Automating Headless Selenium PHPUnit Tests

15th January 2013 - 7 minutes read time

I have talked before about running Selenium tests in PHPUnit but I have only recently come to properly automate things. Getting a Selenium server to start and stop in a script is relatively easy and can be done in a simple script. My original script for running a directory of PHPUnit tests was as follows. I will explain more about how this all works later on in this post.

Getting Started With PhoneGap And Android

4th January 2013 - 7 minutes read time

PhoneGap is a free and opensource framework for developing mobile applications. It is a great way of creating applications that work across multiple devices including iOS, Android, Blackberry, Windows and others. It works by rendering HTML pages using a browser, which means that you can create applications using just HTML and JavaScript. It also allows you to interact with elements of the phone like the camera and accelerometer through JavaScript using a simple API.

I recently set about trying to use this system to create an application, and as I have an Android phone I started by creating a simple Android app. The PhoneGap website has a number of getting started guides, including what software you need to get started. I found that they were a little wrong for getting started in Android. I am running OSx so the instructions here might not work for you, but they should be fine for most *nix based systems.

Drupal Homepage Takeover

7th December 2012 - 2 minutes read time

I had a recent requirement where I needed to temporarily replace the homepage of a website running Drupal with a simple HTML page. I wanted to do this without doing lots of changes to the site templates so I needed a solution that was easy to turn on and off and would still retain the Drupal site as it was. I found the simplest solution was to add a rule to the DirectoryIndex rule in the sites .htaccess file. Here is the rule I used.

Storing Automated YSlow Tests With Show Slow

3rd December 2012 - 8 minutes read time

I was at a meeting of the Manchester Web Performance Group the other day where Tom Taylor gave a talk about some of the performance testing tool he uses at Laterooms.com. He used a ruby script to set up some preferences in Firefox which then ran Selenium to open some web pages and test them with YSlow. The results of the YSlow inspection are then sent to a Show Slow server where the results can be graphed over time. I realise that I've just mentioned a whole stack of technologies there, so let me pick out the important ones:

Selenium is a remote control agent for web browsers, although it is most stable in Firefox. I have written about this tool before but it allows us to automate interaction with a website via a series of selenium scripts. These scripts can be exported into different code formats, including PHP.

DrupalCampNW 2012: A Review

2nd December 2012 - 14 minutes read time

When Mike Bell approached me several months ago and said we should do a Drupal camp in the north west I was completely on board with the idea. So for the past few months I have been working with Mike and a group of people from the North West Drupal User Group (NWDUG) to create such an event. The result was DrupalCampNW2012, which was held from Friday 23rd to Sunday 25th November. The venue was the new University of Salford campus buildings in MediaCityUK.

Our main stumbling block in getting this conference up and running was the venue. After talking to some of the computer science people in the University of Salford they offered the use of the building in exchange for some free student tickets.

Playing With ReactPHP

19th November 2012 - 14 minutes read time

I recently saw an implementation of a Twitter wall that used node.js to run searches on Twitter and post the results on a webpage. I had been wanting to create something using ReactPHP so I thought this was a good opportunity to have a go. ReactPHP, if you haven't heard of it, is an event-driven, non-blocking I/O that is essentially the PHP equivalent of node.js. The major difference is that ReactPHP is written in pure PHP with no extra components, whereas node.js is a collection of different programs, interfaces and languages. As a first attempt I wanted to create something simple so it needed to use simple JavaScript to load in the latest tweets for a given hashtag from a ReactPHP server. I have to warn that this is a simplistic implementation of ReactPHP, but it shows the basics of how to get started.

Changing Submit Input Elements Into Buttons In Drupal 7

16th November 2012 - 6 minutes read time

I spent what seemed like an eternity today trying to figure out something in a form I was creating on a Drupal site. I was building a multi step form with previous and next buttons, both of which were submit elements like this.

Creating Mac OSX Aliases

10th November 2012 - 4 minutes read time

Adding an alias to your system is a good way of saving time when remembering complex commands. You can reduce a command down to a quick two letter command that is easy to remember.

The alias command can be used to assign an alias on the fly. You can create an alias to 'ls -lah' by typing in the following into the command line.

alias ll="ls -lah"

Now, when you type 'll' (i.e. two lower case L's) you will actually run the command 'ls -la'.

Or you might want to do more complex things like running your selenium server.

alias selenium-server="java -jar ~/Development/selenium-server-standalone-2.25.0.jar"

To remove an alias you can use the unalias command to remove an alias from your system.

Checking Syntax Errors In PHP And JavaScript Using Phing

Checking Syntax Errors In PHP And JavaScript Using Phing

Running a simple syntax check over your files is a good way to save time. This can be when testing code but best practice is to not to even commit code that contains syntax errors.

You can syntax check a single file using the -l (lowercase L) flag with the PHP executable like this.

$ php -l file.php

Unfortunately this can only check one file at a time so I set about trying to find a good way of checking a whole project at once. There are a couple of scripts available on the internet, but I set about creating my own solution using the phplint task in Phing. This means that I can just create a fileset and feed this into the phplint task without having to rewrite the whole thing if I wanted to include (or exclude) a particular directory or file.

Happy Birthday Bash Script

29th October 2012 - 1 minute read time

Following on from the PHP script to print happy birthday I wanted do the same in a bash script. I don't really use bash for much more than stringing together commands so I had to figure out how to do loops and if statements using the simple bash syntax. I also wanted to pass the name of the person as an argument, rather than hard code it into the script. This is what I came up with.
