This is an update to my previous post on mocking HtmlHelper way back when ASP.NET MVC RC1 was released. Eric notified me through a comment on the post and a question on StackOverflow that the code for ASP.NET MVC RC1 did not work with ASP.NET MVC 2. The code in this post should work with ASP.NET MVC 2 and ASP.NET MVC 3 Preview 1.


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);
    var mockViewDataContainer = new Mock<IViewDataContainer>();
    mockViewDataContainer.Setup(v => v.ViewData)
        .Returns(vd);
    return new HtmlHelper(mockViewContext.Object,
                            mockViewDataContainer.Object);
}

The ViewDataDictionary that is passed to the HtmlHelper can be empty, or made to contain the data you want for your test.


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

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

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