What is Performance Testing?

Student Assignment

Performance Testing

Published on Oct 12, 2022

It is a non-functional testing technique performed to determine the system parameters in terms of responsiveness and stability under various workload. The goal of performance testing is not to find bugs but to eliminate performance bottlenecks.

Why do we need performance Testing?

  • It determines whether the application responds quickly.
  • It determines the maximum user load the software application can handle.
  • It determines if the application is stable under varying loads.

Advantages of Performance Testing

  • Validate Features
  • Measure speed, accuracy & Stability
  • Keeps user happy
  • Improved Optimisation
  • Identify Discrepancies

Types of Performance Testing

Load Testing
Checks the applications ability to perform under anticipated user loads. The objective is to identify performance bottlenecks before the software application goes live.

Endurance Testing
This is done to make sure that the software can handle the expected load over a long period of time.

Volume Testing
The large number of data is populated in a database and the overall software systems behaviour is monitored. The objective is to find software applications performance under varying database volumes.

Scalability Testing
The objective of the scalability testing is to determine the software applications effectiveness in scaling up to support an increase in user load.

Spike Testing
This tests the software’s reaction to sudden large spikes in load generated by the users.

Stress testing
This tests the software application under extreme workloads to see how it handles high traffic or data processing the objective is to identify the breaking point of the application.
