JavaScript

For those of you who didn't already know: I'm writing a book. It's about JavaScript, it's about unit testing and it's about Test Driven Development. It won't be out until October this year, but drafts are already available through Safari Rough Cut.

Today I needed remote access to a gem I've been tinkering with for a while, so I pushed it to Gemcutter. It's called jstdutil, and it provides a small Ruby wrapper over JsTestDriver that adds colored output, a short, snappy `jstestdriver` command and autotest.

Since this summer, I've been test driving all my JavaScript code using Google's fairly fresh JsTestDriver project. If you're intrigued by TDD with JavaScript, including automatic testing (in a console, or - if you're a masochist - an IDE), test suites of 300+ tests running in 498ms as well as shiny red and green output, you should read on.

It's been quiet around here for a while. It's been quiet around Juicer, too. Both of those are going to change. After being given a push, Juicer is now finally up for some updates.

After switching my Ruby tests from vanilla Test::Unit to Shoulda (via Jeremy McAnally's Context) a while back I've gotten quite used to sexy unit tests. Coming back to JsUnitTest for JavaScript last night, I realized the syntac wasn't working for me anymore. So today, I fixed it.

For best performance, CSS and JavaScript should be served up using as few requests and bytes as possible. Juicer is a new command line tool that helps by resolving dependencies, merging and minifying files. It can even check your syntax, add cache busters to and cycle asset hosts on URLs in CSS files and more.

Most modern JavaScript libraries offer some kind of "dollar sign function". As another applied example of test driven development in JavaScript I'll walk you through developing your own dollar sign function.

With my two introductory posts on JavaScript testing under the belt, it's time to do some actual testing. In todays post I walk you through a pretty simple example in test driven development with JavaScript, coding a trim() function. The end result is presented with Qunit, jsunittest.js and YUI Test.

It's been a while since part one, but I guess late is better than never. In this second part I'll walk you through some available testing frameworks for JavaScript.

In a series of three articles I am going to walk you through the what's and why's of unit testing and test driven development focusing on JavaScript. We'll look into the underlying concepts, available frameworks for JavaScript, and of course a practical example to top it all off.
