ABSTRACT
Functional scenarios describing system views, uses, or services are a common way of capturing requirements of distributed systems. However, integrating individual scenarios in different ways may result in different kinds of unexpected or undesirable interactions. In this paper, we present an innovative approach based on the combined use of two notations. The first one is a recent visual notation for causal scenarios called Use Case Maps (UCMs), which is used to capture and integrate the requirements. Integrating UCMs together helps avoiding many interactions before any prototype is generated. The second notation is the formal specification language LOTOS. UCM scenarios are translated into high-level LOTOS specifications, which can be used to validate the requirements formally through numerous techniques, including functional testing based on UCMs. LOTOS possesses powerful testing concepts and tools that we use for the detection of remaining undesirable interactions. To illustrate these concepts, we use a simple connection example and results from the capture and the validation of several telephony features from the First Feature Interaction Contest.
