针对RCW设计测试？

Question

好的，我做错了什么或者根本没做什么，这里？

待测方法：

    public iManageWorkspace(ManDMSClass manDms, string server, string database, string userId, string password)
    {
        if (manDms == null) throw new ArgumentNullException("manDms");
        if (server == null) throw new ArgumentNullException("server");
        if (database == null) throw new ArgumentNullException("database");
        if (userId == null) throw new ArgumentNullException("userId");
        if (password == null) throw new ArgumentNullException("password");
        this.manDms = manDms;
        this.server = server;
        this.database = database;
        this.userId = userId;
        this.password = password;

        manProfileSearchParameters = manDms.CreateProfileSearchParameters();
        manWorkspaceSearchParameters = manDms.CreateWorkspaceSearchParameters();
        dbList = GetDbList(this.database);
    }

    public void Login()
    {
        manSession = manDms.Sessions.Add(server);
        if (manSession == null)
            throw new ApplicationException("Failed to start DMS session");

        manSession.Timeout = timeout;
        manSession.Login(userId, password);
    }

测试代码：

    [Test]
    [ExpectedException(typeof(ApplicationException))]
    public void GetWorkspaceList_CreateWithNoAbilityToCreateSession_ThrowsApplicationExceptionOnLogin()
    {
        var mockProfileParams = new Mock<IManProfileSearchParameters>();
        var mockWorkspaceParams = new Mock<IManWorkspaceSearchParameters>();

        var mockDmsClass = new Mock<ManDMSClass>();
        mockDmsClass.Setup(manDms => manDms.CreateProfileSearchParameters()).Returns(mockProfileParams.Object);
        mockDmsClass.Setup(manDms => manDms.CreateWorkspaceSearchParameters()).Returns(mockWorkspaceParams.Object);
        mockDmsClass.Setup(manDms => manDms.Sessions.Add("serverName")).Returns<IManSession>(null);
        var manageWorkspace = new iManageWorkspace(mockDmsClass.Object, "serverName", "database", "userId", "password");

        //// Assert
        Assert.Throws<ApplicationException>(manageWorkspace.Login);
    }

例外：
