性能测试学习第八天_脚本编写
设置关联
打开测试服务器，在http://localhost:1080/WebTours/页面点击administration，勾选set login form‘s action tag to an error page。用于分配动态session id
之后录制登录退出的脚本，进行验证回放，发现回放失败了
提示需要设置关联，所以我们在脚本关联结果中，进行录制快照中的文本与回放快照中的文本进行关联，如下图
关联之后的脚本如下
Action() { //Correlation comment - Do not change!Original value='36533009' Name ='CorrelationParameter_1' web_reg_save_param_ex( "ParamName=CorrelationParameter_1", "LB=118546.0", "RB=z", SEARCH_FILTERS, "Scope=Body", "RequestUrl=*/nav.pl*", LAST); //Correlation comment - Do not change!Original value='VVpHftVzzzH' Name ='CorrelationParameter_2' web_reg_save_param_ex( "ParamName=CorrelationParameter_2", "LB=H", "RB=D", SEARCH_FILTERS, "Scope=Body", "RequestUrl=*/nav.pl*", LAST); //Correlation comment - Do not change!Original value='Afcf' Name ='CorrelationParameter_3' web_reg_save_param_ex( "ParamName=CorrelationParameter_3", "LB=H", "RB=>\n<table border", SEARCH_FILTERS, "Scope=Body", "RequestUrl=*/nav.pl*", LAST); web_url("WebTours", "URL=http://localhost:1080/WebTours/", "Resource=0", "RecContentType=text/html", "Referer=", "Snapshot=t2.inf", "Mode=HTML", LAST); lr_think_time(9); web_submit_data("login.pl", "Action=http://localhost:1080/WebTours/login.pl", "Method=POST", "RecContentType=text/html", "Referer=http://localhost:1080/WebTours/nav.pl?in=home", "Snapshot=t3.inf", "Mode=HTML", ITEMDATA, "Name=userSession", "Value=118546.0{CorrelationParameter_1}zAQHH{CorrelationParameter_2}DzfizpcH{CorrelationParameter_3}", ENDITEM, "Name=username", "Value=jojo", ENDITEM, "Name=password", "Value=bean", ENDITEM, "Name=JSFormSubmit", "Value=on", ENDITEM, "Name=login.x", "Value=46", ENDITEM, "Name=login.y", "Value=14", ENDITEM, LAST); web_image("SignOff Button", "Alt=SignOff Button", "Snapshot=t4.inf", LAST); return 0; }
html录制模式和url录制模式
1.html模式录制的脚本

添加事务（Transaction）
事务定义：事务是一个点，我们为了衡量某个操作的性能，在操作的开始和结束位置插入这样一个范围，即定义了一个transaction
添加事务原因：从性能测试角度出发，要知道不同操作所花费的时间，就用到了事务，我们在操作之前插入一个事务开始标识，在操作完成后插入一个事务结束标识，这样我们就知道这个操作所花费的时间。
事物的作用：LR运行到该事务开始点时开始计时，直到运行到该事务的结束点，计时结束。这个事务的运行时间会在LR的运行结果中反映。即，事务是一个计时标志。通常事务时间所反映的是一个操作过程的响应时间。
事务的函数构造：添加事务可以 插入-开始事务（Ctrl+T）/结束事务(Ctrl+D)，或者点击
lr_start_transaction("login"); web_url("WebTours", "URL=http://localhost:1080/WebTours/", "Resource=0", "RecContentType=text/html", "Referer=", "Snapshot=t2.inf", "Mode=HTML", LAST); lr_end_transaction("login", LR_AUTO);
其中LR_AUTO：自动返回检测到的状态
运行结果：
Action.c(6): 在 HTML“http://localhost:1080/WebTours/nav.pl?in=home”中找到资源“http://localhost:1080/WebTours/images/mer_login.gif” [MsgId: MMSG-26659] Action.c(6): web_url("WebTours") 已成功，6449 个正文字节，1608 个标头字节 [MsgId: MMSG-26386] Action.c(15): 通知: 事务 "login" 以 "Pass" 状态结束 (持续时间: 7.1189 浪费的时间: 3.3532)。 Action.c(19): 将表单提交到“http://localhost:1080/WebTours/login.pl”，目标帧=“body” [MsgId: MMSG-27978]
Duration表示事务的完成响应时间，wasted time包括事务中函数自身执行所消耗的时间
参数化设置
参数化详解可以参考，写的很详细http://www.cnblogs.com/fnng/archive/2012/06/22/2558900.html
http://www.cnblogs.com/candle806/archive/2011/07/18/2109607.html
1.参数化之间的关联
主要用于用户名和密码的对应，如果，我们已经对用户名进行了参数化username，如果让用户名和密码进行对应，则需要设置密码参数和用户名关联
之后选择123456右键选择替换为参数，参数名称为passwd，选择右下角属性
从文件路径下，选择刚刚创建的username.dat，然后添加列，点击用记事本编辑，输入对应的密码，保存后页面如下
关闭后，点击完成，即完成了用户名和密码的参数化与对应
脚本设置完参数化，脚本运行的每一遍所取的参数化的值都不一样，那么这个值按照个什么情况来取呢？会有很多种方式
Select next row【选择下一行】:
顺序（Sequential）：按照参数化的数据顺序，一个一个的来取。
随机（Random）：参数化中的数据，每次随机的从中抽取数据。
唯一（Unique）：为每个虚拟用户分配一条唯一的数据
Update value on【更新时的值】：
每次迭代(Each iteration) ：每次迭代时取新的值，假如50个用户都取第一条数据，称为一次迭代；完了50个用户都取第二条数据，后面以此类推。
每次出现(Each occurrence)：每次参数时取新的值，这里强调前后两次取值不能相同。
只取一次(once) ：参数化中的数据，一条数据只能被抽取一次。（如果数据轮次完，脚本还在运行将会报错）
内容检查
勾选运行时设置下首选项中的 启用图像和文本检查
录制完脚本后 任务->内容检查，会显示脚本快照，选择一个要检查的页面，右键点击添加文本检查
如图可以看出添加检查点的函数为web_reg_find
确定后，脚本中添加了如下内容
web_reg_find("Search=Body", "Text=Find Flight", LAST);
日志解析
1.回放日志
2.录制日志
3.生成日志
错误处理函数
运行时设置（F4）
VuGen提供了错误处理函数void lr_continue_on_error(int value);
value是脚本运行时出错设置的取值，具体取值及相应含义如下表：
在使用表中参数时，常量名和常量值都可以作为参数
| 常量名称 | 常量值 | 含义 |
| LR_ON_ERROR_NO_OPTIONS | 0 | 取消出错继续执行设置 |
| LR_ON_ERROR_CONTINUE | 1 | 发生错误继续运行脚本 |
| LR_ON_ERROR_SKIP_TO_NEXT_ACTION | 2 | 发生错误跳至下个Action运行 |
| LR_ON_ERROR_SKIP_TO_NEXT_ITERATION | 3 | 发生错误跳至下个迭代运行 |
| LR_ON_ERROR_END_VUSER | 4 | 发生错误结束当前用户 |
常用的是0和1，通常成对使用，适合压力较大且在夜间自动运行的测试场景，这类场景通常会在运行时设置中开启出现错误时仍继续选项
关键业务发生错误时需停止执行，通过lr_continue_on_error(0)实现
非关键业务发生错误时无需停止运行，通过lr_continue_on_error(1)实现
移动APP脚本录制
安装一个LR11 Patch4补丁，为了协议中有mobile app这个协议
之后，电脑和手机一个网段
