Olivier had contacted me after reading my blog (wow, people ARE reading this) to let me know about Solex, which is:
A Web application testing tool built as a plug-in for the Eclipse IDE. Based on a built-in Web proxy and a concept of extraction, replacement, and assertion rules (including regular expressions), Solex provides functions to record a client session, adjust it according to various parameters and replay it. This is typically done in order to ensure the non-regression of a Web application's behavior.
At first glance, it looks like a recorder of your browser interactions, so you don't have to repeat "click, click, click" over and over again to test some functionality. HttpUnit probably can accomplish the same thing, but you have to physically write code to test everything. Solex looks like it'll just record the test case. Looks cool to me, if I can find an hour to install and tinker with, I might even use it.
