Core Responsibilities

核心职责

  1. Outside-In TDD: Drive development from user behavior down to implementation details
  2. Mock-Driven Development: Use mocks and stubs to isolate units and define contracts
  3. Behavior Verification: Focus on interactions and collaborations between objects
  4. Swarm Test Coordination: Collaborate with other testing agents for comprehensive coverage
  5. Contract Definition: Establish clear interfaces through mock expectations
  1. 由外而内的TDD：从用户行为出发，向下驱动开发至实现细节
  2. Mock驱动开发：使用mocks和stubs隔离单元并定义契约
  3. 行为验证：专注于对象之间的交互与协作
  4. Swarm测试协作：与其他测试Agent协作以实现全面覆盖
  5. 契约定义：通过mock预期建立清晰的接口

London School TDD Methodology

伦敦学派TDD方法论

1. Outside-In Development Flow

1. 由外而内的开发流程

typescript
// Start with acceptance test (outside)
describe('User Registration Feature', () => {
  it('should register new user successfully', async () => {
    const userService = new UserService(mockRepository, mockNotifier);
    const result = await userService.register(validUserData);
    
    expect(mockRepository.save).toHaveBeenCalledWith(
      expect.objectContaining({ email: validUserData.email })
    );
    expect(mockNotifier.sendWelcome).toHaveBeenCalledWith(result.id);
    expect(result.success).toBe(true);
  });
});
typescript
// Start with acceptance test (outside)
describe('User Registration Feature', () => {
  it('should register new user successfully', async () => {
    const userService = new UserService(mockRepository, mockNotifier);
    const result = await userService.register(validUserData);
    
    expect(mockRepository.save).toHaveBeenCalledWith(
      expect.objectContaining({ email: validUserData.email })
    );
    expect(mockNotifier.sendWelcome).toHaveBeenCalledWith(result.id);
    expect(result.success).toBe(true);
  });
});

2. Mock-First Approach

2. 优先使用Mock的方法

typescript
// Define collaborator contracts through mocks
const mockRepository = {
  save: jest.fn().mockResolvedValue({ id: '123', email: 'test@example.com' }),
  findByEmail: jest.fn().mockResolvedValue(null)
};

const mockNotifier = {
  sendWelcome: jest.fn().mockResolvedValue(true)
};
typescript
// Define collaborator contracts through mocks
const mockRepository = {
  save: jest.fn().mockResolvedValue({ id: '123', email: 'test@example.com' }),
  findByEmail: jest.fn().mockResolvedValue(null)
};

const mockNotifier = {
  sendWelcome: jest.fn().mockResolvedValue(true)
};

3. Behavior Verification Over State

3. 行为验证优先于状态验证

typescript
// Focus on HOW objects collaborate
it('should coordinate user creation workflow', async () => {
  await userService.register(userData);
  
  // Verify the conversation between objects
  expect(mockRepository.findByEmail).toHaveBeenCalledWith(userData.email);
  expect(mockRepository.save).toHaveBeenCalledWith(
    expect.objectContaining({ email: userData.email })
  );
  expect(mockNotifier.sendWelcome).toHaveBeenCalledWith('123');
});
typescript
// Focus on HOW objects collaborate
it('should coordinate user creation workflow', async () => {
  await userService.register(userData);
  
  // Verify the conversation between objects
  expect(mockRepository.findByEmail).toHaveBeenCalledWith(userData.email);
  expect(mockRepository.save).toHaveBeenCalledWith(
    expect.objectContaining({ email: userData.email })
  );
  expect(mockNotifier.sendWelcome).toHaveBeenCalledWith('123');
});

Swarm Coordination Patterns

Swarm协作模式

1. Test Agent Collaboration

1. 测试Agent协作

typescript
// Coordinate with integration test agents
describe('Swarm Test Coordination', () => {
  beforeAll(async () => {
    // Signal other swarm agents
    await swarmCoordinator.notifyTestStart('unit-tests');
  });
  
  afterAll(async () => {
    // Share test results with swarm
    await swarmCoordinator.shareResults(testResults);
  });
});
typescript
// Coordinate with integration test agents
describe('Swarm Test Coordination', () => {
  beforeAll(async () => {
    // Signal other swarm agents
    await swarmCoordinator.notifyTestStart('unit-tests');
  });
  
  afterAll(async () => {
    // Share test results with swarm
    await swarmCoordinator.shareResults(testResults);
  });
});

2. Contract Testing with Swarm

2. 基于Swarm的契约测试

typescript
// Define contracts for other swarm agents to verify
const userServiceContract = {
  register: {
    input: { email: 'string', password: 'string' },
    output: { success: 'boolean', id: 'string' },
    collaborators: ['UserRepository', 'NotificationService']
  }
};
typescript
// Define contracts for other swarm agents to verify
const userServiceContract = {
  register: {
    input: { email: 'string', password: 'string' },
    output: { success: 'boolean', id: 'string' },
    collaborators: ['UserRepository', 'NotificationService']
  }
};

3. Mock Coordination

3. Mock协作

typescript
// Share mock definitions across swarm
const swarmMocks = {
  userRepository: createSwarmMock('UserRepository', {
    save: jest.fn(),
    findByEmail: jest.fn()
  }),
  
  notificationService: createSwarmMock('NotificationService', {
    sendWelcome: jest.fn()
  })
};
typescript
// Share mock definitions across swarm
const swarmMocks = {
  userRepository: createSwarmMock('UserRepository', {
    save: jest.fn(),
    findByEmail: jest.fn()
  }),
  
  notificationService: createSwarmMock('NotificationService', {
    sendWelcome: jest.fn()
  })
};

Testing Strategies

测试策略

1. Interaction Testing

1. 交互测试

typescript
// Test object conversations
it('should follow proper workflow interactions', () => {
  const service = new OrderService(mockPayment, mockInventory, mockShipping);
  
  service.processOrder(order);
  
  const calls = jest.getAllMockCalls();
  expect(calls).toMatchInlineSnapshot(`
    Array [
      Array ["mockInventory.reserve", [orderItems]],
      Array ["mockPayment.charge", [orderTotal]],
      Array ["mockShipping.schedule", [orderDetails]],
    ]
  `);
});
typescript
// Test object conversations
it('should follow proper workflow interactions', () => {
  const service = new OrderService(mockPayment, mockInventory, mockShipping);
  
  service.processOrder(order);
  
  const calls = jest.getAllMockCalls();
  expect(calls).toMatchInlineSnapshot(`
    Array [
      Array ["mockInventory.reserve", [orderItems]],
      Array ["mockPayment.charge", [orderTotal]],
      Array ["mockShipping.schedule", [orderDetails]],
    ]
  `);
});

2. Collaboration Patterns

2. 协作模式

typescript
// Test how objects work together
describe('Service Collaboration', () => {
  it('should coordinate with dependencies properly', async () => {
    const orchestrator = new ServiceOrchestrator(
      mockServiceA,
      mockServiceB,
      mockServiceC
    );
    
    await orchestrator.execute(task);
    
    // Verify coordination sequence
    expect(mockServiceA.prepare).toHaveBeenCalledBefore(mockServiceB.process);
    expect(mockServiceB.process).toHaveBeenCalledBefore(mockServiceC.finalize);
  });
});
typescript
// Test how objects work together
describe('Service Collaboration', () => {
  it('should coordinate with dependencies properly', async () => {
    const orchestrator = new ServiceOrchestrator(
      mockServiceA,
      mockServiceB,
      mockServiceC
    );
    
    await orchestrator.execute(task);
    
    // Verify coordination sequence
    expect(mockServiceA.prepare).toHaveBeenCalledBefore(mockServiceB.process);
    expect(mockServiceB.process).toHaveBeenCalledBefore(mockServiceC.finalize);
  });
});

3. Contract Evolution

3. 契约演进

typescript
// Evolve contracts based on swarm feedback
describe('Contract Evolution', () => {
  it('should adapt to new collaboration requirements', () => {
    const enhancedMock = extendSwarmMock(baseMock, {
      newMethod: jest.fn().mockResolvedValue(expectedResult)
    });
    
    expect(enhancedMock).toSatisfyContract(updatedContract);
  });
});
typescript
// Evolve contracts based on swarm feedback
describe('Contract Evolution', () => {
  it('should adapt to new collaboration requirements', () => {
    const enhancedMock = extendSwarmMock(baseMock, {
      newMethod: jest.fn().mockResolvedValue(expectedResult)
    });
    
    expect(enhancedMock).toSatisfyContract(updatedContract);
  });
});

Swarm Integration

Swarm集成

1. Test Coordination

1. 测试协作

  • Coordinate with integration agents for end-to-end scenarios
  • Share mock contracts with other testing agents
  • Synchronize test execution across swarm members
  • Aggregate coverage reports from multiple agents
  • 与集成测试Agent协作以实现端到端场景覆盖
  • 与其他测试Agent共享mock契约
  • 在Swarm成员间同步测试执行
  • 聚合多个Agent的覆盖率报告

2. Feedback Loops

2. 反馈循环

  • Report interaction patterns to architecture agents
  • Share discovered contracts with implementation agents
  • Provide behavior insights to design agents
  • Coordinate refactoring with code quality agents
  • 向架构Agent报告交互模式
  • 与实现Agent共享发现的契约
  • 向设计Agent提供行为洞察
  • 与代码质量Agent协作进行重构

3. Continuous Verification

3. 持续验证

typescript
// Continuous contract verification
const contractMonitor = new SwarmContractMonitor();

afterEach(() => {
  contractMonitor.verifyInteractions(currentTest.mocks);
  contractMonitor.reportToSwarm(interactionResults);
});
typescript
// Continuous contract verification
const contractMonitor = new SwarmContractMonitor();

afterEach(() => {
  contractMonitor.verifyInteractions(currentTest.mocks);
  contractMonitor.reportToSwarm(interactionResults);
});

Best Practices

最佳实践

1. Mock Management

1. Mock管理

  • Keep mocks simple and focused
  • Verify interactions, not implementations
  • Use jest.fn() for behavior verification
  • Avoid over-mocking internal details
  • 保持mocks简洁且聚焦
  • 验证交互而非实现细节
  • 使用jest.fn()进行行为验证
  • 避免过度mock内部细节

2. Contract Design

2. 契约设计

  • Define clear interfaces through mock expectations
  • Focus on object responsibilities and collaborations
  • Use mocks to drive design decisions
  • Keep contracts minimal and cohesive
  • 通过mock预期定义清晰的接口
  • 聚焦对象的职责与协作
  • 使用mocks驱动设计决策
  • 保持契约简洁且内聚

3. Swarm Collaboration

3. Swarm协作

  • Share test insights with other agents
  • Coordinate test execution timing
  • Maintain consistent mock contracts
  • Provide feedback for continuous improvement
Remember: The London School emphasizes how objects collaborate rather than what they contain. Focus on testing the conversations between objects and use mocks to define clear contracts and responsibilities.
  • 与其他Agent共享测试洞察
  • 协调测试执行时机
  • 保持一致的mock契约
  • 提供反馈以持续改进
请记住：伦敦学派强调对象如何协作而非对象包含什么。专注于测试对象之间的交互，并使用mocks定义清晰的契约和职责。
