I have never really done any serious testing other then writing some simple Java unit tests at University. I want to try and get into the practice of testing so I want to start small on this simple website that I am currently developing.

The site is built using [CodeIgniter](http://codeigniter.com) and doesn't really do any dynamic things other then the contact form logging what has been entered into a database.

I have written two unit tests for this controller using [TOAST](http://jensroland.com/projects/toast/) which test the contact model's insert and retrieve functions which you can see on [pastebin](http://pastebin.com/n9cJjUrA).

What other testing practices would you recommend and what could be applied to such a small web application?
