JMeter：如何在多个线程组循环中重用/重新打开CSV？

Question

在JMeter中，我有一个用户的CSV列表，每个用户都应该上传一定数量的文件。这些文件列在第二个CSV中。每个用户必须上载所有文件。由于服务器不能同时处理所有线程，我将线程组设置为使用X个用户并循环Y次，这样最终所有用户都上传所有文件。

 Test plan
 - CSV Data Set Config (contains users) --> Recycle = false, Stop thread on EOF = false
 - Thread Group (X users, Y loops)
 - - While Controller ( ${__javaScript("${uploadFile}"!="<EOF>")} )
 - - - CSV Data Set Config (contains files) --> Recycle = false, Stop thread on EOF = false
 - - - HTTP Request (upload file)

作为一个示例，使用3个线程/用户和2个循环的结果如下所示：

**first loop**
user 1
  upload file 1
  upload file 2
  upload file 3
user 2
  upload file 1
  upload file 2
  upload file 3
user 3
  upload file 1
  upload file 2
  upload file 3
**second loop**
user 4
user 5
user 6

来自第二个循环的用户也应该遍历files-CSV并上传文件。知道我做错了什么吗？提前谢谢！！

我认为您需要在EOF上启用回收。我还会检查jmeter的日志，以获取关于jmeter为什么不再发送任何请求的某种提示。

从jmeter文档中,

When the end of file (EOF) is reached, and the recycle option is true, 
reading starts again with the first line of the file.

If the recycle option is false, and stopThread is false, then all the 
variables are set to <EOF> when the end of file is reached. This value 
can be changed by setting the JMeter property csvdataset.eofstring .
