Presentation Transcript

  1. UCM -> SUT model

  2. Team • Alexey Veselov • St.Petersburg State Polytechnic University • Alexander Ivanov • St.Petersburg State Polytechnic University • Igor Nikiforov • St.Petersburg State Polytechnic University • Alexey Zakharov • St.Petersburg State Polytechnic University • Mentor: Sir Tony Hoare

  3. Introduction & Motivation

  4. Goals • Easily readable requirements representation bridges the gap in understanding of project details • Verification of requirements’ consistency

  5. Proposed Approach (general scheme) Specifications Developer Project manager Use case map Checking requirements’ consistency Model based on specifications Customer

  6. Use Case Maps (UCM) • Standardized notation for use cases • ITU-T, Recommendation Z.151 (11/08): User Requirements Notation (URN) - Language Definition (Draft version) • ITU-T, Recommendation Z.150 (02/03): User Requirements Notation (URN) - Language Requirements and Framework

  7. Related Work • Early Availability Requirements Modeling Using UseCase Maps. Hassine, Jameleddine. Information Technology: New Generations (ITNG), 2011 Eighth International Conference on Digital Object Identifier • Use Case Maps as a property specification language.

  8. UCM Primitives (1) StartPoint {s} tr {s’} {s} R {s’} Responsibility Sequential composition {s} R1;R2 {s’’}

  9. UCM Primitives (2) OrFork {s /\ cond1} tr1 {s1} \/ … \/ {s /\ condN} trN {sN} OrFork is alternative (i.e. only one path is selected at a time) {s} stub {s’} Stub stub - encapsulated behavior EndPoint {s} tr {s’}

  10. Concept • Specifications are easily readable; decreasing chance of misunderstanding • Generation of a system’s model (based on UCM representation) • Possible to check specifications’ consistency • Test cases can be easily derived from UCM

  11. Current State and Future Plans • Currently there is a concept only • Next steps: • integration of existent model checking tool • generation of test cases • testing against realistic examples • introduction of concurrency
