A lot of companies—even if they are aware that performance is key to their business—are often unsure of how, when, or where performance testing sits within their development lifecycle. To make things worse, they’re also usually unsure whose responsibility performance measuring and monitoring is.

Automating quality gates is ideal, as it minimizes manually checking and validating key metrics throughout the SDLC. By actively monitoring metrics such as error rate, success rate, and CPU load, quality gates instill confidence in teams during software releases. Several tools can be used to collect metrics in load/performance testing.

To ensure that users get high-performing software that works seamlessly under all load conditions, performance testing is necessary. This test helps to measure the speed, scalability, reliability, and stability of software under varying loads, thus it ensures stable performance. What Is Performance Testing?
