3A-TRE
3A-TRE evaluates traditionally logical expressions under 3 assumptions
... of the dependent test modules. In this case, the dependent test modules are always assumed to be true when their results are not available. We call this a stub assumption (SA).
3A-TRE example:
echo "CWA: (T and U)" | java -jar PTRE.jar
Result: F
3A-PTRE example: (P means possible results)
echo "OWA: (T,U and U,F)" | java -jar PTRE.jar
Result: U,F
