Please help! Delegate returns null via Dipendency Injection.
- by Raj Aththanayake
Can someone please help?
I use Google code’s Moq framework for mocking within my Unit Tests and Unity for Dependency Injection.
In my Test class
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");
}
In my Test class CustomerService class
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
}
}
When I debug the code I can see CustomerSearchService has a proxy object, but the customer returns as null. Any ideas? Or is there something missing here?
Note: ICustomerSearchService I have implemented below method.
Customer GetCustomer(Func<Customer, bool> predicate);
