I’ve download the webpagetest source code.I’ve read it for a few days,but still confused…
There are a lot of things:winpcap, wptdriver, wpthook…
Where can I find the source code explaination or structure. I’am soooo confused…:huh::huh:
Thanks a lot…
The code isn’t for the faint of heart and the structure isn’t really documented all that well. The project is basically split into 2 trees:
The Web UI - trunk/www/webpagetest (pretty much all php with a little python support for mobile)
The test agents - trunk/agent
The agents are pretty complicated but basically break down as:
IE:
browser/ie/Pagetest.sln - main solution file for visual studio 2008 SP2 that builds everything
browser/ie/urlblast - controller that drives the IE testing
browser/ie/pagetest - browser plugin that does all of the instrumentation for IE
Chrome/Firefox:
webpagetest.sln (at the root of the tree) - main solution file for visual studio 2010 sp1 that builds everything
wptdriver - controller that drives Chrome/Firefox testing (with experimental IE support as well)
wpthook - cross-browser API interception that is code-injected into the browsers and does all of the measurement (equivalent of pagetest)
browser/chrome - chrome extension for some browser-specific functionality
browser/firefox - firefox extension for some browser-specific functionality
