Performance testing is a type of software testing that evaluates how a system or application performs under different conditions and workloads. It aims to identify bottlenecks, measure response times, and assess system behavior in scenarios that mimic real-world usage. Performance testing includes various subtypes, such as load testing, stress testing, and scalability testing.
For example, an e-commerce website may undergo performance testing to determine how it handles a high volume of simultaneous users during a sale event. Testers simulate heavy user traffic to ensure that the website maintains responsiveness and stability under such conditions.
