Rhinomock non-primitive object in expectations

Question

it seems comments can't support code

Lets say I call a method (e.g. SaveTicket) and have used constructor(e.g. Repository, Logging) to inject various mock interfaces. If that method calls another object and creates a non-primitive object inside that method. Is there any easy way to test the values of that non-primitive object?

I guess trying to replace that non-primitive object with property and injecting is possible, or Using LastCall.Constraints. Is there a better way?

Here is an example - in the below example - in order to verify Repository.save(t);

is called with correct values of t I can

1. Do lastcall.constraints

2. lastcall.ignorearguments

Is there a better way?

CreateMyTicket(int ticketnumber, string name)
{
   ticketobject t = new ticketObject(ticketnumber, name);
   t.upgrade = ticketnumber+2;
   Repository.save(t);
}

Answer 1

Let's take an example. Suppose that you have the following class and you want to unit test the CreateMyTicket method:

public class ClassToTest
{
    public IRepository Repository { get; private set; }

    public ClassToTest(IRepository repository)
    {
        Repository = repository;
    }

    public void CreateMyTicket(int ticketnumber, string name)
    {
        var t = new TicketObject(ticketnumber, name);
        t.Upgrade = ticketnumber + 2;
        Repository.Save(t);
    }
}

This assumes that we have an IRepository interface:

public interface IRepository
{
    void Save(TicketObject t);
}

and here's how a sample unit test could look like:

[TestMethod]
public void CreateMyTicketTest() 
{
    // arrange
    var repositoryStub = MockRepository.GenerateStub<IRepository>();
    var sut = new ClassToTest(repositoryStub);
    var ticketNumber = 5;
    var name = "John";

    // act
    sut.CreateMyTicket(ticketNumber, name);

    // assert
    repositoryStub.AssertWasCalled(
        x => x.Save(
            Arg<TicketObject>.Matches(t => 
                t.Upgrade == 7 && 
                t.Name == name && 
                t.TicketNumber == ticketNumber
            )
        )
    );
}
