测试脚本和开发一样，并不是一蹴而就的，通常要经过代码评审、编码、和测试等流程后，才会趋于稳定。VU脚本也需要调试、修改才能使得它更加完美。另外请注意解决测试脚本不仅要求你有过硬的技术，还要明确测试流程。

1.那么脚本编写的最佳流程应该是怎样的？请看：

最佳流程实践

（1）Generate：录制或开发脚本

（2）SUSI（Single  User Single Iteration，单用户单循环）：运行录制生成的脚本，解决可能存在的关联问题。

（3）SUMI（Single  User Multi Iterations，单用户多循环）：参数化脚本，在Run-Time Settings中设置Iteration，再次运行，验证参数化问题。

（4）MUSI（Multi  User Single Iterations，多用户单循环）：Controller里多用户运行脚本，验证脚本中可能的多线程同步问题。

（5）MUMI（Multi  User Multi Iteration，多用户多循环）：即性能测试的开始。

其中我们可以明确看出，第（1）、（2）、（3）是在Vuser中完成的，（4）、（5）是在Controller中完成的。

2.按照最佳流程实践做以下实例：

使用VU录制web Tours（机票预订网站），完成一个完整的机票预订流程，包括登陆、选择预订条件、下订单。具体要求如下：

（1）按照最佳实践流程的（1）、（2）、（3）来完成脚本。

录制的原脚本如下：

}

（2）按照关联实践，查看是否有需要关联的数据。

对于关联这里：因为我单用户单循环，单用户多循环都没有报错，所以没有进行关联。

所以只对订票日期和座位位置坐了参数化。

（3）能够在Controller中实现5个用户并发，选择不同的条件预订机票，考虑VU参数表应该怎样设计，怎样修改脚本，并通过设置迭代次数来验证参数表机制。

这部分后续学习了补上~~~嘿哈
