最小起订量 - 惩戒MVC控制器的Response.Cookies.Clear（） [英] MOQ - Mocking MVC Controller's Response.Cookies.Clear()

问题描述

我是新来的起订量，但使用它与NUnit的单元测试我。

I am new to MOQ, but am using it with NUnit for unit testing.

我有我的嘲笑控制器的所有部分，除了以下线，抛出一个'对象不设置到对象的实例错误信息。

I have all parts of my controller mocked, except the following line which throws an 'Object not set to an instance of an object' error message.

Response.Cookies.Clear();

我有以下的扩展方法来模拟它适用于一切我来翻过至今（非常感谢好心人对这个论坛）的控制器上下文。

I have the following extension method to mock the controller context which works for everything else I have come accross so far (very much thanks to the good people on this forum).

public static int SetUpForTest(this System.Web.Mvc.Controller ctl, string username, TestingUtility.Roles role)
    {
        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(Moq.It.IsAny<String>())).Returns((String url) => url);
        // response.SetupGet(x => x.Cookies).Returns(new HttpCookieCollection()); // This also failed to work

        var context = new Mock<HttpContextBase>(MockBehavior.Strict);
        context.SetupGet(x => x.Request).Returns(request.Object);
        context.SetupGet(x => x.Response).Returns(response.Object);
        context.SetupGet(x => x.Response.Cookies).Returns(new HttpCookieCollection()); // still can't call the Clear() method

        //
        // Mock the controller context (using the objects mocked above)
        //
        var moqCtx = new Mock<ControllerContext>(context.Object, new RouteData(), ctl);
        moqCtx.SetupGet(p => p.HttpContext.User.Identity.Name).Returns(username);
        moqCtx.SetupGet(p => p.HttpContext.User.Identity.IsAuthenticated).Returns(true);
        if (!string.IsNullOrEmpty(role.ToString()))
            moqCtx.Setup(p => p.HttpContext.User.IsInRole(role.ToString())).Returns(true);

        //
        // Pass the mocked ControllerContext and create UrlHelper for the controller and return
        //
        ctl.ControllerContext = moqCtx.Object;
        ctl.Url = new UrlHelper(new RequestContext(context.Object, new RouteData()), routes);
        return 1;
    }

正如你可以看到上面我试图嘲弄的Cookies集合，这不利于的'得到'。

As you can see above I have tried to mock the 'get' of the cookies collection, which does not help.

另外，实际的Clear（）方法不能嘲笑，因为它不是一个虚拟的方法。

Also, the actual Clear() method cannot be mocked as it is not a virtual method.

显然，我并不想测试的cookie被清除，我只是希望能够忽视它的测试。

Obviously I don't want to test that the cookies are being cleared, I just want to be able to ignore it in testing.

谢谢，

推荐答案

这工作对我来说，当我做cookies.Clear（）

This works for me when I do cookies.Clear()

            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(Moq.It.IsAny<String>())).Returns((String url) => url);
        // response.SetupGet(x => x.Cookies).Returns(new HttpCookieCollection()); // This also failed to work

        var context = new Mock<HttpContextBase>(MockBehavior.Strict);
        context.SetupGet(x => x.Request).Returns(request.Object);
        context.SetupGet(x => x.Response).Returns(response.Object);
        context.SetupGet(x => x.Response.Cookies).Returns(new HttpCookieCollection()); // still can't call the Clear() method
        context.SetupGet(p => p.User.Identity.Name).Returns("blah");
        context.SetupGet(p => p.User.Identity.IsAuthenticated).Returns(true);

        var rc = new RequestContext(context.Object, new RouteData());

        controller.ControllerContext = new ControllerContext(rc, controller);
