Overview of this book

Table of Contents (14 chapters)


Performance testing is a type of testing intended to determine the responsiveness, reliability, throughput, interoperability, and scalability of a system and/or application under a given workload. It is critical and essential to the success of any software product launch and its maintenance. It also plays an integral part in scaling an application out to support a wider user base.

Apache JMeter is a free open source, cross-platform, performance testing tool that has been around since the late 90s. It is mature, robust, portable, and highly extensible. It has a large user base and offers lots of plugins to aid testing.

This is a practical hands-on book that focuses on how to leverage Apache JMeter to meet your testing needs. It starts with a quick introduction on performance testing, but quickly moves into engaging topics, including recording test scripts, monitoring system resources, an extensive look at several JMeter components, leveraging the cloud for testing, extending Apache JMeter capabilities via plugins, and so on. Along the way, you will do some scripting, learn and use tools such as Vagrant, Apache Tomcat, and be armed with all the knowledge you need to take on your next testing engagement.

Whether you are a developer or tester, this book is sure to give you some valuable knowledge to aid you in attaining success in your future testing endeavors.
