Open Source Performance Testing Tools


Performance testing of software is required to measure the performance - response time, scalability, correctness of the application at expected or higher work load. In this post, we will be presenting top 5 open source performance testing tools along their advantages and limitations.

1. JMeter-

JMeter
  • JMeter is one of the most popular performance testing tools in the market. It's flexibility and online community support makes it an automatic choice over many of the paid tools also.
  • It can be used for performane testing of all kinds of applications ranging from - Web applications, web services, database, LDAP, shell scripts etc.
  • Beginners may feel a little difficult to understand it at first but once they get hold of this tool, it is very powerful and flexible. For JMeter tutorials refer to our automation turial section on JMeter.
  • JMeter also distributed load testing feature wherein one can create master-slave setup for carrying out load test on multiple devices.
  • Scripting is minimal in JMeter, it provides record and play option along with drag and drop feature. But it requires knowledge of regular expressions, web architecture, session variables, cookies etc. for creating JMeter scripts.
