在写单元测试时发现UnitOfWorkManager不能被Moq库Mock, 你们有更好的做法吗?

代码

var mockUnitOfWorkManager = new Mock<UnitOfWorkManager>();
mockUnitOfWorkManager.Setup(r => r.Begin(Propagation.Required, null));

错误

System.NotSupportedException: Unsupported expression: r => r.Begin(Propagation.Required, null)
Non-overridable members (here: UnitOfWorkManager.Begin) may not be used in setup / verification expressions.

public IUnitOfWork Begin(Propagation propagation = Propagation.Required, IsolationLevel? isolationLevel = null)

原型是这样定义的，定义固定的变量再传试试，不要用 null

这个问题的原因是Moq只能模拟可重写的成员(如接口方法、抽象方法、虚方法), 而 UnitOfWorkManager.Begin 方法是一个非虚（non-virtual）方法，因此 Moq 无法对其进行 Setup 配置。

有办法为UnitOfWorkManager类添加一个接口(IUnitOfWorkManager)? 或者有什么别的写法？

如果不能等，可以用适配器模式解决，自己定义新的 IUnitOfWorkManager、UnitOfWorkManagerImpl
下个版本吧，我补充 IUnitOfWorkManager

不着急, 谢谢大佬
