我如何使用 Rhino.Mocks 来模拟 ControllerContext

问题描述

我正在尝试使用 Rhino.Mocks 来模拟一个 ControllerContext 对象，以访问我的控制器单元中的运行时对象，如用户、请求、响应和会话测试.我编写了以下方法以尝试模拟控制器.

I am trying to use Rhino.Mocks to mock up a ControllerContext object to gain access to runtime objects like User, Request, Response, and Session in my controller unit tests. I've written the below method in an attempt to mock up a controller.

private TestController CreateTestControllerAs(string userName)
{
    var mock = MockRepository.GenerateStub<ControllerContext>();
    mock.Stub(con =>
        con.HttpContext.User.Identity.Name).Return(userName);
    mock.Stub(con =>
        con.HttpContext.Request.IsAuthenticated).Return(true);

    var controller = CreateTestController(); // left out of example for brevity
    controller.ControllerContext = mock;

    return controller;
 }

但是，我模拟的 ControllerContext 的 HttpContext 为空，并且我尝试访问 HttpContext.User 等会导致 System.NullReferenceException.

However, the HttpContext of my mocked ControllerContext is null and there my attempts to access HttpContext.User etc. cause a System.NullReferenceException.

我的嘲讽做错了什么?

推荐答案

我强烈建议您查看 MVCContrib.TestHelper 使用 Rhino.Mocks 并提供一种优雅的方式来测试您的控制器.您的测试可能如下所示:

I would strongly recommend you looking at MVCContrib.TestHelper which uses Rhino.Mocks and provides an elegant way to test your controllers. Here's how your test might look like:

[TestClass]
public class UsersControllerTests : TestControllerBuilder
{
    [TestMethod]
    public void UsersController_Index()
    {
        // arrange
        // TODO : this initialization part should be externalized
        // so that it can be reused by other tests
        var sut = new HomeController();
        this.InitializeController(sut);
        // At this point sut.Request, sut.Response, sut.Session, ... are
        // stubed objects on which you could define expectations.

        // act
        var actual = sut.Index();

        // assert
        actual.AssertViewRendered();
    }
}

这是一个单元测试 对于 控制器是我编写的 示例 ASP.NET MVC 应用程序的一部分.

And here's an unit test for a controller that is part of a sample ASP.NET MVC application I wrote.
