ASP.NET MVC:使用UrlHelper的单元测试控制器

我的一个控制器操作,一个在Ajax请求中被调用,正在向客户端返回一个URL,以便它可以进行重定向.我正在使用Url.RouteUrl(..)并且在我的单元测试期间由于Controller.Url参数未预先填充而失败.

我尝试了很多东西,其中包括尝试存根UrlHelper(失败),手动创建一个UrlHelper带有RequestContext存根HttpContextBase(在RouteCollection.GetUrlWithApplicationPath调用时失败)的存根.

我搜索了谷歌,但几乎没有发现这个问题.我Url.RouteUrl在Controller操作中使用了一些非常愚蠢的东西吗？有没有更简单的方法？

更糟糕的是,我希望能够在我的单元测试中测试返回的URL - 实际上我只是想知道它重定向到正确的路由,但是因为我正在返回一个URL而不是一个URL route,我想控制解析的URL(例如,通过使用stubbed RouteCollection) - 但我很乐意让我的测试通过开始.

这是我的一个测试(xUnit + Moq),仅用于类似的情况(在控制器中使用Url.RouteUrl)

希望这可以帮助:

var routes = new RouteCollection();
MvcApplication.RegisterRoutes(routes);

var request = new Mock(MockBehavior.Strict);
request.SetupGet(x => x.ApplicationPath).Returns("/");
request.SetupGet(x => x.Url).Returns(new Uri("http://localhost/a", UriKind.Absolute));
request.SetupGet(x => x.ServerVariables).Returns(new System.Collections.Specialized.NameValueCollection());

var response = new Mock(MockBehavior.Strict);
response.Setup(x => x.ApplyAppPathModifier("/post1")).Returns("http://localhost/post1");

var context = new Mock(MockBehavior.Strict);
context.SetupGet(x => x.Request).Returns(request.Object);
context.SetupGet(x => x.Response).Returns(response.Object);

var controller = new LinkbackController(dbF.Object);
controller.ControllerContext = new ControllerContext(context.Object, new RouteData(), controller);
controller.Url = new UrlHelper(new RequestContext(context.Object, new RouteData()), routes);

var context = new Mock();
var request = new Mock();
var response = new Mock();
var session = new Mock();
var server = new Mock();

context.Setup(ctx => ctx.Request).Returns(request.Object);
context.Setup(ctx => ctx.Response).Returns(response.Object);
context.Setup(ctx => ctx.Session).Returns(session.Object);
context.Setup(ctx => ctx.Server).Returns(server.Object);

request.SetupGet(x => x.ApplicationPath).Returns("/");
request.SetupGet(x => x.Url).Returns(new Uri("http://localhost/a", UriKind.Absolute));
request.SetupGet(x => x.ServerVariables).Returns(new NameValueCollection());

response.Setup(x => x.ApplyAppPathModifier(It.IsAny())).Returns(x => x);

context.SetupGet(x => x.Request).Returns(request.Object);
context.SetupGet(x => x.Response).Returns(response.Object);

var routes = new RouteCollection();
MvcApplication.RegisterRoutes(routes);
var helper = new UrlHelper(new RequestContext(context.Object, new RouteData()), routes);
