Subject RE: Stress Testing of a Servlet using Cactus !!!
Date Thu, 23 May 2002 19:35:47 GMT
Ravi,

Cactus is *not* about stress test as it is; It is about unit testing
code (white box style). 

Extensions for using Cactus as stress test would be possible I guess. It
might even be very useful as it is nice to be able to stress test
portions of the site from the inside as opposed to stress testing from
the outside which doesn't help you understanding what is wrong inside.

I am open to suggestion and patches for that. Actually I would view that
as an extension. If someone wanted to start such a project, we could
certainly create a proposal/ directory in Cactus to work on that and see
how it works out.

Thanks
-Vincent

P.S.: Try JMeter for stress testing at the level of HTTP (not at the
level of Servlet code).
