I apologize for having very little documentation for HTTPTest (I'll  
be writing it next week) so I'll try to explain this a bit better.

HTTPTest was written after I wrote the original proposal for the new  
framework so it's written with the that framework in mind. I looked  
at other test tools before I went off and wrote my own and found that  
the simpler things I HAD to have weren't in them so I decided to  
quickly write my own.

HTTPTest grew fast and I added a lot of features in a short amount of  
time and had to stabilize it so that we could depend on the output.  
HTTPTest inherits from another tool I wrote as a micro test framework  
called TestObject. TestObject is simple but it is still pretty  
feature rich with support for; multiple debugging levels, multiple  
output masking levels, and support for a threaded stress testing  
system. Even after the new framework is done I intend to keep  
TestObject functional and HTTPTest will continue to support it and  
the new framework.

I think I need to reiterate my main point. I don't think that we  
should be certifying releases with, or bundling releases with, tools  
that are not up to release quality. The main problem with homegrown  
test tools is that people tend to not trust the integrity of the  
testing, and sometimes look at the test scripts and tools as the  
problem before believing it may be a bug in the product. The same  
thing would occur with unittests if we even used an unstable unittest  

Previously it was unfeasible to have the requirement that releases be  
tested with release tools developed at OSAF. It's now feasible for  
cosmo and scooby and I would like to move in that direction. I don't  
view the issues associated with it as a burden because I think it's  
the _right way_ to do things.

The original spec is up here (http://wiki.osafoundation.org/bin/view/ 
Projects/OpenAutomationFramework). Note that it is very chandler  
focused because it pre-dates the existence of our cosmo and scooby  
test tools and our new move towards the eco-system.

What I need to update in this spec is the major requirement that the  
framework support distributed testing, which I will update as soon as  
I go back to working on the framework. This framework is very  
ambitious and immediate needs have superseded a lot of it's  
development, but soon I'll start increasing it's priority.
