Specification refactoring

To utilize a newly created TicTacToe constructor, we can do something such as the following:

private TicTacToeCollection collection; 
 
@Before 
public final void before() throws UnknownHostException {
  collection = mock(TicTacToeCollection.class);
// ticTacToe = new TicTacToe();
  ticTacToe = new TicTacToe(collection);
} 

Now all our specifications will use a mocked version of the TicTacToeCollection. There are other ways to inject mocked dependencies (for example, with Spring); however, when possible, we feel that simplicity trumps complicated frameworks.
