如何使用静态方法最小起订量静态类（UnitOfWork 情况）？

我有这些课程：

public static class UnitOfWorkSS 
{
  public static IUnitOfWork Begin()
  {
    return IoC.Resolve<IUnitOfWork>();
  }
}

public class PostService
{
  using (IUnitOfWork unitOfWork = UnitOfWorkSS.Begin())
  {
    //don't forget to sanitize html content
    htmlContent = _htmlSanitizer.Sanitize(htmlContent);

    IPost post = _factory.CreatePost(byUser, title, htmlContent);                    

    _postRepository.Add(post);

    unitOfWork.Commit();
  }
}

我怎样才能模拟课程UnitOfWorkSS and unitOfWork?

看起来您调用 Begin() 所做的唯一一件事就是返回该特定接口的配置类：IUnitOfWork

您实际上只需要确保对 Begin() 的调用返回一个模拟实现IUnitOfWork

您可以通过以下两种方法之一执行此操作：

选项一- 重构UnitOfWorkSS这样你就可以设置实例IUnitOfWork待退回

public static class UnitOfWorkSS  
{
    private static IUnitOfWork _unitOfWork;
    public static IUnitOfWork UnitOfWork
    {
        set { _unitOfWork = value; }
        private get{ _unitOfWork ?? (_unitOfWork = IoC.Resolve<IUnitOfWork>()); }
    }

    public static IUnitOfWork Begin()  
    {  
        return UnitOfWork;
    }  
}  

[TestMethod]
public void DoStuff()
{
    var mockUnitOfWork = new Mock<IUnitOfWork>();
    UnitOfWorkSS.UnitOfWork = mockUnitOfWork.Object;

    //Do some setup and verify
}

选项二- 只需注册一个模拟实例IUnitOfWork与你的 IoC 容器

private Mock<IUnitOfWork> _mockUnitOfWork;

[TestInitialize]
public void Init()
{
    _mockUnitOfWork = new Mock<IUnitOfWork>();

    //Making a lot of assumptions about your IoC here...
    IoC.Register<IUnitOfWork>(_mockUnitOfWork.Object);
}

[TestMethod]
public void DoStuff()
{
    _mockUnitOfWork.Setup( ... );

    //Do some verification
}
