Oh cool :-)

I just noticed that selenium IDE has the option to export tests as PHP unit tests.

This is great - the IDE is a good way to interactively build up tests by recording a set of actions and tweaking what it records. 

And being able to save them as unit tests makes it easy to integrate this with automated testing.

Interestingly they are created as PHPunit tests - not simpletest tests.

As well as following standards such as those laid down by www.w3.org I always try and test websites I develop across a range of browsers. Despite improvements in compatibility in recent years, browsers do still vary in implementation and even relatively minor browsers are still used by large numbers of people.

However all this testing can be hard to keep on top of and sometimes I just have to push out what seems like a small code change with only limited testing.
