Stephen:

 

I agree with the need to support "TA negation" in prerequisites. Have seen this before.

Given that the outcome of a TA is 3-fold:

- predicate=true

- predicate=false

- not applicable

 

We may need to be more specific. In this precise case, instead of saying

Prerequisite: NOT widget-TA103-1

 

I woudl write:

 

Prerequisite: (widget-TA103-1 = "false")

 

Which is not quite the same as the following valid prepreq expression:

 

Prerequisite: NOT (widget-TA103-1 = "true")

 

The end result is that in any case, the prereq expression is still a boolean expression. Only, it should acknowledge the different possible outputs of a TA used inside.

Note:

This update includes changes made on wiki as shown here

http://wiki.oasis-open.org/tag/TestAssertionGuidelines?action=diff&rev2=239&rev1=233

Please also note changes and new test assertions in Worked Examples appendix.

Especially note an interesting feature I came across which is the need, it seems,

to accommodate negated TA-reference prerequisites.

(Another more straightforward TA is also included with a positive prerequisite ref to a TA.)

Negated prerequisite seems to be required as follows:-

Normative Source:

Section 102:

It is RECOMMENDED for a widget to be waterproof. If it is not waterproof then it MUST have a warning label stating that it is not waterproof.

TAs:

TA id: widget-TA102-1

Target: widget

Normative Source: specification statement 102, part 1

Predicate: [the widget] is waterproof.

Prescription Level: preferred

TA id: widget-TA102-2

Target: widget

Normative Source: specification statement 102, part 2

Prerequisite: NOT widget-TA103-1

Predicate: [the widget] has a label warning that it not waterproof.

Prescription Level: preferred
