Performance Testing

Performance testing is a software testing methodology that evaluates how a system performs under specific workloads, focusing on responsiveness, stability, scalability, and resource usage. It involves simulating real-world user traffic to identify bottlenecks, measure throughput, and ensure the system meets performance requirements before deployment.

Also known as: Load Testing, Stress Testing, Perf Testing, Performance Engineering, Scalability Testing

Why learn Performance Testing?

Developers should learn performance testing to build scalable and reliable applications, especially for high-traffic systems like e-commerce platforms, financial services, or real-time applications. It helps prevent downtime, optimize resource allocation, and meet service-level agreements (SLAs) by identifying issues like slow response times or memory leaks early in development.
