asp.net-mvc – 尝试使用Moq模拟HtmlHelper时抛出MissingMethodException

当试图遵循 article on mocking the htmlhelper with Moq时,我遇到了以下问题.创建htmlhelper时会抛出异常.我只是猜测正在使用城堡windsor(通过查看错误消息).

例外：

MissingMethodException occurred

Constructor on type ‘Castle.Proxies.ViewContextProxy’ not found.

堆栈跟踪：

at System.RuntimeType.CreateInstanceImpl(BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes)

代码：

public static HtmlHelper CreateHtmlHelper(ViewDataDictionary vd)
    {
        Mock<ViewContext> mockViewContext = new Mock<ViewContext>(
                                                new ControllerContext(
                                                    new Mock<HttpContextBase>().Object,
                                                    new RouteData(),
                                                    new Mock<ControllerBase>().Object),
                                                new Mock<IView>().Object,
                                                vd,
                                                new TempDataDictionary());

        Mock<IViewDataContainer> mockViewDataContainer = new Mock<IViewDataContainer>();
        mockViewDataContainer.Setup(v => v.ViewData).Returns(vd);

        return new HtmlHelper(mockViewContext.Object, mockViewDataContainer.Object);
    }

我正在使用ASP MVC 2,Moq 4.0 beta 3,VS2010,使用IDE的测试框架.

如何解决问题并返回HtmlHelper的实例？

我已经通过我的博客文章中的代码重现了您的问题.以下更新的方法适用于我：

public static HtmlHelper CreateHtmlHelper(ViewDataDictionary vd)
{
    Mock<ViewContext> mockViewContext = new Mock<ViewContext>(
        new ControllerContext(
            new Mock<HttpContextBase>().Object,
            new RouteData(),
            new Mock<ControllerBase>().Object),
        new Mock<IView>().Object,
        vd,
        new TempDataDictionary(),
        new Mock<TextWriter>().Object);

    mockViewContext.Setup(vc => vc.ViewData).Returns(vd);

    var mockViewDataContainer = new Mock<IViewDataContainer>();
    mockViewDataContainer.Setup(v => v.ViewData)
        .Returns(vd);

    return new HtmlHelper(mockViewContext.Object,
                            mockViewDataContainer.Object);
}

我也发布了一个update on my blog.
