4、本例是为了对URL做单元测试，在11-3URLTestDemo项目中，打开Global.asax.cs文件，将RegisterRoutes函数修改如下：
public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute("MyRoute", "{controller}/{action}"); } |
然后再在RegisterRoutes函数上点鼠标右键，选择Create Unit Tests，创建单元测试的文件，这里就会在项目URLTestDemo.UnitTests中产生一个名字为
MvcApplicationTest.cs的文件，打开该文件，将MvcApplicationTest类中的原有内容删除，修改如下： namespace URLTestDemo.UnitTests { [TestClass()] public class MvcApplicationTest { private HttpContextBase CreateHttpContext(string targetUrl=null, string httpMethod = "GET") { Mock<HttpRequestBase> mockRequest = new Mock<HttpRequestBase>(); mockRequest.Setup(m => m.AppRelativeCurrentExecutionFilePath).Returns(targetUrl); mockRequest.Setup(m => m.HttpMethod).Returns(httpMethod); Mock<HttpResponseBase> mockResponse = new Mock<HttpResponseBase>(); mockResponse.Setup(m => m.ApplyAppPathModifier( It.IsAny<string>())).Returns<string>(s => s); Mock<HttpContextBase> mockContext = new Mock<HttpContextBase>(); mockContext.Setup(m => m.Request).Returns(mockRequest.Object); mockContext.Setup(m => m.Response).Returns(mockResponse.Object); return mockContext.Object; } private void TestRouteMatch(string url, string controller, string action, object routeProperties = null, string httpMethod = "GET") { //布置 RouteCollection routes = new RouteCollection(); MvcApplication.RegisterRoutes(routes); //动作 RouteData result = routes.GetRouteData(CreateHttpContext(url, httpMethod)); //断言 Assert.IsNotNull(result); Assert.IsTrue(TestIncomingRouteResult(result, controller, action, routeProperties)); } private bool TestIncomingRouteResult(RouteData routeResult, string controller, string action, object propertySet = null) { Func<object, object, bool> valCompare = (v1, v2) => { return StringComparer.InvariantCultureIgnoreCase.Compare(v1, v2) == 0; }; bool result = valCompare(routeResult.Values["controller"], controller) && valCompare(routeResult.Values["action"], action); if (propertySet != null) { PropertyInfo[] propInfo = propertySet.GetType().GetProperties(); foreach (PropertyInfo pi in propInfo) { if (!(routeResult.Values.ContainsKey(pi.Name) && valCompare(routeResult.Values[pi.Name], pi.GetValue(propertySet, null)))) { result = false; break; } } } return result; } private void TestRouteFail(string url) { //布置 RouteCollection routes = new RouteCollection(); MvcApplication.RegisterRoutes(routes); //动作 RouteData result = routes.GetRouteData(CreateHttpContext(url)); //断言 Assert.IsTrue(result == null || result.Route == null); } [TestMethod] public void TestIncomingRoutes() { TestRouteMatch("~/Admin/Index", "Admin", "Index"); TestRouteMatch("~/One/Two", "One", "Two"); TestRouteFail("~/Admin/Index/Segment"); TestRouteFail("~/Admin"); } } } |
5、接下来，在菜单上选择Test -> Run -> All Tests in Solution，执行单元测试。
