Performance testing ensures that a software system performs well under expected workloads over time by testing aspects like response time, speed, scalability, and stability. It is done to identify bottlenecks and limitations so they can be addressed before public release. There are different types of performance testing like load testing, stress testing, endurance testing and volume testing that evaluate how an application handles different types and levels of usage. The performance testing process involves planning tests, setting up environments, executing tests, verifying results, and retesting as needed.

1. We will take a look at the concept called performance
testing. As the name suggests, it deals with the overall
performance of the system under question, with regards to
the functionality. To learn performance testing tools, join a
course in Pune.
A Look At Performance Testing

2. What do you mean by performance testing?
Software testing is a method for quality assurance (QA).
It includes testing of software applications to guarantee
they will perform well under their normal workload.
Functionality and features bolstered by a software
system is not by any means the only concern. A product
application’s execution like its reaction time, do make a
difference. The objective of performance testing is not to
discover bugs but rather to dispense with execution
bottlenecks.

3. Stability: Checks if the system is stable under various
kinds of loads.
Speed: Checks whether the system responds fast in
terms of response time.
Scalability: Denotes the maximum amount of user load
the system can handle
The main focus of carrying out performance
testing is:

4. Performance testing is done to furnish stakeholders with data
about their application in regards to speed, scalability and
adaptability. All the more significantly, performance testing
reveals what should be enhanced before the product is
released. Without performance testing, a software is prone to
experience the ill effects of issues, for example, running slowly
while a few clients use it at the same time, irregularities
crosswise over various operating systems and poor usability.
Why to carry out performance testing?

5. Performance testing is divided into the following types:
Endurance testing- is carried out to ensure the product can deal
with the normal burden over a drawn out stretch of time.
Load testing- checks the application’s capacity to perform under
expected user loads. The goal is to distinguish performance
bottlenecks before the software application goes live.
Stress testing- includes testing an application under amazing
workloads to perceive how it handles heavy traffic or data
processing .The goal is to recognize limit of an application.

Volume testing- Under Volume Testing extensive no. of.
data is populated in database and the general software
systems conduct is checked. The goal is to check software
application’s execution under changing database volumes.
Scalability testing- The target of scalability testing is to
decide the product application’s adequacy in “scaling up” to
bolster an expansion in user load. It arranges limit
expansion to your software system
Spike testing- tests the product’s response to sudden huge
spikes in the load created by users.
