We know that we'll need to instantiate Ship for every spec, so we might as well refactor the specification class by adding the @BeforeMethod annotation. The code can be the following:

@Test
public class ShipSpec {

  private Ship ship;
  private Location location;
 
  @BeforeMethod
  public void beforeTest() {
    Location location = new Location(new Point(21, 13), Direction.NORTH);
    ship = new Ship(location);
  } 

  public void whenInstantiatedThenLocationIsSet() { 
    // Location location = new Location(new Point(21, 13), Direction.NORTH); 
    // Ship ship = new Ship(location); 
    assertEquals(ship.getLocation(), location); 
    } 
} 

No new behavior has been introduced. We just moved part of the code to the @BeforeMethod annotation in order to avoid duplication, which would be produced by the rest of the specifications that we are about to write. Now, every time a test is run, the ship object will be instantiated with location as the argument.
