what is perfomance testing?

Question

1.load testing
2.stress testing
3.storage testing
4.data volume testing

Answer 1

Performance Testing is testing conducted to evaluate the compliance of a system or component with specified performance requirements.



Load testing is a blanket term that is used in many different ways across the professional software testing community.



Stress Testing : Testing conducted to evaluate a system or component at or beyond the limits of its specified requirements.



Storage Testing : Testing that verifies the program under test stores data files in the correct directories and that it reserves sufficient space to prevent unexpected termination resulting from lack of space. This is external storage as opposed to internal storage

Answer 2

Performance testing is a method of investigating quality related characteristics of an application.

or

Performance testing is the process of determining the speed or effectiveness of a computer, network, software program or device under certain conditions.

or

Performance testing, a non-functional testing technique performed to determine the system parameters in terms of responsiveness and stability under various workload.

Answer 3

Performance Testing is a continuous evolutionary process that helps in evaluating, defining, benchmarking, monitoring and managing performance and reliability of systems. Testing that provide greater insight into application performance and its overall architecture.



Collect Data by viewing application from multiple perspectives to address a broad array of problems, improve the performance of applications, and take action to prevent future problems.

Answer 4

Performance testing is the engine that drives the business in any organisation. It enables the customers, partners and employees to perform many diverse and business-critical transactions.



Performance testing is a testing process in which the testing is performed to determine how fast some aspect of a system performs under a particular workload.It is also used to check whether system meets performance criteria or not.

It is used to compare the two systems to find which performs better.It can also measure what part of the system or workload causes the system to perform badly.

The attributes like scalability, reliability and resource usage can be ,measured,validated and investigated by Performance testing
