How to let jMeter http request sampler generate parameters?

Question

Is there a way to generate random parameter values in jMeter http request sampler or any other sampler?

Answer 1

In JMeter, you can use counters to generate parameter values. Add your counter to the top of your test plan and choose initial, increment and maximum values. It will start counting automatically.

counter is in Pre Processors menu. You can use the counter values in HTTP samplers by using reference name. i.e. let's say your reference name is ref_counter then you can call its values in HTTP samplers with ${ref_counter}.

Answer 2

You can try to use some of jmeter's functions to generate random value:

• __Random to generate random int: ${__Random(MIN, MAX};
• __RandomString to generate random string: ${__RandomString(LENGTH)};

as well as Random Variable config element for the same purpose.
