启用身份验证和授权的WCF服务类单元测试

Question

我有一个WCF服务，它启用了UserName身份验证和PrincipalPermission Authorization。

如何对该方法进行单元测试。

服务：

    [PrincipalPermission(SecurityAction.Demand, Role = "Admin")]
    public void UploadEmployees(CustomerRequest request)
    {
        try
        {
            ProcessEmployees(request.PacketId, request.Employees);
        }
        catch (Exception ex)
        {
            throw new FaultException<CustomerException>(new CustomerException { Status = -1, ErrorMessage = ex.Message });
        }
    }

My Nunit测试方法：

    [Test]
    public void CallProcessEmployee_Should_Work()
    {
        var service=new CustomerService();
        var request = new CustomerRequest();
        service.UploadEmployees(request);
    }

当我尝试执行单元测试时，我得到的错误是：

System.Security.SecurityException : Request for principal permission failed.

如何在启用了身份验证和授权的类上进行单元测试。？

我通过创建一个"setup"方法并将主体设置为当前线程来解决这个问题，如下所示：

    [SetUp]
    public void SetupUnitTestPrinciple()
    {
       var identity = new GenericIdentity("Unitest");
       System.Threading.Thread.CurrentPrincipal = new CustomPrincipal(identity);
    }
