软件测试第四周

闰年测试

  • 仍在之前的等价类测试 testApp 上进行功能上的修改
  • 将正则表达式改为 [0-9]{1-4},不足之处在于非数字和负数都归为了同一类「非法输入」,有待改进
  • buttomPress 方法下先使用正则表达式判断函数判断输入是否合法,如果符合要求再进行下一步计算验证
  • 先算是否为世纪年(模 100),若是则模 400 判断是否闰年
  • 非世纪年则模 4 判断是否闰年,最后由 UIAlertView 显示判断结果弹窗

测试用例

编号 输入 输出
1 2000 2000 是闰年
2 1900 1900 不是闰年
3 eadhwij 非法输入
4 -100 非法输入
