Performance testing is a critical priority and an essential part of testing software. It helps companies avoid long load times or even crashes that lead to the unfortunate loss of users. With the increasing interactivity of applications and requests to them from users, the load on the server is growing and requires a high level of service. Performance testing has become one of the most important testing stages, allowing the emulation of user queries for comparison with performance indicators that affect the application’s stability and tolerance.
Various types of performance testing help to evaluate the behavior of the application for a given expected load and assess the behavior of the system when the standard load is exceeded. In this guide, we discuss the nature of performance testing, what it is, why it’s important, when to apply it, and the various types of performance tests.
