Discussion Topics:

• What is state transition testing, and how does it model system behavior?
• How do you create a state transition diagram for a software system?
• Discuss the challenges of testing state-based systems in real-world applications.
• How does state transition testing complement other black box testing techniques?

Lesson Summary: Students learn state transition-based testing, focusing on modeling system states and transitions using diagrams. Practical exercises involve drawing tools to create state transition diagrams. Assessments include viva and lab final, aligning with CLO1 (understanding testing techniques).

Instructions for Lab Report 5:

Lab Report 5: State Transition Testing for Dynamic Systems

Objective: Apply State Transition Testing to validate state-based system behavior.

Learning Outcome: Students will be able to draw state transition diagrams and design test cases to verify state changes, demonstrating understanding of dynamic system testing (CLO1, PLO1, Cognitive Domain: Apply - C3).

Tools Required: Any drawing tool (e.g., Draw.io, Lucidchart) and a C Compiler.

Instructions:

1. Select a program with state-based behavior (e.g., a vending machine simulation).
2. Draw a state transition diagram representing all states and transitions.
3. Design test cases to cover all valid and invalid state transitions.
4. Implement the test cases in a C compiler and execute them.
5. Analyze the system’s behavior for correct state transitions.

Deliverables:

• A lab report with the state transition diagram, test cases, execution results, and analysis.
• Include the diagram as an image.

Assessment: Viva, Lab Final (CLO1, PLO1).
