Creating a dummy for a type with PRIVATE default constructor

Currently when FakeItEasy goes to make a type with a private constructor we just get back null and no warnings / exceptions.

Here’s a test:

public interface Thing { }

public interface Foo
{
    Task<TThing> Bar<TThing>() where TThing : Thing;
}

public class FakeThing : Thing {
    private FakeThing() { }
}

[Fact]
public async Task Test1()
{
    var foo = A.Fake<Foo>();
    var bar = await foo.Bar<FakeThing>();

    Assert.NotNull(bar);
}    

Personally - I’d like to see a real dummy actually be created. Just because the constructor is private shouldn’t prevent a dummy from being created. In my app I make users define aggregate root’s as private constructor so a new developer doesn’t go and do var entity = new InvoiceAggregateRoot() so there is a real use case for creating these objects even though they’re marked private.

But the bug is IMO if this behavior is not supported it should throw a “Could not create dummy” exception - not just return null like everything is fine.

@novak, the ability to configure all of a Fake’s members to return values from AutoFixture can be accessed like this:

var fixture = new Fixture().Customize(new AutoFakeItEasyCustomization { ConfigureMembers = true });

I can’t find proper user documentation for it, but you can see the API Docs on the wonderful fuget.

I’m glad you’re up and running, @volak.
