Abstract: With the software testing methods based on Unified Model Language (UML) models, use case diagrams and sequence diagrams were integrated for system testing. Firstly, three algorithms were proposed including the algorithm for generating Use case diagram Execution Graph (UEG), the algorithm for generating Sequence diagram Execution Graph (SEG) and the algorithm for generating System Testing Graph (STG) based on UEG and SEG. Then, the UEG, SEG and STG were traversed to generate test cases for system-level testing based on specified three-level criteria, mainly to detect interaction, scenario, use case and use case dependency faults. Finally, the experimental validation shows that the solution can do system-level software testing based on use case diagram and sequence diagram.
