问题
I want to test a method to check that it saves a transaction correctly. Inside it calls Membership.GetUser() to verify the user which causes the test to fail each time. Is there any way to mock this so that Membership.GetUser() always returns a valid name?
I'm using Moq, C# and ASP.Net 4.5 MVC
回答1:
In short, you can't. That's why every call to such a "service" should be hidden behind an abstraction.
You can see a sample of that in default MVC template.

Yes, like Serg said, you can mock this by providing an interface for the real service to implement. This interface would have the public methods you are calling, such as:
public interface IMyServiceInterface
{
IMembershipUser GetUser();
// other methods you want to use...
}
In your unit tests, you would say:
var mockService = new Mock<IServiceInterface>();
mockService.Setup(mock => mock.GetUser()).
Returns(new MembershipUserImplementation("MyTestUser", otherCtorParams));
In my example I would create a wrapper for MembershipUser as well as it seems like it also needs to be behind an abstraction.
