Test Structure

Unit Test Template

/**
 * @requirement REQ-XXX-NNN
 * @design DES-XXX-NNN
 */
import { describe, it, expect, beforeEach } from 'vitest';
import { XxxService } from './xxx-service.js';
import { resetXxxCounter } from './xxx-entity.js';

describe('XxxService', () => {
  let service: XxxService;
  let repository: MockXxxRepository;

  beforeEach(() => {
    // BP-TEST-001: Reset counters before each test
    resetXxxCounter();
    repository = new MockXxxRepository();
    service = new XxxService(repository);
  });

  describe('create', () => {
    it('should create entity with valid input', async () => {
      // Arrange
      const input = { name: 'Test', value: 100 };
      
      // Act
      const result = await service.create(input);
      
      // Assert
      expect(result.isOk()).toBe(true);
      if (result.isOk()) {
        expect(result.value.name).toBe('Test');
      }
    });

    it('should return error for invalid input', async () => {
      // Arrange
      const input = { name: '', value: -1 };
      
      // Act
      const result = await service.create(input);
      
      // Assert
      expect(result.isErr()).toBe(true);
    });
  });
});

Integration Test Template

/**
 * @requirement REQ-XXX-NNN
 * @design DES-XXX-NNN
 */
import { describe, it, expect, beforeAll, afterAll } from 'vitest';

describe('XxxService Integration', () => {
  beforeAll(async () => {
    // Setup test environment
  });

  afterAll(async () => {
    // Cleanup
  });

  it('should complete full workflow', async () => {
    // Test full user journey
  });
});
