ASP.NET MVC：使用UrlHelper的单元测试控制器

5 回答

• 34

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

  来自eu-ge-ne的改进实现 . 这个返回基于应用程序中定义的路由生成的链接 . eu-ge-ne的例子总是返回一个固定的响应 . 下面的方法将允许您测试正确的操作/控制器和路由信息是否正在传递到UrlHelper - 如果您正在测试对UrlHelper的调用，那么这就是您想要的 .

  var context = new Mock<HttpContextBase>();
  var request = new Mock<HttpRequestBase>();
  var response = new Mock<HttpResponseBase>();
  var session = new Mock<HttpSessionStateBase>();
  var server = new Mock<HttpServerUtilityBase>();
  
  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<string>())).Returns<string>(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);

  如果你想模拟HttpContextBase类，这篇文章可能会有用 .

  Build @ eu-ge-ne的答案给了我很多帮助：

  我有一个ActionResult，它执行了重定向，并且使用FormCollection参数进行了UpdateModel调用 . 要使UpdateModel（）起作用，我必须将它添加到我的Mocked HttpRequestBase中：

  FormCollection collection = new FormCollection();
  collection["KeyName"] = "KeyValue";
  
  request.Setup(x => x.Form).Returns(collection);
  request.Setup(x => x.QueryString).Returns(new NameValueCollection());
  

  要测试重定向的URL是否正确，您可以执行以下操作：

  RedirectResult result = controller.ActionName(modelToSubmit, collection) as RedirectResult;
  Assert.AreEqual("/Expected/URL", result.Url);

  http://kbochevski.blogspot.com/2010/06/unit-testing-mvcnet.html讨论了如何使用单元测试覆盖所有层 . 它使用Rhino和MVC.Contrib进行控制器测试 . 谷歌上的源代码可能会有很大的帮助 .
