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.
Selenium is an application that allows automated testing of websites through a browser and consists of a number of different components. It allows the creation of browser tests that perform certain actions, which can then be run again at a later date. Three components are required to allow Selenium to run tests through PHP. These are as follows:
If you create classes in PHP then you should be unit testing them as much as you can. Setting up unit testing classes for your code can be time consuming and involve a bunch of copying and pasting. Thankfully, PHPUnit comes with a couple of helper functions that allow the creation of unit testing classes automatically, which can save a bit of copying and pasting.
As an example for this post I will use the following Spider class, which is part of some code I am working on at the moment to create a simple site spider in PHP.
PHPUnit is a unit testing framework, written in PHP, and which is used to test PHP code. You can integrate the testing that PHPUnit does into Phing. You might want to use Phing to create a nightly build that contains the latest version of your program. The last thing you want is Phing to create a nightly build that is riddled with errors.
The way around this is to use PHPUnit to test our code whilst we are running Phing. If any tests fail then Phing will not finish the build.
Create a target at the top of your build.xml file and make sure it is run first. Then add the following code to the target, This will use PHPUnit to test your code.
