我正在创建几个单元测试来测试我的应用程序逻辑。在下面，我创建了两个基于order是否为真的final变量。有没有一种方法可以让它变干，而不必为每一种order类型都创建final变量？

private static final Order FIRST_ORDER = createOrder(
     "watch",
      "123",
      true
  );

  private static final Order SECOND_ORDER  = createOrder(
     "watch",
      "123",
      false
  );

  private static Order createOrder(String productName, String productId, Boolean isNewOrder){
  //Logic
  }

  @Test
  public void shouldTestOrderCreation(){
      OrderHelper helper = new OrderHelper();
      helper.createOrder(FIRST_ORDER);
  }

  @Test
  public void shouldTestOrderCreation(){
      OrderHelper helper = new OrderHelper();
      helper.createOrder(SECOND_ORDER);
  }
