Performance Testing

Performance Testing is a software testing process used for testing the speed, response time, stability, reliability, scalability and resource usage of a software application under particular workload.

The main purpose of performance testing is to identify and eliminate the performance bottlenecks in the software application. It is a subset of performance engineering and also known as “Perf Testing”.

The focus of Performance Testing is checking a software program’s

Speed — Determines whether the application responds quickly

Scalability — Determines maximum user load the software application can handle.

Stability — Determines if the application is stable under varying loads

The last decade has seen an overwhelming evolution of the Software Testing industry giving way to greener pastures.

It is important to ensure effective performance of software application and Software Testing is required to ensure that the application runs without any failures. This article on overview of JMeter and its features.
