在模拟的 HttpContextBase 上设置属性

我正在开发一个 ASP.NET MVC 应用程序，并尝试针对控制器操作编写一些单元测试，其中一些操作 HttpContext 上的属性，例如 Session、Request.Cookies、Response.Cookies 等。在弄清楚如何“排列、操作、断言”时遇到一些麻烦...我可以看到排列和断言...但是当模拟的 HttpContextBase 的所有属性都已设置时，我无法弄清楚如何对模拟的 HttpContextBase 的属性进行“操作”只有吸气剂。我不能set我的控制器操作中的模拟上下文中的任何内容......所以它看起来不是很有用。我对模拟相当陌生，所以我确信我缺少一些东西，但对我来说，我应该能够创建一个模拟对象，我可以在测试控制器操作的上下文中使用它，这似乎是合乎逻辑的实际上可以set属性值，然后断言它们仍然是我设置的值，或者类似的东西。我缺少什么？

    public static HttpContextBase GetMockHttpContext()
    {
        var requestCookies = new Mock<HttpCookieCollection>();
        var request = new Mock<HttpRequestBase>();
        request.Setup(r => r.Cookies).Returns(requestCookies.Object);
        request.Setup(r => r.Url).Returns(new Uri("http://example.org"));

        var responseCookies = new Mock<HttpCookieCollection>();
        var response = new Mock<HttpResponseBase>();
        response.Setup(r => r.Cookies).Returns(responseCookies.Object);

        var context = new Mock<HttpContextBase>();

        context.Setup(ctx => ctx.Request).Returns(request.Object);
        context.Setup(ctx => ctx.Response).Returns(response.Object);
        context.Setup(ctx => ctx.Session).Returns(new Mock<HttpSessionStateBase>().Object);
        context.Setup(ctx => ctx.Server).Returns(new Mock<HttpServerUtilityBase>().Object);
        context.Setup(ctx => ctx.User).Returns(GetMockMembershipUser());
        context.Setup(ctx => ctx.User.Identity).Returns(context.Object.User.Identity);
        context.Setup(ctx => ctx.Response.Output).Returns(new StringWriter());

        return context.Object;
    }

不确定是否有人感兴趣，但我已经使用 Rhino Mocks（我选择的武器）将 Moq FakeHttpContext 转换为一个。

public static HttpContextBase FakeHttpContext()
        {
            var httpContext = MockRepository.GenerateMock<HttpContextBase>();
            var request = MockRepository.GenerateMock<HttpRequestBase>();
            var response = MockRepository.GenerateMock<HttpResponseBase>();
            var session = MockRepository.GenerateMock<HttpSessionStateBase>();
            var server = MockRepository.GenerateMock<HttpServerUtilityBase>();
            var cookies = new HttpCookieCollection();
            response.Stub(r => r.Cookies).Return(cookies);
            request.Stub(r => r.Cookies).Return(cookies);
            request.Stub(r => r.Url).Return(new Uri("http://test.com"));

            httpContext.Stub(x => x.Server).Return(server);
            httpContext.Stub(x => x.Session).Return(session);
            httpContext.Stub(x => x.Request).Return(request);
            httpContext.Stub(x => x.Response).Return(response);
            var writer = new StringWriter();
            var wr = new SimpleWorkerRequest("", "", "", "", writer);
            System.Web.HttpContext.Current = new System.Web.HttpContext(wr);
            return httpContext;

        }

单元测试中的用法为

_httpContext = FakeHttpContext();
var cookieManager = new CookieManager(_httpContext);
string username = cookieManager.GetUsername();
_httpContext.AssertWasCalled(hc => { var dummy = hc.Request; });
