11-3URLTestDemo
1、File -> New -> Project
在左边模板中选择Visual C#里的Web，对应到的项目类型选择ASP.NET MVC3 Web
Application，并给项目取名字为11-3URLTestDemo，默认的解决方案名自动为相应的11-3URLTestDemo。
2、在解决方案管理器中，鼠标右击解决方案名字Solution’ 11-3URLTestDemo’，选择Add -> New
Project，如下图。
打开“Add New Project”对话框后，在左边的模板选择Visual C#里的Test，对应的项目类型选择Test
Project，并取名字为URLTestDemo.UnitTests，如下图。
创建好项目后，可以将不用的Class1.cs文件和URLTestDemo.UnitTests项目中的UnitTest1.cs文件删除掉。
3、给URLTestDemo.UnitTests项目添加Moq程序包和对项目11-3URLTestDemo的依赖。
在URLTestDemo.UnitTests项目名上右击鼠标，选择Manage NuGet
Packages…，在打开的对话框中在线搜索Moq，并安装。再次在URLTestDemo.UnitTests项目名上右击鼠标，选择Add
Reference，在打开的对话框中选择对项目11-3URLTestDemo的依赖。
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。
