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.

Load Testing Web Services

A Few Concepts

Nowadays, more and more applications use web services ( for several reasons:

  • To adapt to new constraints
  • To interface mobile applications
  • To interface heterogeneous systems in distributed environments
  • To provide services to partners
  • To avoid tying interfaces to a particular library in a specific language, and so on

This service is frequently used, particularly with the success of microservice architectures ( Under the term "web services," several technologies exist, such as WS-\* web services and REST web services. Let's look in more detail at these two technologies.

REST (REpresentational State Transfer) Web Services

To meet certain needs (such as a lower complexity of implementation, reducing the volume of data exchanged and reducing the parsing cost, particularly for mobile applications, and more), REST...
