcher

First, you need to install PhantomJS, using a couple of npm commands:

$ npm install --save-dev phantomjs
$ npm install --save-dev karma-phantomjs-launcher

Change karma.conf.js

Once PhantomJS installed, you need to to Karma (the test runner) to use PhantomJS instead of Chrome (the default browser in the config file karma.conf.js):

// First change
// require('karma-chrome-launcher') 
require('karma-phantomjs-launcher')

// Second change
//browsers: ['Chrome'] 
browsers: ['PhantomJS']

Install Quickstart App

$ npm install

Run tests

$ npm test

TypeError: undefined is not a function error

If you get this error:

PhantomJS 2.1.1 (Linux 0.0.0) ERROR
TypeError: undefined is not a function (evaluating 'System.config')
at karma-test-shim.js:30

Append system-polyfills.js to karma.conf.js:

files: [
  // System.js for module loading
  'node_modules/systemjs/dist/system.src.js',
  'node_modules/systemjs/dist/system-polyfills.js',
