In the realm of software development and testing, end-to-end (E2E) testing plays a pivotal role in ensuring the robustness and reliability of web applications. Unlike unit or integration testing, which focuses on specific components or integrations between them, end-to-end testing evaluates the entire system as a whole. This includes testing the flow from the user's perspective, from start to finish, and often involves multiple systems and components working in unison.

To maximize the performance and value of your software apps, networks and systems, it’s critical to eliminate performance bottlenecks. Performance testing has become critical in every organization to reveal and fix performance bottlenecks, ensuring the best experience to end users. This article explains what performance testing is, its importance, and the various types of performance testing.
