The Performance testing is performed to know how fast the system is responding to a particular action. It is also called as non functional Testing. Performance testing is the way toward deciding the rate or viability of a PC, system, programming project or gadget. This procedure can include quantitative tests performed in a laboratory, for example, measuring the quantity of MIPS or the reaction time at which the framework capacities.

There are four different types of Testing. Each testing will perform different operation, such as:

If the application is running with huge amount of data is known as Volume Testing. If the developed application is running with minimum speed then it is known as Load Testing. If the developed application is running with minimum speed  such a period of time is called Soak Testing. Stress testing is a process of running the developed application to know the maximum speed of application is known as  Stress testing.

There are four different tools to test the performance of testing. They are

Load Runner

 Load runner measure the load and then check the performance of a system .

Jmeter

Jmeter is utilized to test the performance on dynamic and static resources.

Web load

Web load is utilized to test the performance on Scripting languages.

Open STA

Open STA is utilized to test test performance based on structure and content of a test case.

• To deliver a quality software product to the customer.
• The focus of performance testing is on responsiveness and scalability.
