AutoFixture fails to CreateAnonymous MVC Controller

by

As it seems, when using MVC 4 you have to customize the Fixture instance in a different way.

The test should pass if you replace:

fixture.Customize<ViewDataDictionary>(c => c
    .Without(x => x.ModelMetadata));

with:

fixture.Customize<ControllerContext>(c => c
    .Without(x => x.DisplayMode));

Optionally, you can create a composite of the required customizations:

internal class WebModelCustomization : CompositeCustomization
{
    internal WebModelCustomization()
        : base(
            new MvcCustomization(),
            new AutoMoqCustomization())
    {
    }

    private class MvcCustomization : ICustomization
    {
        public void Customize(IFixture fixture)
        {
            fixture.Customize<ControllerContext>(c => c
                .Without(x => x.DisplayMode));
        }
    }
}

Then, the original test could be rewritten as:

[Fact]
public void Test()
{
    var fixture = new Fixture()
        .Customize(new WebModelCustomization());

    var sut = fixture.CreateAnonymous<MyController>();

    Assert.IsAssignableFrom<IController>(sut);
}
