Why Conduct Performance Testing?

Performance testing is a collection of manual and automated testing techniques to evaluate a software application’s speed, responsiveness, and stability when subjected to a particular load or volume of use. It helps to identify problems and bottlenecks before a release.


Delivering a world-class digital experience requires a consistently performant application across various end-user traffic patterns, network access locations, and device configurations.


The most functional and elegant user journey is only as good as the ability of the system to keep pace with factors that undermine performance. After all, a slow or unreliable user experience is a bad user experience.

A site that loads in 1 second has a transaction conversion rate 2.5x higher than a site that loads in 5 seconds. –

Types of Performance Testing

Imagine skilled testers supporting your automated and manual testing needs – scoping, scripting, test plans, test run management, and analysis.

  • Stress Testing: Push application beyond normal load conditions to determine which components fail first
  • Load Testing: Evaluate performance under increasingly high numbers of users
  • Volume Testing: Also known as flood testing, evaluate the application’s ability to handle large volumes of data
  • Scalability Testing: Determine the application’s ability to handle increasing load and processing
  • Spike Testing: Evaluate the application’s ability to handle sudden volume increases
  • Endurance Testing: Evaluate system performance under load over time
  • Network Conditions Testing: Leverage various simulated and real-world network condition tools to throttle and measure app performance
  • System-Level Testing: Validate performance of the front-end and back-end of the application
