As a web development manager, it’s part of my job to be involved in defining best practices for my team. This means defining a set of standard practices that will benefit the whole team throughout the entire development process. A good example of one such best practice would be code testing.
Testing, for web developers, is usually a fairly disorganised affair. Most of the time, we test “on the job”, i.e., we code something and then we run it; if it breaks, we fix it. In fact, often, the thought of actually structuring our testing process can seem somewhat of an over complication. This is certainly not the case.
The benefits of a structured testing process are legion, as any software engineer will attest. At the very least, it provides confidence in our code – something which can only be of incredible benefit when code is shared across a wider team. At its best, the tests we write can influence the way we develop the code being tested; and save effort, time, and money.
In this post I’m going to look at “unit testing”, and how it can be of benefit to web developers in general.

I noticed last night that Google had acquired Feedburner, and that I needed to port my feed over to my Google account. At the same time, I swapped the feed to use Atom instead of RSS. Having completed that, I decided to address a problem with my feed that’s been bugging me for some time:
My feed has always published only an excerpt of each post, instead of the full post. This is because I use the “more” break functionality in Wordpress for the introduction snippets in the bespoke home page theme files, instead of writing an entirely separate excerpt. On previous versions of Wordpress, this also limited the RSS feed regardless of whether you had specifically chosen the “display full article” option in the syndication settings. I’ve had a couple of complaints about this, since most developers seem to prefer reading articles in their feed readers – and so do I, for that matter.
Last time I needed to fix this problem, I had a hell of a time trying to find the offending code in the horrific Wordpress PHP. Thankfully, since then, the bug has been fixed so all I needed to do was update Wordpress. Having completed that update, my feed should now be working as intended originally.
The next step, it seems, will be getting off Wordpress to something home-grown.
When I first began developing using a Mac I made use of the bundled versions of Apache and PHP that were included in OS X Tiger. This meant I only needed to install MySQL to be able to develop fairly complex websites.
However, as my requirements evolved, I discovered that recompiling PHP to include support for features such as HTML Tidy was going to be a pain in the proverbials. So, following advice from friends, I opted to install another version of Apache, PHP5, and MySQL using MacPorts package management. This required minimal configuration and allowed me to easily activate or deactivate features on install – and it also allowed me to add to my environment as I learnt new skills; including Python and Django.
Recently, however, this became an issue again, as I attempted to install mod_wsgi in the MacPorts Apache. No matter how hard I tried, I just couldn’t get it working with more complex Python scripts. At this point, I sought more help from my friends and, after a couple of attempts to rectify the problem, was suggested the movement of my entire development environment to a dedicated virtual machine.
So, thanks to Danny Amey and Brad Wright, I’m now running a proper Ubuntu server as my development environment and have just as much control over it as I do on my live web server. In fact, the two are pretty much identical; and, best of all, I have access to all the files on my dev server using VMWare shared folders, which means I can use all my favourite OS X tools to create and edit files. I really can’t advocate this method enough.
For more information on creating such an environment, I recommend reading Brad’s post, ”development virtual machines on OS X using VMWare and Ubuntu”.
Setting up web servers is an oft-covered subject in the web development blogosphere. However, when I needed to set up a shared web and email server, I discovered that such documentation was somewhat more dispersed. With that in mind, and following the development of an email newsletter at work (in which I demonstrated several email testing techniques that were of interest to some of the other developers), I began drafting a blog post that would hopefully bring some of that information together. Sadly, I never finished.
Due to an ever more stressful workplace and the arrival of another child in the household, I took a somewhat forced break from blogging. This was entirely unintended and I’ve decided to get back on the wagon again by finishing the aforementioned post.
So here it is; the finished article on setting up Postfix on a shared mail and web server. Please remember that I’m technically a mail server numpty and probably won’t have all the answers to questions should you have them. However, feel free to leave them in the comments and hopefully someone out there (or someone I can poke for comment elsewhere) can help you out.

I’d prepared for this daring feat of code-ninjutsu [yes, that’s the correct spelling] with a crash course in Python via ”Dive Into Python”, by Mark Pilgrim.
This appears to have been the correct choice, as I’ve already acquired a confident grasp of the concepts and techniques of Django in less than a few days of playing with it (granted; with the odd reference look-up on http://www.djangobook.com/ and http://docs.djangoproject.com/en/dev/).
However, last night it all went a bit wrong when I upgraded my local version of Django from 0.96 to 1.0…
