# Test Design Techniques <default_to_action> When designing test cases, select technique by input type: - Numeric ranges → BVA + EP - Multiple conditions → Decision Tables - Workflows → State Transition - Many parameter combinations → Pairwise Testing </default_to_action> ## Quick Reference Card ### When to Use - Designing new test suites - Optimizing existing tests - Complex business rules - Reducing test redundancy --- ## Agent-Driven Test Design ```typescript // Auto-generate BVA tests await Task("Generate BVA Tests", { field: 'age', dataType: 'integer', constraints: { min: 18, max: 120 } }, "qe-test-generator"); // Returns: 6 boundary test cases // Auto-generate pairwise tests await Task("Generate Pairwise Tests", { parameters: { browser: ['Chrome', 'Firefox', 'Safari'], os: ['Windows', 'Mac', 'Linux'], screen: ['Desktop', 'Tablet', 'Mobile'] } }, "qe-test-generator"); // Returns: 9-12 tests (vs 27 full combination) ``` --- ## Agent Coordination Hints ### Memory Namespace ``` aqe/test-design/ ├── bva-analysis/* - Boundary value tests ├── partitions/* - Equivalence partitions ├── decision-tables/* - Decision table tests └── pairwise/* - Combinatorial reduction ``` ### Fleet Coordination ```typescript const designFleet = await FleetManager.coordinate({ strategy: 'systematic-test-design', agents: [ 'qe-test-generator', // Apply design techniques 'qe-coverage-analyzer', // Analyze coverage 'qe-quality-analyzer' // Assess test quality ], topology: 'sequential' }); ``` --- ## Related Skills - [agentic-quality-engineering](../agentic-quality-engineering/) - Agent-driven testing - [risk-based-testing](../risk-based-testing/) - Prioritize by risk - [mutation-testing](../mutation-testing/) - Validate test effectiveness --- ## Remember **With Agents:** `qe-test-generator` applies these techniques automatically, generating optimal test suites with maximum coverage and minimum redundancy. Agents identify boundaries, partitions, and combinations from code analysis.
