Lesson 2: Modelling Languages, Abstraction, and Model Design

This lesson develops practical understanding of modelling languages, abstraction, and model design within the ISTQB Certified Tester Model-Based Testing (CT-MBT) Training. It connects core concepts with realistic testing and quality-engineering decisions.

Learners examine methods, evidence, risks, stakeholder expectations, and implementation considerations before applying the ideas in a focused activity.

Topics Covered

• Behavioral, structural, process, decision, state, and data models
• States, transitions, guards, events, actions, and hierarchies
• Activities, workflows, decisions, causes, effects, and usage
• Abstraction, scope, boundaries, detail, assumptions, and purpose
• Valid, invalid, alternative, exception, concurrent, and timed behavior
• Model correctness, consistency, completeness, readability, and testability
• Traceability among requirements, models, tests, and results

Practical Activity

Apply the lesson concepts to a realistic ISTQB Certified Tester Model-Based Testing (CT-MBT) scenario and document the test approach, evidence, risks, and recommended next actions.

Lesson Outcome

Learners can explain and apply modelling languages, abstraction, and model design using structured, risk-aware, and evidence-based testing decisions.
