c# – 如何在WCF ServiceAuthorizationManager中模拟IContextCha

我正在尝试为自定义ServiceAuthorizationManager编写单元测试.对CheckAccessCore的调用将OperationContext作为参数.要实例化OperationContext,必须将IContextChannel传递给构造函数.使用MOQ,我已经声明了一个IContextChannel：

private OperationContext _context;
private Mock<IContextChannel> _contextChannelMock;

然后我尝试创建OperationContext：

_context = new OperationContext(_contextChannelMock.Object);

但是这一行引发了一个例外：

Result Message: Initialization method
Urs.EnterpriseServices.Providers.Tests.UrsServiceAuthorizationManager_Tests.SetUp
threw exception. System.InvalidOperationException:
System.InvalidOperationException: Invalid IContextChannel passed to
OperationContext. Must be either a server dispatching channel or a
client proxy channel..

我如何模拟服务器调度通道？
