VUG脚本录制——webtours案例：登录、订票、选择票、支付、查看、退出一系列事务，调试增强脚本。

涉及技术及知识点：

1）脚本常规设置之——订票正常循环5次、扩展日志查看、关闭日志查看ouput中打印提示、脚本乱码设置等；
2）脚本增强之——关联函数：登录、选择票务、支付判断订票是否成功，3处分别写关联函数，调试运行脚本，成功。（注意：动态值从response中获取确认无误）；
3）脚本增强之——参数化：订多张票时，设置每张票不同出发和到达城市，调试运行脚本，成功。（注意：选择系统自带的城市，否则关联不到城市，脚本回放不成功）；
4）脚本增强之——登录/退出只执行一次，设置，调试运行脚本，成功；
5）脚本增强之——关联函数中增加顺序选择，调试运行脚本，成功。（ord，票务顺序不对，未增加ord时所有票都是一张）；
6）脚本增强之——判断订票是否成功（if/else语句），打印订票成功、失败的提示语，调试回放脚本，成功；
7）脚本增强之——在init和end中打印提示语，便于在output中查看提示是否设置成功。

上述内容源码展示：
