I'm familiar with user defined variables in jmeter & have it setup to provide a random email address using;
When running this in a test of 100 threads however I'm seeing the exact same email address being used in post data which is causing errors.
I've got jmeter set to save cookies, but the cookie manager set to clear on each iteration.
So how do the user defined variables actually work? Does each get a value set per iteration? My thread group is setup for 100 threads, so I expected that to create 100 random email addresses based on the above definition of an email address.
