Test Design Techniques

<default_to_action> When designing test cases systematically:

1. APPLY Boundary Value Analysis (test at min, max, edges)
2. USE Equivalence Partitioning (one test per partition)
3. CREATE Decision Tables (for complex business rules)
4. MODEL State Transitions (for stateful behavior)
5. REDUCE with Pairwise Testing (for combinations)

Quick Design Selection:

• Numeric ranges → BVA + EP
• Multiple conditions → Decision Tables
• Workflows → State Transition
• Many parameters → Pairwise Testing

Critical Success Factors:

• Systematic design finds more bugs with fewer tests
• Random testing is inefficient
