📝 Test Case Design Techniques
1. 🎯 Learning Objectives
- Apply equivalence partitioning to reduce test cases
- Design boundary tests for numerical inputs
- Create decision tables for complex logic
- Model system behavior with state transition testing
2. 📖 Core Content
3.1 Equivalence Partitioning
Divide input domain into equivalence classes where all values produce same behavior. Example: Age input field (0-120). Classes: invalid-low (<0), valid (0-120), invalid-high (>120).
3.2 Boundary Value Analysis
Test boundaries of equivalence classes. Most defects occur at boundaries. Example: For range [1, 100], test: 0, 1, 2 (lower) and 99, 100, 101 (upper).
3.3 Decision Tables
For complex business logic with multiple conditions:
| Condition | R1 | R2 | R3 | R4 |
|---|---|---|---|---|
| Age > 18 | T | T | F | F |
| Member | T | F | T | F |
| Discount | 20% | 10% | 5% | 0% |
3.4 State Transition Testing
Model system as states and transitions. Test: valid transitions, invalid transitions, all states reachable.
