I finally got to mess around with PhantomJS and Jasmine, and couldn’t find a resource that gives clear, concise, accurate information, without language specific or build tool specific coupling, so I decided to write it myself.
Fortunately, it is way simpler than I thought.
PhantomJS is a standalone, cross platform command line application which does not require any specific server environment or programming language support.
In my previous post, I covered the structure of a Backbone.js application using RequireJS.
The next thing (or if you are a TDD fan, the first thing) we do is to run some tests on it.
According to Coda Hale:
Writing tests for your code may not reduce the number of bugs, but it will make fixing the bugs you inevitably find easier.
Obviously, we can take advantage of the AMD architecture, to help us write modular tests (or “specs” in the BDD language).
To get a better sense of the challenges and different approaches in unit testing, I wrote the exact same tests three times using three different testing frameworks: Jasmine, Mocha and QUnit.
