## Description

Focus testing effort on highest-risk areas using risk assessment and prioritization. Use when planning test strategy, allocating testing resources, or making coverage decisions.

# Risk-Based Testing

<default_to_action>
When planning tests or allocating testing resources:
1. IDENTIFY risks per component (use 1-5 scale for probability and impact)
2. PRIORITIZE: Critical (20+) → High (12-19) → Medium (6-11) → Low (1-5)
3. ALLOCATE effort: 60% critical, 25% high, 10% medium, 5% low
4. REASSESS continuously: Production incidents raise risk; stable code lowers it
</default_to_action>

## Quick Reference Card

### When to Use
- Planning sprint/release test strategy
- Deciding what to automate first
- Allocating limited testing time
- Justifying test coverage decisions

### Effort Allocation by Risk Score
| Score | Priority | Effort | Action |
|-------|----------|--------|--------|
| 20-25 | Critical | 60% | Comprehensive testing, multiple techniques |
| 12-19 | High | 25% | Thorough testing, automation priority |
| 6-11 | Medium | 10% | Standard testing, basic automation |
| 1-5 | Low | 5% | Smoke test, exploratory only |

## Apply Test Depth by Risk
```typescript
await Task("Risk-Based Test Generation", {
  critical: {
    features: ['checkout', 'payment'],
    depth: 'comprehensive',
    techniques: ['unit', 'integration', 'e2e', 'performance', 'security']
  },
  high: {
    features: ['auth', 'user-profile'],
    depth: 'thorough',
    techniques: ['unit', 'integration', 'e2e']
  },
  medium: {
    features: ['search', 'notifications'],
    depth: 'standard',
    techniques: ['unit', 'integration']
  },
  low: {
    features: ['admin-panel', 'settings'],
    depth: 'smoke',
    techniques: ['smoke-tests']
  }
}, "qe-test-generator");
```

### Step 3: Reassess Dynamically
```typescript
// Production incident increases risk
await Task("Update Risk Score", {
  feature: 'search',
  event: 'production-incident',
  previousRisk: 9,
  newProbability: 5,  // Increased due to incident
  newRisk: 15         // Now HIGH priority
}, "qe-regression-risk-analyzer");
```
