🧠 Test Intelligence System

The most advanced, AI-powered testing framework you've ever seen.

This is not your typical test suite. This is a next-generation, self-aware testing ecosystem that combines cutting-edge AI, chaos engineering, mutation testing, performance profiling, and self-healing capabilities into a single, unified platform.

🚀 What Makes This Mind-Blowing?

1. AI-Powered Auto-Test Generation 🤖

The system analyzes your codebase using AST (Abstract Syntax Tree) parsing and automatically generates comprehensive tests for every API endpoint.

pnpm test:auto-generate

Features:

• ✅ Analyzes TypeScript code structure
• ✅ Extracts validation schemas, permissions, and error cases
• ✅ Generates happy path, authentication, authorization, and edge case tests
• ✅ Creates 5-10 tests per endpoint automatically
• ✅ Saves hours of manual test writing

Example Output:

Analyzing apps/web/app/api/schedules/route.ts...
✅ Generated tests/api/schedules/__tests__/auto-generated.test.ts
   ✓ Happy path
   ✓ Authentication required
   ✓ Permission check: admin, manager
   ✓ Input validation
   ✓ Type validation
   ✓ Concurrent request handling

Total: 33 endpoints × 6 tests = 198 auto-generated tests!

2. Performance Profiling & Regression Detection 📊

Every API request is profiled in real-time with:

• Response time (P50, P95, P99)
• Memory usage
• CPU time
• Throughput

The system detects performance regressions by comparing against baselines and generates actionable recommendations.

pnpm test:performance

Features:

• ✅ Automatic baseline creation
• ✅ Regression detection (>20% degradation = alert)
• ✅ Beautiful HTML reports with Chart.js visualizations
• ✅ Performance heatmaps
• ✅ Optimization recommendations

Example Report:

⚠️  POST /api/schedules has slow P95 latency (1,234ms). Consider:
   - Adding database indexes
   - Implementing caching
   - Optimizing database queries

3. Contract Testing with Auto-Generated OpenAPI Specs 📋

Tests are converted into living API documentation. The system:

• Validates request/response contracts
• Generates OpenAPI 3.0 specifications
• Creates interactive Swagger UI documentation
• Detects contract violations

pnpm test:contracts

Features:

• ✅ Automatic OpenAPI spec generation from Zod schemas
• ✅ Request/response validation
• ✅ Swagger UI with interactive API explorer
• ✅ Contract violation reports
• ✅ API versioning support

Generated Files:

• docs/openapi.json - Full OpenAPI 3.0 spec
• docs/api-docs.html - Interactive Swagger UI

4. Mutation Testing 🧬

Validates the quality of your tests by introducing bugs into your code and ensuring tests catch them.

pnpm test:mutation

Mutation Operators:

• Conditional Boundary: < → <=, > → >=
• Arithmetic: + → -, * → /
• Logical: && → ||
• Negation: Add/remove !
• Return Values: true → false, 0 → 1
• Comparisons: == → !=

Example Report:

🧬  MUTATION TESTING REPORT
══════════════════════════════════════════════════════════════════════

📊 Summary:
   Total Mutants: 156
   Killed: 142 ✅
   Survived: 14 ❌
   Mutation Score: 91.0%

🏆 Excellent! Your tests are high quality.

❌ Survived Mutants (Test Weaknesses):
   mutant-42 - ConditionalBoundary
   File: apps/web/app/api/schedules/route.ts:78
   Original: <
   Mutated:  <=
   💡 Add a test case to catch this mutation!

5. Self-Healing Test Framework 🔧

Tests that automatically fix themselves when code changes.

Features:

• ✅ Analyzes test failures
• ✅ Suggests healing actions with confidence scores
• ✅ Automatically applies high-confidence fixes
• ✅ Detects flaky tests
• ✅ Updates selectors, assertions, and data
• ✅ Adds retry logic for intermittent failures

Healing Actions:

1. Selector Updates - Element locators changed
2. Assertion Updates - Expected values changed due to code updates
3. Timeout Increases - Slow-loading elements
4. Retry Addition - Flaky test detection
5. Data Updates - Unique constraint violations

Example:

🔧 Auto-healed test: "should create organization"
  ✓ Updated assertion (confidence: 85%)
    Old: expect(name).toBe('Test Org')
    New: expect(name).toBe('Test Organization')
  ✓ Made test data dynamic (confidence: 90%)
    Old: subdomain: 'test-org'
    New: subdomain: `test-org-${Date.now()}`

6. Chaos Engineering 🌪️

Intentionally breaks your system to test resilience and error handling.

pnpm test:chaos

Chaos Experiments:

1. High Latency - 5s delays (30% probability)
2. Random 500 Errors - Internal server errors (10% probability)
3. Database Failures - Connection errors (5% probability)
4. Network Timeouts - Simulated network issues (5% probability)
5. Rate Limiting - 429 responses (15% probability)
6. Intermittent Failures - Random 503 errors (20% probability)

Example Report:

🌪️  CHAOS ENGINEERING REPORT
══════════════════════════════════════════════════════════════════════

Experiment: High Latency
Type: latency
Probability: 30%
Status: 🟢 Active

Results:
  Total Requests: 100
  Affected Requests: 32
  System Behavior: GRACEFUL

✅ System handled chaos gracefully

Recommendations:
  ✅ System handled chaos gracefully
  💡 Add database connection pooling and retry logic
  💡 Implement request timeouts and circuit breakers

7. Test Analytics Dashboard 📈

Real-time insights with interactive visualizations.

pnpm test:analytics

Features:

• ✅ Pass rate trends (last 10 runs)
• ✅ Performance trends
• ✅ Slowest tests identification
• ✅ Flaky test detection
• ✅ Coverage heatmaps
• ✅ Actionable recommendations
• ✅ Beautiful HTML dashboard with Chart.js

Dashboard Metrics:

• Total Tests
• Pass Rate
• Average Duration
• Flaky Tests Count
• Coverage by File
• Trends Over Time

View Dashboard:

open tests/intelligence/dashboard.html

8. CI/CD Integration with Deployment Validation 🚀

Production-grade deployment strategies with automated validation and rollback.

Deployment Strategies:

1. Blue-Green - Zero-downtime deployment
2. Canary - Gradual rollout with monitoring
3. Rolling - Instance-by-instance updates

Features:

• ✅ Pre-deployment validation tests
• ✅ Canary analysis (error rate, latency, throughput)
• ✅ Automated rollback on failure
• ✅ Post-deployment smoke tests
• ✅ GitHub Actions workflow generation

Example:

const result = await cicd.validateDeployment({
  environment: "production",
  strategy: "canary",
  validationTests: ["tests/e2e/critical"],
  canaryPercentage: 10,
  rollbackOnFailure: true,
});

// Deploys to 10% traffic
// Monitors error rate, latency
// Auto-promotes if healthy OR auto-rollback if issues detected
