Nike’s slogan is the only one fit for the issue I’m about to raise in this article: Unit testing. Deep down, everyone knows the benefits from unit testing your code. Unit testing can give you that warm feeling when you go to bed, knowing that the changes you made, didn’t break previously working code. It makes you happy and it gives you confidence.
Yet, a lot of us (including me) don’t actually start unit testing our code. There are a number of reasons for that, but I’ll have none of that now. Because now, I’m going to show you just how easy it is to unit test your Javascript. I’ll be using QUnit, made by John Resig, creator of jQuery. Even though I’ve just begun using QUnit, the code I presented in my previous three blog posts, has really benefitted greatly from it.

In this final part of the series, I’m going to create a Publish/Subscribe provider for my new framework. With this so-called pubsub provider, it will be possible for any function to create or fire an event. Any other function may then listen for that event, and will get triggered when the event occurs. My main goal is to make sure that this provider is easy to use, not only for plugins, but also for regular functionality. Besides that, I also want to have my code as loosely coupled as possible. For that, I’m going to use a little bit of Dependency Injection + lazy loading. All this to make sure that plugins are as agnostic as possible about the outside world.

In this second installment of my 3-part library-building journey, I’m going to make the core plugin for the library. This plugin will contain utility methods. Stuff that can be used, either by other plugins, or just by regular Javascript code. So far, I haven’t needed many utility methods, so this chapter will be rather short. If you’re ready, read on!

Goal
There are two programming languages I like: PHP and Javascript. In this mini series, I will explore Javascript and jQuery, and build my own library/framework. I won’t re-invent the wheel here. I’ll just make a collection of methods and functionality I need, making use of some functionality in jQuery.
The goal of the first part of my mission is to create a small, lightweight, self-contained, easily extensible base for my framework. Recently I created my own little company, called “The Analog Guy”. I’ll just call my library “TAG”.
