Reuse of Integration Test Cases in the Software Product Line Development A model-based Technique for the automated Test Case Derivation

The development process in software product line engineering is divided into domain engineering and application engineering. The reuse of test artefacts from domain engineering can significantly reduce the test effort in application engineering. Existing approaches in testing software product lines focus on unit and system testing. In this paper an integrated and model-based technique for the automated generation of logical integration test cases for software product lines is presented. The technique includes the generation of reusable integration test cases in domain engineering as well as the derivation of application test cases by reusing the domain test cases. The reusable integration test cases additionally support an early test of the product line plattform in domain engineering. With quantitative measurements the applicability and the potential benefit of the technique have been evaluated.
