A Controlled Experimental Evaluation of Test Cases Generated from UML Diagrams

This paper presents a single project experiment on the fault revealing capabilities of test sets that are generated from UML statecharts and sequence diagrams. The results of this experiment show that the statechart test sets do better at revealing unit level faults than the sequence diagram test sets, and the sequence diagram test sets do better at revealing integration level faults than the statechart test sets. The experimental data also show that the statecharts result in more test cases than the sequence diagrams. The experiment showed that UML diagrams can be used in generating test data systematically, and different UML diagrams can play different roles in testing.
