We use PreVue, the network traffic simulator from Performance awareness
and it does a great job. We run HTTP, FTP, TELNET, SMTP, POP3, etc..
some things it doesn't like to do directly from our PreVue machine, but
we've recorded scripts to telnet to another box and to do it on an
application level.
Also, for automated client side testing, in the past I've used the
WindowsWare WIL script language. I have a script that will open X # of
FTP sessions on a windows 95/nt box (a 486/100 with 32 megs was doing 40
concurrent FTP sessions no problem, just had 5 of those machines going
to give us 200 concurrent connections).
I did the same for HTTP by using WIL to send a DDE call to Netscape
telling it to open a specific URL and then saving the file it was
receving to different incremental filenames. I still need to work out a
few bugs in that script though.
We may be ordering the compiler for the WIL code, if so I might consider
making the compiled versions of these tests available to the public.
But between WIL scripts (a cheap and easy automation solution) and
PreVue, we have all of our bases covered.
Anyway has any questions about either of these, drop me a line.
