The application's performance is determined by its throughput, responsiveness, reliability, and scalability in the face of a given workload. This evaluation evaluates the software against its performance criteria. 

Performance testing is used to find bottlenecks within software applications and help identify compliance with initial requirements. Performance testing can also help to determine the requirements for hardware configurations during deployment. For more information about performance testing tools, you can visit this site.

Types of testing:

These four types of performance testing are possible to classify:

Performance

This validates the software's responsiveness, speed, stability, and scalability. This test measures the software's response time, throughput, and level of resource use. This category includes all performance-related testing.

Load testing

This test validates the software application's performance under normal and peak load conditions. This test identifies the application's breaking point under peak load conditions. Load testing can also include endurance tests. 

Stress

This is an extension to Load Testing. This test verifies the system's performance under conditions that exceed the expected workloads in production. It also checks the system for other stress conditions, such as insufficient disk space, limited memory, and server failure. 

Automated performance test tool

JMeter, an open-source Java testing tool that automates load and stress testing for application software, is available in Java. It can test both the static and dynamic performance of an application. It simulates heavy loads on servers or groups of servers in order to determine overall performance under various load types. 

For assessing business risks, Performance Testing is a vital activity. It identifies business risks and provides information about the usability, functionality, security, and reliability of the system.
