Question

在我的另一个问题中，我得到了一个帮助方法的非常好的答案：

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，我试图对此进行单元测试：

[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，我无法使用该方法。

任何人都知道怎么做？

Answer 1

尝试将名称空间包含在扩展名中，作为using位于顶部。

要测试你的静态助手，只需做这样的事情

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

MVC单元测试RadioButton Helper扩展
