单元测试RenderMvcController甚至可能吗？

Question

所以我正在使用Umbraco 6.12并且很难测试一个RenderMvcController.

我已经IApplicationEventHandler在我Global.ascx和Ninject中实现了正常运行并且正如预期的那样运行应用程序 - 一切都很好.

但是,对这些控制器进行单元测试是另一回事.我发现了这个,并添加了最新的回复:

http://issues.umbraco.org/issue/U4-1717

我现在在我的SetUp中有这个可爱的黑客:

 Umbraco.Web.UmbracoContext.EnsureContext(new HttpContextWrapper(new HttpContext(new HttpRequest("", "http://www.myserver.com", ""), new HttpResponse(null))), ApplicationContext.Current);

哪个已经绕过原来UmbracoContext不能为空,但现在抛出:

当前尚未在Umbraco.Web.PublishedCache.PublishedCachesResolver上初始化.您必须在尝试读取之前初始化Current.

已发布的缓存解析器似乎也隐藏在内部和受保护的东西之后,我无法使用反射来破解,因为我无法初始化SetProperty反射.

这真的令人沮丧,我喜欢v6,使用uMapper非常好.我可以随意将一个回购,服务,命令或查询注入控制器,生活很美好 - 我无法覆盖控制器!

任何有关这方面的帮助将不胜感激.

谢谢.

要对Umbraco RenderMvcController进行单元测试,您需要从github获取源代码,自己编译解决方案,并获取Umbraco.Tests.dll并在测试项目中引用它.

除此之外,您还需要引用随Umbraco软件包一起分发的SQLCE4Umbraco.dll和内部用于模拟的Rhino.Mocks.dll.

为了帮助你,我已经编译了Umbraco.Tests.dll用于Umbraco 6.1.5并将它与Rhino.Mocks.dll放在一起并将它放在这个zip文件中.

最后,从BaseRoutingTest派生您的测试,将DatabaseTestBehavior覆盖到NoDatabasePerFixture,并通过调用GetRoutingContext方法获取UmbracoContext和HttpBaseContext,如下面的代码所示:

using System;
using Moq;
using NUnit.Framework;
using System.Globalization;
using System.Web.Mvc;
using System.Web.Routing;
using Umbraco.Core.Models;
using Umbraco.Tests.TestHelpers;
using Umbraco.Web;
using Umbraco.Web.Models;
using Umbraco.Web.Mvc;

namespace UnitTests.Controllers
{
    public class Entry
    {
        public int Id { get; set; }
        public string Url { get; set; }
        public string Title { get; set; }
        public string Summary { get; set; }
        public string Content { get; set; }
        public string Author { get; set; }
        public string[] Tags { get; set; }
        public DateTime Date { get; set; }
    }

    public interface IBlogService
    {
        Entry GetBlogEntry(int id);
    }

    public class BlogEntryController : RenderMvcController
    {
        private readonly IBlogService _blogService;

        public BlogEntryController(IBlogService blogService, UmbracoContext ctx)
            : base(ctx)
        {
            _blogService = blogService;
        }

        public BlogEntryController(IBlogService blogService)
            : this(blogService, UmbracoContext.Current)
        {
        }

        public override ActionResult Index(RenderModel model)
        {
            var entry = _blogService.GetBlogEntry(model.Content.Id);

            // Test will fail if we return CurrentTemplate(model) as is expecting 
            // the action from ControllerContext.RouteData.Values["action"]
            return View("BlogEntry", entry);
        }
    }

    [TestFixture]
    public class RenderMvcControllerTests : BaseRoutingTest
    {
        protected override DatabaseBehavior DatabaseTestBehavior
        {
            get { return DatabaseBehavior.NoDatabasePerFixture; }
        }

        [Test]
        public void CanGetIndex()
        {
            const int id = 1234;
            var content = new Mock<IPublishedContent>();
            content.Setup(c => c.Id).Returns(id);
            var model = new RenderModel(content.Object, CultureInfo.InvariantCulture);
            var blogService = new Mock<IBlogService>();
            var entry = new Entry { Id = id };
            blogService.Setup(s => s.GetBlogEntry(id)).Returns(entry);
            var controller = GetBlogEntryController(blogService.Object);

            var result = (ViewResult)controller.Index(model);

            blogService.Verify(s => s.GetBlogEntry(id), Times.Once());
            Assert.IsNotNull(result);
            Assert.IsAssignableFrom<Entry>(result.Model);
        }

        private BlogEntryController GetBlogEntryController(IBlogService blogService)
        {
            var routingContext = GetRoutingContext("/test");
            var umbracoContext = routingContext.UmbracoContext;
            var contextBase = umbracoContext.HttpContext;
            var controller = new BlogEntryController(blogService, umbracoContext);
            controller.ControllerContext = new ControllerContext(contextBase, new RouteData(), controller);
            controller.Url = new UrlHelper(new RequestContext(contextBase, new RouteData()), new RouteCollection());
            return controller;
        }
    }
}

此代码仅在Umbraco 6.1.5中进行了测试.
