Performance testing is a type of software testing that assesses an application’s overall performance, stability, speed, scalability, and responsiveness under certain circumstances. Performance testing’s main objective is to confirm that the system or software operates effectively and satisfies predetermined performance standards, particularly under anticipated or unforeseen loads.There are various Performance Testing Tools and applications that are especially designed to enable performance test planning, carrying out, managing, monitoring, reporting, and analysis for websites, apps, and software systems.

What is the role of Performance Testing Tool:

There are three major capabilities of a Performance Testing Tool:

• Simulate load conditions of the System Under Test (SUT)
• Monitor system behavior
• Analyze performance metrics to make recommendations
