MVC单元测试单选按钮帮助扩展

Question

在我的另一个问题中，我得到了一个非常好的答案:

using System;
using System.Linq.Expressions;
using System.Web;
using System.Web.Mvc;
using System.Web.Mvc.Html;
public static class RadioExtensions
{ 
    public static IHtmlString MyRadioButtonFor<TModel, TProperty>(
        this HtmlHelper<TModel> html,
        Expression<Func<TModel, TProperty>> ex,
        object value
    )
    {
        var isAuthenticated = html.ViewContext.HttpContext.User.Identity.IsAuthenticated;
        if (isAuthenticated)
        {
            return html.RadioButtonFor(ex, value);
        }
        return html.RadioButtonFor(ex, value, new { @disabled = "disabled" });
    }
}

无论如何，我想对这个进行单元测试:

[Test]
        public void RadioButtonHelper()
        {
            var cc = new Mock<ControllerContext>(
                new Mock<HttpContextBase>(),
                new RouteData(),
                new Mock<ControllerBase>());
            var mockViewContext = new Mock<ViewContext>(
                cc,
                new Mock<IView>(),
                new TempDataDictionary());
            var mockViewDataContainer = new Mock<IViewDataContainer>();
            HtmlHelper helper = new HtmlHelper(mockViewContext.Object, mockViewDataContainer.Object);
            helper.
        }

当我到达调用方法的部分时，我无法到达该方法。

有人知道怎么做吗?

Answer 1

尝试在顶部将命名空间作为using包含到扩展中。

要测试静态帮助器，只需执行以下操作

[Test]
public void MyHelperTests()
{
  HtmlHelper html = null;
  var result = html.MyRadioButtonFor(/* your params */);
  Assert.IsInstanceOfType(typeof(MvcHtmlString), result);
  Assert.AreEqual(/* your results */, result.ToString());
}
