Performance Testing

Performance testing is a type of non-functional software testing that is used to evaluate the performance of a software application or system under a specific workload. The goal of performance testing is to determine how the system performs in terms of responsiveness, reliability, and resource usage under normal and peak load conditions.

Performance testing is typically performed to ensure that the system can handle the expected number of users or transactions, and to verify that it remains stable and responsive under heavy load. It is also used to identify any performance bottlenecks or issues that may occur, and to determine the scalability of the system.

There are several different types of performance testing, including:

• Load testing, which involves evaluating the performance of the system under a specific load.
• Stress testing, which involves evaluating the performance of the system under extreme load conditions to determine the breaking point of the system.
• Scalability testing, which involves evaluating the ability of the system to handle an increasing workload.

Performance testing is usually performed by developers or testers who are responsible for evaluating the performance of the system. It is an important part of the software development process, as it helps to ensure that the system will be able to handle the expected usage in a production environment.
