What is Load Testing?
Load testing measures how a system behaves under realistic and heavy traffic—many concurrent users, high request rates—to reveal performance bottlenecks, slow responses, and breaking points before real users hit them. It answers questions functional tests can't: how many users can we serve, where does latency spike, and what fails first under stress. Load testing is a form of non-functional testing and complements functional coverage; a feature can be perfectly correct yet still fall over under load, which is why both matter for a production-ready release.
