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.

Best Practices

Now that we know how to run a test, we will discuss some best practices to get the most out of JMeter.

These best practices come from:

Have Well-Prepared Injectors

As we have seen in Chapter 5, Preparing the Test Environment (Injectors and Tested Systems), it is important to prepare and calibrate our injectors.

Generating Reports at the End of the Test

The generation of reports during a load test can be very expensive and can introduce problems.

It is therefore strongly recommended to generate them only at the end of a test.

To monitor your test, the best solution is to set up the Backend Listener element to give real-time feedback on the test through third-party components such as Grafana and InfluxDB.

Remove all other listeners from your script before running the load test.
