Abstract: A method is provided for deriving software tests from use cases. Thereby an activity digram is used to represent the possible use case scenarios. The test case scenarios are derived by applying coverage metrics on the activity diagram. The activities of the diagram are matched with an appertaining test. A test idea document is produced from the test case scenario. System test scenarios are created by concatenating the test case scenarios to a walk-through of the system. The system test cases are further enriched with activities to ensure the test precondition and to verify the test case scenario result. A test design document is produced for the system test.
