What is Performance Testing ?
Performance testing is an essential step in the software development life cycle that helps ensure the quality of a product or system. The purpose of performance testing is to measure how well a software application or system can perform under a given workload or stress. It allows developers and testers to identify and address potential performance issues before the product is released to end-users. Performance testing can help determine the responsiveness, speed, stability, scalability, and resource usage of the application or system. By testing the performance of software, developers can improve the user experience, optimize resource utilization, and ensure that the application or system can handle the expected load. In short, performance testing is critical for ensuring the quality, reliability, and usability of software applications and systems.
Quality is free, but only to those who are willing to pay heavily for it.
