Load Testing Tools

by AlohaRubyConference.com on February 22, 2022

In order to maintain applications which are suitable for large number of requests, it is important to make that specific application undergo load testing.

Load testing helps in writing, running and defining the test scenarios. A test scenario can either be a web application or a script that can be used in the stimulation of a typical behavior of the user in multiple pages. Once the test scenario is defined, you can execute it and determine how your application works.

There are many load testing tools out there that can be used in building, conducting and analyzing the stress and load tests for different web applications and services. While using these tools, many of them requires you to create a test scenario beforehand and when the scenario is performed on the website or application it helps in the stimulation of many virtual users as well.

Some of the famous load testing tools is:
