Max Horwath has published his slides on Making Selenium Test Writing easier using a DSL onlinefrom IPC 2008. Let me quote the whole short description:

Implementing automated tests by using Seleniums API methods has several drawbacks. Selenium is great for what it does, providing a generic framework for testing a generic application. Using the Testing_SeleniumDSL framework, I will show you how to create your own Domain Specific Language (DSL), which would allow you to write tests in the language of your business rather than in Seleniums language.

I'm quite impressed by the examples he presents, such as:

$this->assertThat($form->hasSelect(withName('statusConfirm'))->hasValues(),
    array('Yes','No'));

This is truly expressive, readable code. I've refactored web test code in this direction many times, but I admit I never got quite this far.

The DSL is planned as an open source release. It would be interesting to try something similar for the SimpleTest web tester, which is my favorite for testing web interfaces without too much JavaScript. (Based on the paparrazzi principle.)
