Hi Elle, Peter & list,

I can think of scenarios where an evaluation proceeds without  
knowledge and consent of the site owner - for example where user  
advocates want some evidence to shame providers into making more  
efforts to be accessible. That's why we tested Facebook last summer.

Here, the use context clearly suggested some important use cases which  
we picked accordingly: registering, changing profiles, and 'finding  
friends'. Obviously, a lot more could have been picked but you have to  
draw the line somewhere. It was tricky though to document all the  
dynamic states, particularly as some cannot easily be rolled back and  
require logout/ new login. So it was quite a difficult test (three in  
all, actually, for the aforementioned use cases). I think  
unfortunately it will never be easy to evaluate such complex processes  
with generated states...the question for us is what can be tied down  
in the evaluation methodology and what needs to be adapted/decided per  
case.

Regards,
Detlev
