yeah, I just got a test working for JMeter in like two minutes. that's pretty cool.
You don't 'have' to write a test for every single method and jsp if you use JUnit.
Thing is, I need something that will handle JavaScript correctly, not just a pre-defined post or get. and it seems that HttpUnit handles this nicely with Mozilla's Rhino (JavaScript for Java). that's cool. I'm still looking into it though....
