What is Load Testing?

This post introduces you to an important type of testing in the field of software testing and it is called as Load Testing. We will start by understanding what is this testing all about and what role it plays in the business environment. Load Testing tests the performance/load of your software, hardware, servers, websites, apps etc according to the expected requirements. It is also called as “Endurance Testing” or “Longevity Testing”.

Load Testing is a type of non functional testing that monitors the working performance of the applications. In simple words, in software testing, it is a process of testing the applications for its response for applied varied load pressure. It is conducted to check the response level of the software/system at its normal and peak level. When Load testing is conducted above its peak level, it is named as stress testing.

Some of the examples of load testing:

  • Downloading large number of files
  • Running multiple tabs in a browser
  • Running multiple application on a computer system
  • Deleting a large number of files from a computer
  • Inserting large number of entries into database
  • Testing an online shopping site with a huge number of users shopping at the same time

Goal of Load Testing:

The goal of load testing is to determine the working behavior of the software application on various load pressure. It lets you enhance your software performance resulting in better software quality.


  • Leads to customer satisfaction
  • Reduces cost pressure
  • Minimizes performance gaps in software
  • Improves software quality
  • Improves software scalability and increases software reliability


  • Need expertise to execute
  • Automated testing tools cost heavily
  • Can’t be performed manually for large software application

Wrapping Up

Load Testing is a useful way to determine a system’s behavior under normal and anticipated peak load conditions. It is one of the most commonly conducted types of performance testing and can also be done to compare the capabilities of different systems.
