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.

Putting It into Practice with JMeter

To simplify the examples, we will not implement all the good practices outlined in the Chapter 5, Prepare Test Environments (Injectors and Tested System) and Chapter 3, Design a Test Case.

In particular, note that the tests will be performed locally (on JMeter and MOM) – avoid this in real life!

Example 1: Testing the Configuration of an MOM server with Point-to-Point Messaging

Our first test will be on an MOM server with point-to-point messaging.

We will use ActiveMQ as our MOM:

  1. Before starting with our JMeter test plan, let's create a queue named JMeterBook.
  2. At first, we will send a message in a queue.
  3. In JMeter, we will configure JMS Point-to-Point as follows:
Figure 10.41: Sending a message in ActiveMQ

In this example, we generate a unique JMSCorrelationId identifier using the following JMeter functions:

  • ${__time(YMD,)}: Returns the current date
  • ${__threadNum}: Returns the number of the current thread
  • ...
