thank you for providing such a great tool!
I was tested the same URL by IE8 and firefox,then I compared the result in the xmlResult file. I found that something were diffrent from each other.
Patrick,thanks so much for the response.
But, why it hasn’t been implemented in the Chrome/Firefox agent? Is it a bug, or what can I do to make it correctly?
I set up a private instance, and the same error happened neither…
It hasn’t been implemented “yet”. It’s on the todo list but there are a fair number of features in the legacy IE agent that just haven’t been implemented yet in the newer agent (you’ll notice that Page Speed isn’t integrated either for example).
Process for actually contributing code or system architecture/process?
For contributing code you email me patch files and then after I’m comfortable that you’re comfortable with the code you can get commit rights.
As far as the system itself goes, there are some exceptionally-high-level diagrams here: https://sites.google.com/a/webpagetest.org/docs/system-design/overview with a lot of todo’s to create more docs. If there’s a particular area you’re interested in just let me know and I’ll force myself to start creating the docs
