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.

Preparation of the System under Test

The preparation of the system under test is just as important as that of the injectors.

A Testing Environment

To avoid wasting time finding bugs that are not related to performance, it is important to have a stable application that has been thoroughly tested.

If the load tests are written just before production deployment, there will be little time left for the tests.

This means that if the application has not been functionally and technically tested (for example, with unit and integration testing), every bug detected during the load tests will jeopardize the planned date for the start of production and under good conditions.

Load testing (even if it can be automated with continuous integration) should not be used to replace Non Regression testing.

An Environment Consistent with the Target

Ideally, you should have an environment that is equivalent to the production environment.
