我们不得不
HttpContext通过使用a
HttpContextManager并从应用程序以及单元测试中调用工厂来进行模拟
public class HttpContextManager { private static HttpContextbase m_context; public static HttpContextbase Current { get { if (m_context != null) return m_context; if (HttpContext.Current == null) throw new InvalidOperationException("HttpContext not available"); return new HttpContextWrapper(HttpContext.Current); } } public static void SetCurrentContext(HttpContextbase context) { m_context = context; }}然后，将取代任何调用
HttpContext.Current与
HttpContextManager.Current并有机会获得同样的方法。然后，当您进行测试时，您还可以访问
HttpContextManager并模拟您的期望
这是使用Moq的示例：
private HttpContextbase GetMockedHttpContext(){ 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>(); var user = new Mock<IPrincipal>(); var identity = new Mock<IIdentity>(); var urlHelper = new Mock<UrlHelper>(); var routes = new RouteCollection(); MvcApplication.RegisterRoutes(routes); var requestContext = new Mock<RequestContext>(); requestContext.Setup(x => x.HttpContext).Returns(context.Object); 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); context.Setup(ctx => ctx.User).Returns(user.Object); user.Setup(ctx => ctx.Identity).Returns(identity.Object); identity.Setup(id => id.IsAuthenticated).Returns(true); identity.Setup(id => id.Name).Returns("test"); request.Setup(req => req.Url).Returns(new Uri("http://www.google.com")); request.Setup(req => req.RequestContext).Returns(requestContext.Object); requestContext.Setup(x => x.RouteData).Returns(new RouteData()); request.SetupGet(req => req.Headers).Returns(new NamevalueCollection()); return context.Object;}然后在单元测试中使用它，我在Test Init方法中调用它
HttpContextManager.SetCurrentContext(GetMockedHttpContext());
然后，您可以在上述方法中，将期望从Session中获得的预期结果添加到Web服务中。
