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

// 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)
