Testing / Apache JMeter Interview questions
What are Timers in JMeter?
Timers introduce a delay between requests, simulating the pauses ("think time") a real user takes between actions instead of a virtual user firing requests back-to-back as fast as possible.
Common types include the Constant Timer (a fixed delay), the Uniform Random Timer (a random delay within a range, on top of an optional fixed offset), and the Gaussian Random Timer (a delay following a bell-curve distribution around a target value), each producing a different, more or less realistic pacing pattern.
Without timers, a load test can generate unrealistically aggressive traffic that doesn't reflect how real users actually interact with the system, potentially producing misleading performance results.
Timers are used to:
