Technical Approach

TDD London/Chicago Schools

• London (Mock-based): Component isolation for unit behavior
• Chicago (Integration): Real collaboration for system validation

Test Structure

describe('Learning System Integration Tests', () => {
  beforeEach(() => {
    // Initialize fresh instances
    memoryManager = new SwarmMemoryManager();
    performanceTracker = new PerformanceTracker();
    learningEngine = new LearningEngine();
    improvementLoop = new ImprovementLoop();
  });

  it('should complete full learning flow', async () => {
    // 1. Record baseline
    // 2. Execute & learn
    // 3. Record improved
    // 4. Verify improvement
  });
});

Next Steps

To Execute Tests

1. Fix Logger mock (if needed)

   // tests/__mocks__/src/utils/Logger.ts
   export const Logger = {
     getInstance: () => ({
       info: jest.fn(),
       warn: jest.fn(),
       error: jest.fn(),
       debug: jest.fn()
     })
   };
   

2. Run integration tests

   npm test tests/integration/learning-system.test.ts
   

3. Run performance benchmarks

   npm test tests/performance/learning-overhead.test.ts
