Question

I have been battling with writing some unit test for some of our code and I am struggling with this one:

We have a method that we overloaded and it is like this:

 Public Client GetClient(int productID)
 {
  //Some sql that evaluate a client

  if(!GetClient(clientRef,ClientTypeRef))
   Return Client.UnknownClient;
    //some other sql and codes
  Return Client.CustomerClient;
  }

The problem is how do I approach this, in my test I tried to add a mock to the GetClient(clientRef,ClientTypeRef) and returning an OK Client (anything other than Client.UnknownClient) to allow me to continue but I am getting a null reference? Is it possible to mock and test such methods, and how would I continue with this.

Answer 1

What mocking frame work are you using?

I use moq, to mock this method you would do something like

 _mockClientRepository.Setup(x => x.GetClient(It.IsAny<int>(),It.IsAny<int>())).Returns(Client.CustomerClient);

Basically this means that any integer passed to the method will always return Client.CustomerClient
