What is a load tester?

A Load Tester is responsible for evaluating a system's performance by simulating real-world user activity to identify potential bottlenecks, slowdowns, or failures. They design and execute load tests using tools like JMeter, LoadRunner, or Gatling to measure system stability under varying loads. By analyzing test results, Load Testers help ensure that applications can handle expected traffic and scale efficiently. Their role is crucial in preventing performance issues before deployment, ensuring a smooth user experience.
