技术驱动的护城河：构建与世界级企业对标的产品研发管理体系指南

// 微服务架构示例代码
public class ProductService : IProductService
{
    private readonly IProductRepository _repository;
    
    // 依赖注入提升可测试性
    public ProductService(IProductRepository repository)
    {
        _repository = repository;
    }
    
    public async Task GetProductByIdAsync(int id)
    {
        // 异步操作提升系统吞吐量
        return await _repository.GetByIdAsync(id);
    }
    
    // 遵循单一职责原则
    public async Task UpdateProductPriceAsync(int id, decimal newPrice)
    {
        var product = await _repository.GetByIdAsync(id);
        if (product != null)
        {
            product.Price = newPrice;
            await _repository.UpdateAsync(product);
        }
    }
}

// 自动化测试示例 - Jest测试框架
describe('Product API Tests', () => {

    jest.resetAllMocks();
  });
  
  test('should return product details when valid ID provided', async () => {
    // 模拟依赖
    const mockProduct = { id: 1, name: 'Test Product', price: 99.99 };
    productService.getProductById = jest.fn().mockResolvedValue(mockProduct);
    
    // 执行测试
    const result = await productService.getProductById(1);
    
    // 断言验证
    expect(result).toEqual(mockProduct);
    expect(productService.getProductById).toHaveBeenCalledWith(1);
  });
  
  // 边界测试用例
  test('should throw error when product not found', async () => {
    productService.getProductById = jest.fn().mockRejectedValue(new Error('Product not found'));
    
    await expect(productService.getProductById(999)).rejects.toThrow('Product not found');
