Rational QualityArchitectis a powerful system testing extension to Rational Rose®. It automatically generates test drivers and stubs from UML models to support functional and performance testing of EJB and DCOM/COM+ components and subsystems. QualityArchitect improves software robustness and predictability by validating software quality early in the life cycle, instead of deferring it to system testing. - Implementing an Automated Component Test using Rational QualityArchitect
