An Evaluation of Assuring Test Case Sufficiency Using a D-Case Pattern

To assure the sufficiency of testing, it is necessary to build consensus among stakeholders such as system acquirers, developers, and test engineers who validate that implementation of the system satisfies requirements. In this paper, a safety case pattern is proposed to assure the sufficiency of testing based on requirements descriptions and deviation analysis. The proposed method is also evaluated by applying it to the creation of an integration test case creation for a financial application package requirements.
