Hi all
I was recently doing some application testing against WCAG 2.0 for a government agency here in Western Australia.  They asked me to test every page of their applications against the WCAG 2.0 criteria. The trickiest part was identifying the pages when they used the same URI.  I had to include a table with the paths or user tasks (e.g. if the user choose 'service a', then they would then be presented with 'scenario a' etc.)  Other than that, it didn't pose any different problems then assessing a normal website.  It just required lots of annotations of paths and actions.

Hi all,

Is there a suggested approach/procedure for sampling functionality
within an application, as we have for web pages within a website? Is
this usual practice that web accessibility evaluators take?

Best,
   Shadi
