Question

有人可以帮忙吗？

我使用Google代码的Moq框架在我的单元测试和Unity依赖注入中进行模拟。

在我的测试课程中

private Mock<ICustomerSearchService> CustomerSearchServiceMock = null;
private CustomerService customerService = null;

private void SetupMainData()
{
    CustomerSearchServiceMock = new Mock<ICustomerSearchService>();
    customerService = new CustomerService ();

    // CustomerSearchService is a property in CustomerService and dependency is  configuered via Unity
    customerService.CustomerSearchService = CustomerSearchServiceMock.Object;

     Customer c = new Customer ()
     {
         ID = "AT"
     };

     CustomerSearchServiceMock.Setup(s => s.GetCustomer(EqualsCondition)).Returns(c); 
}


[TestMethod]
public void GetCustomerData_Test_Method()
{
    SetupMainData()
    var customer = customerService.GetCustomerData("AT");
}


 public static bool EqualsCondition(Customer customer)
 {
     return customer.ID.Equals("AT");
 }

CustomerService类

public class CustomerService : ICustomerService
{

    [Dependency]
    public ICustomerSearchService CustomerSearchService { get; set; }


    public IEnumerable<SomeObject> GetCustomerData(string custID)
    {

      I GET Null for customer ?????}
      var customer = CustomerSearchService.GetCustomer (c => c.ID.Equals(custID));

       //Do more things
    }
}

当我调试代码时，我可以看到CustomerSearchService有一个代理对象，但客户返回null。有任何想法吗？或者这里缺少什么？

注意：ICustomerSearchService我已经实现了以下方法。

     Customer GetCustomer(Func<Customer, bool> predicate);

我在Rhino.Mocks中也看到了这个问题（模拟，lambdas和存根/期望）。参见：

请帮忙！委托通过依赖注入返回null
