Testing based on sequence diagrams

Base on sequence diagrams,this paper proposed an approach for object-oriented testing at class and cluster-levels.According to sequence diagrams,this approach can pick up class interaction information,generate testing case.And this approach can insert some probe function into source code to generate a testing instruction.Finally,it run the testing instruction by test driver and generates test result.This approach includes solution for sequence diagrams' new characters presented in UML2.0.
