Stress Testing with web service on ACT ( Please Help!)

A

Api

Hi

I've a web service which takes a big string as input parameter,
converts it to a text file and forwards it through FTP over to another
server.

Now I'm trying to stress test the web service through Microsoft's
application center test tool(ACT). I thought the no. of successful
requests which comes as output from ACT test report gives the no. of
successful calls to the web service. But somehow that number (no. of
successful requests ) does not match the no. of documents that were
forwarded to the FTP server. Also the web service is not generating
any error.

So I'm not able to find out from ACT how to determine the total no. of
successful calls made to the web service.

Is there any other tool that I can use over server, which will give me
the total no. of calls made to the web service during the test period
? If so what's the parameter I should be looking at. Or is there any
log over IIS that would give me the result?

I'm having a hard time to determine this. Please help me in this.

Thanks

Hi,

Have you thought about writing a small program that counts how many
error/non-error invocations are made. This should be calling the proxy for
the web service and setting the URL dynamically. I am not in a spot to
speak to the abilities of ACT to accurately log the numbers/failures. Is
it possible that there is a path thru your service that doesn't return in
failure but doesn't actually complete the FTP call? If you are calling
these in rapid succession, are you sure the FTP server isn't dropping the
requests? Have you verified that if FTP does fail that the web service
signals a failure back to the web service caller?

These are all thoughts that come to mind,

Hope it helps
