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.

In this chapter, we have seen the following main features of MOMs:

  • Asynchronicity
  • Decoupling
  • Back pressure
  • Point-to-point communication
  • The publish/subscribe communication model
  • Broadcast
  • Priority of messages
  • Persistence of messages
  • JMS Selector
  • Durable Subscribers

We have tested these features in our JMeter scripts using Apache ActiveMQ and Apache ActiveMQ Artemis.

Then, we saw how to take advantage of the management features of MOMs using JMeter (specifically, the JSR223 Sampler element and a REST API).

When the core JMS elements of JMeter are not sufficient, it is still possible to do our tests using the integration between JMeter and Groovy via a JSR223 Sampler element.

Once again, you can see the endless possibilities that JMeter offers.
