LR使用小技巧：
1、 问题：在用LR的Wdiff（VUGen->Tools->Compare
with Vuser…）进行脚本比对查找需要关联点时，出现了“file no longer available”的提示信息
解决方案：
因为脚本保存路径中的文件夹存在空格，所以将文件夹重命名后，重新开启lr脚本，进行比较就ok啦
2、 问题：使用LR路中socket脚本，如何实现关联，并且输出内容以进行检查
解决方案：
关联有两种，一种是自动关联，一种是手动关联。
关联主要参考的文档是data.ws，在data.ws中找到需要关联的地方，然后在Action中相应的buf后面进行关联，或者将脚本设置为Tree View模式，找到待关联的值，右键->Create
Parameter就可以创建一个关联了，然后系统会提示用户是否用参数替换所有的值，选【ok】以后，可以在参数列表中查看，哪些需要替换的，需要替换的就保留，不需要的undo就可以了。
关联用到的函数有三个：lrs_save_param、lrs_save_param_ex、lrs_save_searched_string
可以在脚本中使用lr_output_message函数输入需要的内容进行脚本的调试，也可以通过该函数自己设置检查点，检查脚本是否正确。
一般情况下在receive到的buffer部分做关联
3、 问题：在用Controller 进行场景设置以后，运行时出现了“You do not have a for this Vuser
type.Please contact Mercury Interactive to renew your license.”
解决方案：
原因是由于目前使用的License不支持Socket场景运行，将License替换一下就可以了。
使用的License也就是目前网络上比较通用的两个：
global 100user
AEAMAUIK-YAFEKEKJJKEEA-BCJGI
10000 web clients
AEABEXFR-YTIEKEKJJMFKEKEKWBRAUNQJU-KBYGB
一开始使用的10000 web clients的，出现该问题，后来替换成global 100 user 就可以了。具体视情况而定。
