Mocking class with no parameterless ctor

[Mardoxx]

Has this been considered?

public class MockMe
{
    MockMe(ISomeDependency someDependency)
    {
    }

    MockMe(ISomeDependency someDependency, ISomeOtherThing someOtherThing)
    {
    }
}

Would be nice to be able to do new Mock<MockMe>(); without having to specify params.
Maybe have it choose simplest ctor (least num params) and then attempt to throw in mocks of these parameters (or default values).

Here new Mock<MockMe>(); would be equiv of new Mock<MockMe>(Mock.Of<ISomeDependency>());

Moq is not a DI container and as far as I am aware, it doesn't strive to be one. If we added this functionality to Moq, it would either be very incomplete (when compared to a proper DI container), or we'd have to bring in a lot of functionality that has nothing to do with mocking. Both outcomes are equally undesirable.

It would be much better, IMO, to build this functionality / integration outside of the core library. Say, create a helper function that analyzes the desired type's parameters, fetches appropriate values from somewhere else, then invokes the Mock<T> ctor with these values.

If you don't want to build this yourself, I'm sure there are existing projects that do this kind of thing for you -- AutoFixture and Moq.AutoMock come to mind.

That's exactly what I was looking for, thanks so much 😄
