Performance Testing

Performance Testing is a type of software testing that assesses a system's speed, responsiveness, stability, and scalability under a specific workload. The main goal is to identify and address bottlenecks or areas of degradation to ensure the application can handle expected user traffic without slowing down or crashing.

Example: A popular news website is launching a new live blog feature. To perform Performance Testing, the QA team simulates 10,000 users accessing the blog simultaneously. They then measure the system's response time, CPU usage, and memory consumption to ensure the page loads quickly and remains stable, even during a high-traffic event. This helps them confirm that the infrastructure can support a large number of concurrent users.
