<quote> Pass: the condition for adherence is satisfied (or is “true”) ... Notes: - A test assertion may specify condition(s) for pass alone, or for fail alone, or for both. </quote> Is there an example of a TA for pass alone? I imagine most concerned with pass will also cover fail as the opposite of pass won't they? <quote> - If the adherence condition associated with a pass outcome is not satisfied for an IUT (i.e. it evaluates to “false”) this does not cause a fail outcome. </quote> I guess this is the statement which Dave points out could be laughed at a bit. Fair enough if it is not thought about too much but, still, if the TA is for pass alone then this statement is necessarily true. I think there's a problem believing there are TAs for pass alone which is why it seems a bit laughable. Perhaps the Note should also cover the easier to understand type of adherence condition which is associated with both a pass outcome and a fail outcome. How about adding it at the beginning (with a bit of rewording)? "Notes: ... The adherence condition may simply be associated with a pass outcome and also cover the fail outcome such that if the condition is not satisfied for the IUT (i.e. it evaluates to "false") this will cause a fail outcome, as expected. However, if the adherence condition is associated with just a pass outcome and not the fail and is not satisfied for an IUT (i.e. it evaluates to “false”) this does NOT cause a fail outcome. Conversely, if the incompatibility condition associated with just a fail outcome is not satisfied (i.e. it evaluates to “false”) this does not cause a pass outcome. ..." I think examples would be clearer though than just stating these things as (in some cases apparently unlikely) facts in the Notes. We'd especially need an example of a condition for a pass alone but one for a fail alone seems more likely to be typical. I think I agree now with both Dave and Lynne if I understand it rightly that most existing TA examples will be for a pass but will also include (perhaps implicitly) a fail and I think the fail might tend to be associated with a false condition in most existing TAs. Maybe there is some change management needed... Regards Steve
