Problem

Keine Tests im gesamten Projekt!

  • Keine Regressionserkennung
  • Refactoring ist riskant
  • Bugs werden erst in Produktion entdeckt
  • Keine Dokumentation des erwarteten Verhaltens

Lösung

Test-Strategie

Typ Fokus Tools
Unit Tests Einzelne Funktionen/Klassen Vitest
Integration Tests Service-Interaktionen Vitest + SQLite in-memory
E2E Tests Vollständige Workflows Playwright (optional)

1. Test-Setup

// vitest.config.ts (Root)
import { defineConfig } from 'vitest/config';

export default defineConfig({
  test: {
    globals: true,
    environment: 'node',
    coverage: {
      provider: 'v8',
      reporter: ['text', 'html'],
      exclude: ['**/node_modules/**', '**/dist/**'],
    },
  },
});
// package.json
{
  "scripts": {
    "test": "vitest",
    "test:coverage": "vitest --coverage",
    "test:watch": "vitest --watch"
  }
}

2. Database Tests

// packages/database/src/__tests__/repositories/observation.test.ts
import { describe, it, expect, beforeEach, afterEach } from 'vitest';
import { MikroORM } from '@mikro-orm/sqlite';
import { ObservationRepository } from '../../repositories/ObservationRepository';

describe('ObservationRepository', () => {
  let orm: MikroORM;
  let repo: ObservationRepository;
  
  beforeEach(async () => {
    orm = await MikroORM.init({
      dbName: ':memory:',
      entities: [Observation, Session],
      // ... config
    });
    await orm.getSchemaGenerator().createSchema();
    repo = new ObservationRepository(orm.em);
  });
  
  afterEach(async () => {
    await orm.close();
  });
  
  describe('create', () => {
    it('should create observation with all fields', async () => {
      const obs = await repo.create({
        memorySessionId: 'session-1',
        project: 'test-project',
        type: 'discovery',
        title: 'Test Discovery',
        text: 'Some text',
      });
      
      expect(obs.id).toBeDefined();
      expect(obs.title).toBe('Test Discovery');
      expect(obs.createdAtEpoch).toBeGreaterThan(0);
    });
    
    it('should reject invalid type', async () => {
      await expect(repo.create({
        memorySessionId: 'session-1',
        project: 'test-project',
        type: 'invalid-type' as any,
        title: 'Test',
      })).rejects.toThrow();
    });
  });
  
  describe('search', () => {
    it('should find observations by FTS query', async () => {
      await repo.create({ /* ... */ title: 'Authentication flow' });
      await repo.create({ /* ... */ title: 'Database setup' });
      
      const results = await repo.search('authentication');
      
      expect(results).toHaveLength(1);
      expect(results[0].title).toContain('Authentication');
    });
  });
  
  describe('batchDelete', () => {
    it('should delete multiple observations', async () => {
      const obs1 = await repo.create({ /* ... */ });
      const obs2 = await repo.create({ /* ... */ });
      const obs3 = await repo.create({ /* ... */ });
      
      const deleted = await repo.batchDelete([obs1.id, obs2.id]);
      
      expect(deleted).toBe(2);
      expect(await repo.findById(obs3.id)).toBeDefined();
    });
  });
});

3. Backend Service Tests

// packages/backend/src/__tests__/services/task-service.test.ts
import { describe, it, expect, vi, beforeEach } from 'vitest';
import { TaskService } from '../../services/TaskService';

describe('TaskService', () => {
  let service: TaskService;
  let mockTaskRepo: any;
  let mockWorkerHub: any;
  
  beforeEach(() => {
    mockTaskRepo = {
      create: vi.fn(),
      findById: vi.fn(),
      update: vi.fn(),
    };
    mockWorkerHub = {
      getAvailableWorker: vi.fn(),
      assignTask: vi.fn(),
    };
    service = new TaskService(mockTaskRepo, mockWorkerHub);
  });
  
  describe('queueTask', () => {
    it('should create task with correct defaults', async () => {
      mockTaskRepo.create.mockResolvedValue({ id: 'task-1' });
      
      await service.queueTask({
        type: 'observation',
        payload: { sessionId: 'session-1' },
      });
      
      expect(mockTaskRepo.create).toHaveBeenCalledWith(expect.objectContaining({
        type: 'observation',
        status: 'pending',
        priority: 0,
      }));
    });
    
    it('should reject when queue is full', async () => {
      mockTaskRepo.countByStatus.mockResolvedValue({ pending: 1001 });
      
      await expect(service.queueTask({ /* ... */ }))
        .rejects.toThrow('Task queue full');
    });
  });
  
  describe('dispatchTasks', () => {
    it('should assign task to available worker', async () => {
      mockTaskRepo.findPending.mockResolvedValue([{ id: 'task-1', type: 'observation' }]);
      mockWorkerHub.getAvailableWorker.mockReturnValue({ id: 'worker-1' });
      
      await service.dispatchTasks();
      
      expect(mockWorkerHub.assignTask).toHaveBeenCalledWith('worker-1', 'task-1');
    });
  });
});

4. API Route Tests

// packages/backend/src/__tests__/routes/data.test.ts
import { describe, it, expect, beforeAll, afterAll } from 'vitest';
import request from 'supertest';
import { createApp } from '../../app';

describe('Data Routes', () => {
  let app: Express;
  
  beforeAll(async () => {
    app = await createApp({ dbName: ':memory:' });
  });
  
  describe('GET /api/data/projects', () => {
    it('should return list of projects', async () => {
      const res = await request(app)
        .get('/api/data/projects')
        .expect(200);
      
      expect(res.body).toBeInstanceOf(Array);
    });
  });
  
  describe('POST /api/data/observations', () => {
    it('should create observation', async () => {
      const res = await request(app)
        .post('/api/data/observations')
        .send({
          memorySessionId: 'session-1',
          project: 'test',
          type: 'discovery',
          title: 'Test',
        })
        .expect(201);
      
      expect(res.body.id).toBeDefined();
    });
    
    it('should validate required fields', async () => {
      await request(app)
        .post('/api/data/observations')
        .send({ title: 'Missing fields' })
        .expect(400);
    });
  });
});

5. Worker Handler Tests

// packages/worker/src/__tests__/handlers/observation.test.ts
import { describe, it, expect, vi } from 'vitest';
import { ObservationHandler } from '../../handlers/observation';

describe('ObservationHandler', () => {
  describe('generateObservation', () => {
    it('should generate observation from tool data', async () => {
      const mockAgent = {
        generateObservation: vi.fn().mockResolvedValue({
          title: 'Generated Title',
          type: 'discovery',
        }),
      };
      
      const handler = new ObservationHandler(mockAgent);
      const result = await handler.handle({
        toolName: 'Read',
        toolInput: { path: '/some/file.ts' },
        toolOutput: 'file contents...',
      });
      
      expect(result.title).toBe('Generated Title');
    });
    
    it('should truncate long inputs', async () => {
      const longInput = 'x'.repeat(10000);
      // ...
    });
  });
});

Test Suite Implemented

Summary

Implemented comprehensive test coverage for the project:

Backend Tests:

  • task-service.test.ts - 26 tests covering task queueing, backpressure, capability resolution
  • data-router.test.ts - 34 tests covering sessions, observations, documents, templates, project settings
  • search-router.test.ts - 30 tests covering text search, semantic search, timeline, combined search

Worker Tests:

  • observation-handler.test.ts - 20 tests for observation extraction with mocked AI agent
  • summarize-handler.test.ts - 19 tests for session summarization with mocked AI agent

CI/CD Updates

  • CI now runs pnpm run test:coverage instead of pnpm run test
  • Coverage reports uploaded as artifacts (7-day retention)
  • Initial coverage thresholds set to 15% (baseline to be increased over time)

Metrics

  • Total: 416 tests across 18 test files
  • All tests passing
  • Coverage configured with v8 provider and HTML/JSON reporters

Dependencies Added

  • supertest and @types/supertest for HTTP route testing
