Understanding Performance Testing

Defining Performance Testing

Performance testing is a non-functional software testing method that evaluates the speed, scalability, and reliability of a system under a certain workload. Its primary purpose is to ensure that the software application will perform well under their expected workload scenarios. Performance testing encompasses a variety of tests that include load testing, which checks the application’s behavior under normal and peak load conditions, and stress testing, which determines the app's robustness by testing beyond normal operational capacity, often to a breaking point in order to identify the system's failover point. By defining the key metrics such as response time, throughput, and resource utilization standards, performance testing can help uncover what needs to be improved before the product goes to market.

It’s crucial to clarify the purpose and scope of performance testing before starting, as it sets the foundation for the testing process. A comprehensive performance testing strategy will differentiate between various types of testing needed for the product, including but not limited to endurance testing, scalability testing, and volume testing. Understanding the differences and applications of each type of performance testing is vital for effective analysis and optimization.
