  2. ALL4TEC Since 1998 French: 45 experts Turnover 2010: 4 M€ Expertise offer: • PROCESS IMPROVEMENT • SAFETY ENGINEERING • SYSTEM ENGINEERING • OPTIMIZED TESTING • SOFTWARE RELIABILITY EMBEDDED SYSTEMS

  3. OUR COMPETENCES OFFER MaTeLo EXAM M Elopée Safety Architect

  4. AGENDA • THE TEST PROBLEM • THE EXPECTED SOLUTION • THE MODEL-BASED TESTING SOLUTION • A PRAGMATIC INDUSTRIAL USE-CASE • A MORE STANDARDIZED TOOLS INTEGRATION

  5. THE TESTING PROBLEM • Test Resources Lack • Test Focus Deviation Testing Effort Test Needs System Complexity Test Availability Time Usage Intensity Reliability Market Expectation Reality Product Life Customer Validation Normal Usage Development Phase

  6. HOW TO SOLVE THIS ISSUE?

  7. MODEL-DRIVEN ENGINEERING Functional Requirements DESIGN TEST Implement Scenarize Design Model Usage Model MaTeLo Generate Generate Model Based Testing Code Test Cases Compile Derive Test Environment Test Scripts EXE

  8. More Productive Coverage WHAT IS MaTeLo? Formal Test Specification Product Usage Point of View MaTeLo Fully Measured Process Markov Test Logic Test Execution Compatibility Bidirectional Requirements Traceability Systematic Engineering Productivity

  11. MaTeLo EDITORUsage Model Design

  12. MATELO USAGE MODELS • Probability on every Alternatives • Association of Requirements • Configuration of Test Operations • Setup Transition as Test Step BEGINNING TRANSITION MACRO CHAIN STATE END

  13. MODEL TRANSITION = TEST STEP Select_Gear(5) Accelerate(100%) Check_Speed(185) Requirements Test Operations Stimulations Inputs Stimulation Equivalence Classes Timing • Test Oracle • Outputs = f(Inputs) • Verifications • Expected Outputs • Timing

  14. MATELO PROFILE • Profiles can be embedded to qualify the usage model • Operational profiles • Test profiles 87 (+/- 25) Data distribution Usage path probability 347 0-100-150-200-500
