New tinderbox tests for sunbird/lightning

For the calendar project, there are tinderboxes creating builds. Firefox 
have Ts, Txul and tests like that. But nothing exists for calendar code. 
I'd like to add those somehow. The question is: what would be the best 
way to do that? I don't really know any tinderbox code, but from a first 
look, the test-suite didn't look extedable. The tests are pretty much 
hard coded. Is there some way around that? Is it possible to add new tests?

I'm currently thinking of a testrun that would look like:
sunbird -createprofile perftest
sunbird -P perftest -measurestartup <current time>
sunbird -P perftest -subscribe <url to some ics file>
sunbird -P perftest -measurestartup <current time>
and maybe a few more. The pattern is that I try to make it all 
scriptable from the commandline. But how do I get tinderbox to run that?

Can Talos help in any way?
