如何在Jmeter中提取响应字符串的出现次数，如果出现的次数与数字不匹配则不通过测试？

Question

我正在尝试计算Jmeter中响应的出现次数，如果计数不等于4，则测试应该失败。

我该怎么做？

我在beanshell断言中使用了这个：

Import org.apache.commons.lang3.StringUtils;

int matches = StringUtils.countMatches(new String(data), "itemname"); 
vars.put("ItemNameVar_matchNr", String.valueOf(matches));
assert matches == 5;

它。不管用。它显示错误：

  

类型变量声明：未定义的参数：data

1. 您在Beanshell断言中没有sqlite> select s61.station, ...> (select count()+1 from (select station,avg(dayobs.ave_temp)/10 as t61,sum(dayobs.rain)/10 as r61 from dayobs where month=5 and year>=2015 and days>=1 and days<=15 group by station,year) as r where r.t61 > s61.t61 and s61.station==r.station) as rantk_t ...> from (select station,avg(dayobs.ave_temp)/10 as t61,sum(dayobs.rain)/10 as r61 from dayobs where month=5 and year>=2015 and days>=1 and days<=15 group by station,year) as s61; Error: misuse of aggregate: avg() ，有一个预定义的变量select s61.station,s61.year, (select count()+1 from tt as r group by year having r.t61 > s61.t61 and s61.station==r.station) as rantk_t from (select station,year,avg(dayobs.ave_temp)/10 as t61,sum(dayobs.rain)/10 as r61 from dayobs where month=5 and year>=2015 and days>=1 and days<=15 group by station,year) as s61; ，它是字节数组。

2. 您在Beanshell中没有data，您有ResponseData预先定义的布尔值，表示范围内的采样器是否应该成功。

3. 完整代码：

   assert
