Master Apache JMeter - From Load Testing to DevOps

By: Antonio Gomes Rodrigues, Bruno Demion (Milamber), Philippe Mouawad

Overview of this book

Load tests help identify the maximum number of requests a software system can handle. One popular open source tool for load testing is JMeter. By leveraging the features and capabilities of JMeter, you can perform extensive load testing and fix issues in your application before they become problematic. This book is written by JMeter developers and begins by discussing the whole process, including recording a script, setting it up, and launching it, enabling you to almost immediately start load testing. You'll learn the best practices that you must follow while designing test cases. You'll also explore the different protocols offered by JMeter through various real-world examples. Finally, you'll see how to integrate JMeter into the DevOps approach and create professional reports. You'll discover ways to use the eco-system of JMeter to integrate new protocols, enrich its monitoring, and leverage its power through the use of the cloud. By the end of this book, you'll know all that's needed to perform comprehensive load testing on your applications by using all the best practices and features of JMeter.

JMeter Overview

Apache JMeter is a software that allows you to perform load tests on various protocols and technologies.

It was developed by the Apache Software Foundation (

JMeter is an application written in Java and offers an integrated development environment (IDE) for load test development.

This IDE has multiple looks and feels (LAFs), the default one shown here is based on Darcula LAF. Later in this book, we'll use the cross-platform LAF for presentation purposes because it is white.

JMeter runs on any Java-compatible OS (including Linux, Microsoft Windows, macOS, and so on).

The application can also be used on the command line, in other words, without a graphical interface, which is the mode that should be used systematically during your load tests.

JMeter is multithreaded and can simulate a lot of virtual users (VUs).
