LR检查点用法小结

[font="Times]LR[/font]中检查点有两种：图片和文字。这两种检查点可用以下三个函数实现：[font="Times]web_find()[/font]、[font="Times]web_reg_find()[/font]和[font="Times]web_image_check()[/font]
下面分别介绍三种函数的用法
[size=5][font="Times]1.web_find()[/font][/size]函数
函数作用：在页面中查找相应的内容
参数举例：[font="Times]web_find("web_find","RighOf=a","LeftOf=b","What=name",LAST);[/font]
参数解释：[font="Times]"web_find"[/font]定义该查找函数的名称；“[font="Times]LeftOf[/font]”和“[font="Times]RighOf=[/font]”用来定义查找字符的左右边界；“[font="Times]What=[/font]”定义查找内容。
例如上述参数举例中的意思就是在页面中查找左边界为[font="Times]b[/font]，右边界为[font="Times]a[/font]，内容为[font="Times]name[/font]的信息
函数用法：该函数是在查找页面中的内容，所以要放在要查找的内容的后面。
[b]注意事项：使用该函数时，要在Vuser->Run-Tme Settings中勾选Enable Image and text check[/b][b]
[color=#000000][size=2]系统默认是不勾选该选项的。[/size][/color]
关于该函数的[url=javascript.:;][u][b]其他[/b][/u][/url]说明：该函数只能在基于HTML模式录制的脚本中进行查找。
[size=5][color=#000000]1.web_reg_find()函数[/size][/color]
[color=#000000][size=2]函数作用：在缓存中查找相应的内容[/size][/color]
[size=2][color=#000000]参数举例：web_reg_find("Search=Body","SaveCount=ddd","Test=aaa",LAST);[/size][/color]
[size=2][color=#000000]参数解释：Search用来定义查找范围，SaveCount定义查找计数变量名称，该参数可以记录在缓存中查找内容出现的次数，可以使用该值，来判断要查找的内容是否被找到[/size][/color]
[size=2][color=#000000]例如上述参数举例中的意思就是Body中查找内容为aaa的信息，并将出现次数记录在变量ddd中。[/size][/color]
[color=#000000][size=2]函数用法：该函数是在缓存中查找相应的内容，所以要放在查找内容之前。[/size][/color]
注：在录制过程中添加的检查点，用到的函数是web_reg_find()，且参数只有“Text=”
[size=5][color=#000000]2.web_image_check()函数[/size][/color]
[color=#000000][size=2]函数作用：在页面中查找一个具体的图片。[/size][/color]
[size=2][color=#000000]参数说明：web_image_check("web_image_check","Alt=","Src=",LAST);;[/size][/color]
[size=2][color=#000000]参数解释：“Alt”和“Src”的值直接取该图片在网页[url=javascript:;][u][b]源代码[/b][/u][/url]中相应参数的值。[/size][/color]
[color=#000000][size=2]函数用法：该函数是在缓存中查找相应的内容，所以要放在查找内容之前。[/size][/color]
注意事项：使用该函数时，要在Vuser->Run-Tme Settings中勾选Enable Image and text check，具体操作请看web_find()中的注意事项。
经过[url=javascript.:;][u][b][u][b]测试[/b][/u][/url][/b][/u]，该函数用到查找内容前面或后面，都不影响查找结果。
[color=#000000][size=5]举例说明（脚本）[/size][/color]
[size=2][color=#000000]该脚本记录的是登陆系统后退出的操作，在脚本中用到atoi()函数和lr_eval_string(”{SaveCount定义的变量}”)两个函数结合使用，判断查找内容出现的次数是否大于0，若大于0，则输入登录成功的信息。[/size][/color]

[color=#000000][size=5]1.[/size][/color]    [size=5]web_find()[/size][size=5]和[/size][size=5]web_image_check()[/size][size=5]函数的[url=javascript.:;][u][b]日志[/b][/u][/url]信息[/size]
[color=#000000][size=2]（这两个日志信息是上一样的，只是输出的函数名和参数不同）[/size][/color]
1）   信息1
[color=#000000][size=2]Action.c(22): Verification checks not enabled. web_image_check is skipped. See the 'Run-time settings/Preferences/Checks'        [MsgId: MMSG-27197][/size][/color]
[color=#000000][size=2]Action.c(22): web_image_check was successful      [MsgId: MMSG-26392][/size][/color]
出现该信息，说明没有勾选Enable Image and text check
2）   信息2
[color=#000000][size=2]Action.c(22): "web_image_check" succeeded (1 occurrence(s) found. Alt="", Src="/xjcost/jsp/images/index1/edit_01.gif")          [MsgId: MMSG-27192][/size][/color]
[color=#000000][size=2]Action.c(22): web_image_check was successful     [MsgId: MMSG-26392][/size][/color]
出现该信息，说明检查点设置成功，且已经查找到信息
3）   信息3
[color=#000000][size=2]Action.c(22): Error -27191: "web_image_check" failed (0 occurrence(s) found. Alt="", Src="/xjcost/jsp/images/index1/edit_1.gif")      [MsgId: MERR-27191][/size][/color]
[color=#000000][size=2]Action.c(22): web_image_check highest severity level was "ERROR"        [MsgId: MMSG-26391][/size][/color]
出现该信息，说明要查找的内容没有找到。这时依次尝试以下操作：
1）检查参数的信息是否写错；
2）如果是web_find(),检查函数的位置是否在要查找内容的后面；
3）如果是web_image_check()，查看该图片的源代码，看其是否是这个页面上的图片，很可能是图片选择错误，即所选图片不属于该页面。

[color=#000000]该信息在replay log页面是红色显示的，说明没有找到内容，出现此情况尝试以下两个操作：[/color]

[color=#000000][b]2）[/b][b]查看该函数是否在查找内容的前面[/b][/color][/b]
