UCTSystem is a prototype tool designed to perform automatic test generation from UML requirements. It uses UML use cases enhenced with contracts (i.e. precondition and postconditions) to build an execution model allowing all valid sequences of use cases. Using this execution model and several test criteria, it generates test objectives as sequence of use cases to exerce. It includes both criteria for functional testing and a criterion for robusness testing. Those test objectives are then mapped into test cases using test templates.

113-126(March 1976)p. 116:
"The Physical Symbol System Hypothesis. A physical
symbol system has the necessary and sufficient
means for general intelligent action."
p. 120:
"Heuristic Search Hypothesis. The solutions to
problems are represented as symbol structures.
A physical symbol system exercises its intelligence
in problem solving by search--that is, by
generating and progressively modifying symbol
structures until it produces a solution structure."
p. 121:
"To state a problem is to designate (1) a test
for a class of symbol structures (solutions of the
problem), and (2) a generator of symbol structures
(potential solutions). To solve a problem is
to generate a structure, using (2), that satisfies
the test of (1).".
