如何模拟（有MOQ）统一方法 [英] How to Mock (with Moq) Unity methods

问题描述

扩展方法都没有测试好（这是这里描述的：<一href="http://stackoverflow.com/questions/2295960/mocking-extension-methods-with-moq">http://stackoverflow.com/questions/2295960/mocking-extension-methods-with-moq, <一href="http://www.clariusconsulting.net/blogs/kzu/archive/2009/12/22/Howtomockextensionmethods.aspx">http://www.clariusconsulting.net/blogs/kzu/archive/2009/12/22/Howtomockextensionmethods.aspx).

Extension methods are not good for testing (that's described here: http://stackoverflow.com/questions/2295960/mocking-extension-methods-with-moq, http://www.clariusconsulting.net/blogs/kzu/archive/2009/12/22/Howtomockextensionmethods.aspx).

但可能有一些解决方案，嘲讽的统一方法呢？在我的情况我有以下功能：

But probably there are some solutions for mocking of Unity methods? In my case I have the following function:

public class MyManager
{
    public MyManager(IUnityContainer container) : base(container) { }

    public IResult DoJob(IData data)
    {
        IMyLog log = MyContainer.Resolve<IMyLog>();

        ... use log.Id ...

        MyContainer.Resolve<...>();//usage for other purposes...
    }

我想，以确保'DoJob的方法总是会得到来自容器IMyLog的对象，而不是从其他渠道......我怎么能测试？

I want to be sure that 'DoJob' method will always get 'IMyLog' object from container, but not from other sources... how could I test that?

我最初的想法是改变DoJob法的实施和使用：

My original idea was to change 'DoJob' method implementation and use:

IMyLog log = UnityContainer.Resolve(typeof(IMyLog)) as IMyLog;

不过，解决（T型，...）也是一个扩展方法...

But 'Resolve(Type t, ...)' is also an extension method...

任何的想法是值得欢迎的。

Any thoughts are welcome.

P.S。请注意，我的日志对象从MyManager.DoJob ...

P.S. Please note, that 'my log' object is created far-away from MyManager.DoJob...

推荐答案

猜，我发现最合适的解决方案测试：这是没有必要的模拟团结容器，并检查日志对象是从它拍摄。我只想做一个模拟的日志的对象，在容器中注册其对象实例和检查测试，如果该日志对象真正使用。

Guess, I found most appropriate solution for test: It is not necessary to mock unity container and check if 'log' object was taken from it. I will just make a mock for 'Log' object, register its object instance in the container and check in test if this log object is really used.

这将做什么是必需的。

        Mock<IMyLog> mockLog = new Mock<IMyLog>();
        mockLog.Setup(mock=>mock.Id).Returns(TestLogId);

        IUnityContainer container = new UnityContainer();
        container
            .RegisterInstance(mockCommandExecutionLog.Object)
            ...
            ;

        ...

        mockLog.Verify(
            mock => mock.Id,
            Times.Once(),
            "It seems like 'Log' object is not used"
            );
