AutoFixture无法创建CreateAnonymous MVC Controller

Question

代码:

IFixture fixture = new Fixture().Customize(new AutoMoqCustomization());
fixture.Customize<ViewDataDictionary>(c => c.Without(x => x.ModelMetadata));
var target = fixture.CreateAnonymous<MyController>();

例外:

System.Reflection.TargetInvocationException:System.Reflection.TargetInvocationException:调用目标已抛出异常.---> System.NotImplementedException:未实现方法或操作.

MyController() 需要3个参数.

我试着在答案中描述的修复在这里,但它是行不通的.

Answer 1

看起来,在使用MVC 4时,您必须以Fixture不同的方式自定义实例.

如果您更换,测试应该通过:

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

用:

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

(可选)您可以创建所需自定义的组合:

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));
        }
    }
}

然后,原始测试可以重写为:

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

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

    Assert.IsAssignableFrom<IController>(sut);
}
