ASP.NET MVC - 单元测试RenderPartialViewToString（）与起订量的框架？

问题描述：

我使用这个helper方法把我的PartialViewResult成字符串并将其返回为JSON - http://www.atlanticbt.com/blog/asp-net-mvc-using-ajax-json-and-partialviews/

I'm using this helper method to turn my PartialViewResult into string and returning it as Json - http://www.atlanticbt.com/blog/asp-net-mvc-using-ajax-json-and-partialviews/

我的问题是，我使用起订量来模拟控制器，每当我运行单元测试使用这个RenderPartialViewToString（）方法中，我得到了对象引用不设置到对象的实例。错误的ControllerContext。

My problem is that I'm using Moq to mock the controller, and whenever I run unit test that uses this RenderPartialViewToString() method, I got the "Object reference not set to an instance of an object." error on ControllerContext.

private ProgramsController GetController()
{
var mockHttpContext = new Mock<ControllerContext>();
mockHttpContext.SetupGet(p => p.HttpContext.User.Identity.Name).Returns("test");
mockHttpContext.SetupGet(p => p.HttpContext.Request.IsAuthenticated).Returns(true);
// Mock Repositories
var mockOrganizationRepository = new MockOrganizationRepository(MockData.MockOrganizationsData());
var mockIRenderPartial = new BaseController();
var controller = new ProgramsController(mockOrganizationRepository, mockIRenderPartial);
controller.ControllerContext = mockHttpContext.Object;
return controller;
}

这会返回一个代理控制器，也许这就是为什么我得到这个错误的原因。任何想法如何单元测试呢？

This returns a proxy controller, and maybe it's the reason why I got that error. Any idea how to unit testing this?

非常感谢你。

试试这个：

public static void SetContext(this Controller controller)
        {
            var httpContextBase = new Mock<HttpContextBase>();
            var httpRequestBase = new Mock<HttpRequestBase>();
            var respone = new Mock<HttpResponseBase>();
            var session = new Mock<HttpSessionStateBase>();
            var routes = new RouteCollection();
            RouteConfigurator.RegisterRoutesTo(routes);

            httpContextBase.Setup(x => x.Response).Returns(respone.Object);
            httpContextBase.Setup(x => x.Request).Returns(httpRequestBase.Object);
            httpContextBase.Setup(x => x.Session).Returns(session.Object);
            session.Setup(x => x["somesessionkey"]).Returns("value");
            httpRequestBase.Setup(x => x.Form).Returns(new NameValueCollection());
            controller.ControllerContext = new ControllerContext(httpContextBase.Object, new RouteData(), controller);
            controller.Url = new UrlHelper(new RequestContext(controller.HttpContext, new RouteData()), routes);
        }
