Generation of test purposes from Use Case Maps

The Use Case Map (UCM) scenario notation can be used to model service requirements and high-level designs for reactive and distributed systems. It is therefore a natural candidate for use in the process of generating requirements-directed test suites. We survey several approaches for deriving test purposes from UCM models. We distinguish three main approaches. The first approach is based on testing patterns, the second one on UCM scenario definitions, and the third one on transformations to formal specifications (such as Lotos). Several techniques will be briefly illustrated and compared in terms of quality of the test purposes obtained, ease of use, and tool support. We also identify challenges in refining these test purposes into test cases as well as opportunities for improving current UCM-based testing.
