How to Unit Test HtmlHelper with Moq?

Here’s another article that shows you how to achieve the same thing:

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());

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

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