Stressztesztelési

Stressztesztelési, or stress testing, is a software testing methodology used to determine the stability and responsiveness of a system under extreme conditions. It involves subjecting a system to workloads that are significantly higher than its expected normal operational load. The primary goal of stress testing is to identify breaking points, detect performance bottlenecks, and assess how the system recovers from failures or overload.

This type of testing is crucial for understanding the application's behavior when resources are scarce, such as limited memory, processing power, or network bandwidth. By simulating high traffic, concurrent user access, or large data volumes, developers can uncover issues that might not appear during standard functional or performance testing. Common metrics observed during stress tests include response times, throughput, error rates, and resource utilization.

Stress testing helps in preventing system crashes, data corruption, and unexpected downtime. It provides insights into the system's resilience and its ability to maintain acceptable performance even under duress. The results of stress tests inform decisions about system architecture, resource allocation, and capacity planning, ensuring a more robust and reliable end product for users. It is often conducted as part of a comprehensive performance testing strategy.
