Question

Say I have a method A.Do(Arg arg) which assigns some properties of arg (class Arg), let’s say it sets arg.Prop1 = "done". And I’m testing a void method B.Do(void):

public class B
{
  public void Do()
  {
    var arg = InitArg();
    A.Do(arg)
    ...
  }
}

and I’ve mocked class A as new Mock< A>() with CodeBase=true. So how do I verify that arg.Prop1 == "done"?

Answer 1

With the example as given, you can’t. arg is private to the method B.Do(), so it’s not visible to the outside world, so you can’t verify any of its properties.
