Stress testing, also known as load testing or endurance testing, is a type of software testing that aims to evaluate the performance and stability of a system or application under heavy loads and conditions of stress. The purpose of stress testing is to determine how a system behaves when it is pushed beyond its normal operational limits, and to identify any performance bottlenecks or stability issues.
Stress testing is necessary in a number of scenarios, including:
- High-traffic systems: For systems that are expected to handle a large number of simultaneous users, stress testing can be used to validate that the system can handle the expected load.
- Mission-critical systems: For systems that are critical to the operation of an organization, stress testing can be used to ensure that the system can handle unexpected spikes in usage and maintain its stability and reliability.
- Systems with non-functional requirements: For systems that have specific non-functional requirements, such as response time, throughput, or availability, stress testing can be used to validate that these requirements are met under heavy loads and stress conditions.
Overall, stress testing is an important aspect of software testing, as it can help identify performance and stability issues before they become critical problems in production.
