CSV Data Set Config/JSESSIONID Question
Hello,
I have a question about the CSV Data Set Config - I'm not sure if what I'm
seeing is a bug or intended.
I am trying to stress test a webapp that serves out thousands of domains.
So I'm trying to use a CSV Data Set to read in all the domains and user
agents that I've seen in production. I use those as variables for the other
elements.
Here's what I have:
-Test Plan
- Thread Group
- HTTP Cookie Manager
- CSV Data Set Config
- Filename: /path/to/my/file.txt
- Variable Names: host,ua
- HTTP Request
- Server name or IP: ${host}
- Path: /mypath
- Browser-derived Headers
- Host: ${host}
- User-Agent: ${ua}
This is working just fine, except for one thing. Every time a thread goes
through a Thread Group iteration, JSESSIONID is reset. "Clear cookies on
each iteration?" is *not* checked in the HTTP Cookie Manager element.
Now, if I disable the CSV Data Set Config and set the host and ua variables
in a User Defined Variable element at the top, the sessions are not cleared
on each iteration (which is what I want). It looks to me like the CSV Data
Set Config element is resetting each thread's cookie map on each iteration.
Is that something I should expect or is it a bug?
Also, is there a better way to vary the domain? I have tens of thousands of
domains that I need to cycle through, so hand entering them isn't feasible.
I could write something that generates a bunch of Thread Groups based on the
domain, but that seems like a pain (tens of thousands of Thread Groups seems
ugly).
Thanks,
Chris

The CSV data set does not interact with the Cookie Manager, so I don't
see how this is possible. Can you e-mail me the JMX file privately?

I would normally suggest using CSV data set for this.
However, as an alternative, you could use the StringFromFile and split
functions to achieve much the same.

OK, thanks for confirming that it is not a JMeter problem.

Hello again,
So I don't think this has anything to do with the CSV Data Set Config and
don't think it's an issue at all.
A good chunk of my domains are actually sub-domains, which cause Tomcat to
issue a new JSESSIONID and a new session. I had assumed that meant that my
old session was gone and that was bad. However, my other cookies are indeed
intact across the JSESSION changes.
All is well.
Thanks for the help!
Cheers,
topher
