## Description

Apply Edward de Bono's Six Thinking Hats methodology to software testing for comprehensive quality analysis. Use when designing test strategies, conducting test retrospectives, analyzing test failures, evaluating testing approaches, or facilitating testing discussions. Each hat provides a distinct testing perspective: facts (White), risks (Black), benefits (Yellow), creativity (Green), emotions (Red), and process (Blue).

# Six Thinking Hats for Testing

<default_to_action>
When analyzing testing decisions:
1. DEFINE focus clearly (specific testing question)
2. APPLY each hat sequentially (5 min each)
3. DOCUMENT insights per hat
4. SYNTHESIZE into action plan

**Quick Hat Rotation (30 min):**
```markdown
🤍 WHITE (5 min) - Facts only: metrics, data, coverage
❤️ RED (3 min) - Gut feelings (no justification needed)
🖤 BLACK (7 min) - Risks, gaps, what could go wrong
💛 YELLOW (5 min) - Strengths, opportunities, what works
💚 GREEN (7 min) - Creative ideas, alternatives
🔵 BLUE (3 min) - Action plan, next steps
```

**Example for "API Test Strategy":**
- 🤍 47 endpoints, 30% coverage, 12 integration tests
- ❤️ Anxious about security, confident on happy paths
- 🖤 No auth tests, rate limiting untested, edge cases missing
- 💛 Good docs, CI/CD integrated, team experienced
- 💚 Contract testing with Pact, chaos testing, property-based
- 🔵 Security tests first, contract testing next sprint

## Quick Reference Card

### The Six Hats

| Hat | Focus | Key Question |
|-----|-------|--------------|
| 🤍 **White** | Facts & Data | What do we KNOW? |
| ❤️ **Red** | Emotions | What do we FEEL? |
| 🖤 **Black** | Risks | What could go WRONG? |
| 💛 **Yellow** | Benefits | What's GOOD? |
| 💚 **Green** | Creativity | What ELSE could we try? |
| 🔵 **Blue** | Process | What should we DO? |

### When to Use Each Hat

| Hat | Use For |
|-----|---------|
| 🤍 White | Baseline metrics, test data inventory |
| ❤️ Red | Team confidence check, quality gut feel |
| 🖤 Black | Risk assessment, gap analysis, pre-mortems |
| 💛 Yellow | Strengths audit, quick win identification |
| 💚 Green | Test innovation, new approaches, brainstorming |
| 🔵 Blue | Strategy planning, retrospectives, decision-making |
