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.

Performing a Load Test

Introduction

In the previous chapters, we learned how to create our load test scripts. It is now time to execute these scripts.

We will take this opportunity to bust some myths about JMeter not being suitable for "big load tests."

To do this, we will look at the different ways to perform a test and the best practices to follow in order to succeed.

Methodology

The method we recommend to execute your test campaign is the following:

  1. Create your scripts with the GUI.
  2. Maintain your scripts with the GUI.
  3. Run mini-tests with the GUI to validate your scripts, the datasets used, and the platform (both the injection platform and the target platform).
  4. Run the proper load test from the command line.
  5. If you need to test multiple (Internet Protocol) IP sources or go very high in terms of the number of virtual users, run the test in distributed mode or with a cloud injection platform.
