Hi,
the application i'm testing makes heavy use of jsp in combination with JavaScript to
carry user session information. I did not find a test-tool that could handle it, but
jmeter can. Great!
However, i found no other solution than using __regexp. This works fine for one Thread
in a Thread Group, but as soon as i want to put some load on the system and increase
the number of threads (simulating multiple parallel users), the second set of user
session variables overwrites the first one because regular expressions are global.
Being a newbie to jmeter, i think i can
1. Run multiple jmeter instances with each of them having one Thread. As i'm planning
for about 100 parallel users, this results in 100 JVMs.
2. Make the ID of the current thread part of the session variable , e.g.
__regexp(,,,,,, window_context_${__threadNum}). Not very manageable.
3. Modify the jmeter source to make regular expressions ThreadLocal. Same result as
with __counter : First argument TRUE if you wish each simulated user's counter to be
kept independent and separate from the other users.
Can anyone image drawbacks if all regular expressions were looked up thread local
first?
