我开始与NHibernate，ASP.NET MVC 2.0和StructureMap一个新的项目，并使用NUnit和起订量进行检测。对于我的每个控制器我有一个单一的公共构造成一个ISession被注入。该应用程序本身工​​作得很好，但在单元测试方面，我基本上都嘲笑一个ISession为了测试控制器。

当我试图嘲弄的ISession与MOQ我收到以下错误消息：

只有属性访问支持   中间调用

看来，我的问题是希望从框架的createQuery方法的用户列表中，但使用Google发出后，我现在更清楚。

我有两个问题：

1），这是错误的方式来嘲笑依赖注入一个ISession的

2）有没有办法来修改code，以便它可以成功返回我的列表

请注意，我是pretty的肯定，我可以只创建用户的硬codeD列表（而不是嘲讽单个用户并将其添加到列表中），但想我会离开的code，因为我有现在。

此外，这个特殊的控制器的索引动作基本上执行的createQuery调用模仿上面返回所有数据库中的用户。这是一个人为的例子 - 不读任何东西到细节

在此先感谢您的帮助

编辑：在回答下面的评论，我加入的堆栈跟踪的错误。此外，在用户类的所有属性都是虚拟的。

下面是解决方案，我想出了这似乎很好地工作。同样，我不测试NHibernate和我没有测试数据库 - 我只是想测试依赖于NHibernate的控制器。与最初的解决方案，这个问题似乎是事实，我是调用一个方法，以及在读的起订量建立呼叫会话的列表成员。我分手了这些呼叫通过打破解成QueryMock和会话模拟（创建查询返回IQUERY对象）。事务模拟也是必要的，因为它是一个依赖（在我的情况）的会议......

I am starting a new project with NHibernate, ASP.NET MVC 2.0 and StructureMap and using NUnit and Moq for testing. For each of my controllers I have a single public constructor into which an ISession is being injected. The application itself works just fine, but in terms of unit testing I essentially have to mock an ISession in order to test the controllers.

When I attempt to Mock the ISession with MOQ i get the following error message:

Only property accesses are supported in intermediate invocations

It appears that my problem is expecting List of users from the framework CreateQuery method but after googling the issue I am now clearer.

I have two questions:

1) Is this the WRONG way to mock dependency injection of an ISession

2) Is there a way to modify the code so that it can successfully return my list

            [Test]
            public void DummyTest()
            {

                var mock = new Mock<ISession>();
                var loc = new Mock<User>();
                loc.SetupGet(x => x.ID).Returns(2);
                loc.SetupGet(x => x.FirstName).Returns("John");
                loc.SetupGet(x => x.LastName).Returns("Peterson");

                var lst = new List<User> {loc.Object};
                mock.Setup(framework => framework.CreateQuery("from User").List<User>()).Returns(lst);

                var controller = new UsersController(mock.Object);
                var result = controller.Index() as ViewResult;
               Assert.IsNotNull(result.ViewData);
            }

Please note, I am pretty sure I could just create a hard-coded list of users (rather than mocking an individual User and adding it to a list) but figured I'd leave the code as I have it right now.

Also, the Index action of this particular controller essentially executes the CreateQuery call mimicked above to return all users in the database. This is a contrived example - don't read anything into the details.

Thanks in advance for your help

Edit: In reply to the below comment, I am adding the stacktrace for the error. Also, all properties on the User class are virtual.

Below is the solution I came up with which seems to work perfectly. Again, I am not testing NHibernate and I am not testing the database - I simply want to test the controllers which depend on NHibernate. The issue with the initial solution appears to be the fact that I was calling a Method as well as reading the List member of the session in the MOQ setup call. I broke up these calls by breaking the solution into a QueryMock and a Session Mock (create query returns an IQuery object). A transaction mock was also necessary as it is a dependency (in my case) of the session...

        [Test]
        public void DummyTest()
        {
            var userList = new List<User>() { new User() { ID = 2, FirstName = "John", LastName = "Peterson" } };
            var sessionMock = new Mock<ISession>();
            var queryMock = new Mock<IQuery>();
            var transactionMock = new Mock<ITransaction>();

            sessionMock.SetupGet(x => x.Transaction).Returns(transactionMock.Object);
            sessionMock.Setup(session => session.CreateQuery("from User")).Returns(queryMock.Object);
            queryMock.Setup(x => x.List<User>()).Returns(userList);

            var controller = new UsersController(sessionMock.Object);
            var result = controller.Index() as ViewResult;
            Assert.IsNotNull(result.ViewData);
        }
