Web Performance testing using VS2010 "Testing a file download"

Question

Hi All,

I am trying out the VS 2010 testing tools for the first time. And I tried recording a web performance test and my actions had a file download implemented as in the KB article here http://support.microsoft.com/kb/812406 by streaming chunks of 10000 bytes.

However my test is failing at the download saying "The response stream has been closed".

Please help me understand why it is happening this way also any suggestions how you would test such a file download.

My main aim was to see how the download was performing for a load test with Intercontinental 350kbps connection on files of about 30-50 MB.

Thanks.

Answer 1

pretty much the same problem here. Fiddler picks up the request, and I tried manually adding it to my web performance test with no luck.

Does it work in a real browser? If so, you can use iMacros for IE/Firefox to test file downloads. You can integrate iMacros via the command line into your testing scripts. We automate many downloads with it. The free/open source iMacros versions is sufficient for download automation.

As an added benefit, you test your site and downloads in real web browsers.
