When running a protocol based load test with JMeter, it is always a challenge to make sure the server responses are correct. The default validation is only done on HTTP response codes based on their value: OK < 400 <= KO And since 4XX and 5XX HTTP response codes are error messages it makes sense.

You want each concurrent user to pick a different login password. It’s way more realistic to simulate concurrent users using unique logins and passwords because it’s closer to the real world load.

A complete guide on how to use JMeter’s While Controller to design loops that break on a specific condition.


JMeter’s While controller is best suited for advanced scripts which simulate realistic user behaviors. It allows to define a behavior which occurs on a certain condition. Designing realistic behaving users involves designing users whose behavior depends on the server responses, and act accordingly. This post explores in details various JMeter While usages and explains them thoroughly. Difference with If Controller The difference is pretty simple to understand: If controller children are executed zero or one time when the condition is met, While controller children are executed zero, one or multiples times depending how many times the condition is met.
