Using moq on an override of abstract method?

问题

I have this base class

public abstract class Third : IThird
{
    public abstract ThirdUser GetUserDetails(HttpRequestBase request);
}

and this derived class

public class LiProvider : Third
{
    public override ThirdUser GetUserDetails(HttpRequestBase request) { }
}

I tried to Moq this override like so:

mockLiProvider.Setup(x => x.GetUserDetails(It.IsAny<HttpRequestWrapper>())).Returns(user);

but it returns null, not the user in the Setup.

user is definitely initialised in this test.

How can I mock this?

回答1:

Shouldn't it be

mockLiProvider.Setup(x => x.GetUserDetails(It.IsAny<HttpRequestBase>())).Returns(user);

instead of

mockLiProvider.Setup(x => x.GetUserDetails(It.IsAny<HttpRequestWrapper>())).Returns(user);#

Notice the different type in It.IsAny<>, I've used HttpRequestBase instead of HttpRequestWrapper.

You example doesn't show how it is been called.

I wrote this simple test calling it like this:

mockLiProvider.Object
.GetUserDetails(new HttpRequestWrapper(new HttpRequest("a.txt","http://a.com","")));

and it works, with your version (HttpRequestWrapper). But if you are supplied some other derivative of HttpRequestBase the It.IsAny might not match the type.
