At the TA level it is all part of the test. A condition being met or not is just a test carried out in order to determine the test outcome. If the > conditions are not met in an overall TA the TA is inconclusive. I disagree with that. If some interim test, internal to the defined TA/TEST fails, then it is likely that the entire TEST fails. There are generally only two options. Pass and other. Anything other than a full pass is by default a TEST fail. I'm using UC for the TEST as an entity. It may be implemented as 480 lines of code, but together it implements a TEST as agreed with the design authority. I'm using a definition of TA as this level of TEST. > So maybe we can define how a whole TA Not until we agree at what level of abstraction the TA relates to a test (or TEST as I've used it above :-) reaches results of pass, fail > or inconclusive.

No other choices, else go back and re-define the TEST! > Can a TA overall evaluate to true/false or is it always going to be > pass/fail/inconclusive (inconclusive being an outcome of conditions > not being met on certain steps)? Just pass and fail. Why has it failed? See the test results. regards -- Dave Pawson XSLT XSL-FO FAQ. http://www.dpawson.co.uk
