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.

Setup with JMeter

JMeter is a Java program, and as such, it accesses MOM through the JMS API.

Installing the MOM libraries

The first thing to do is to install the JMS client implementation of the MOM provider (usually a .jar file) in the JMETER_HOME/lib directory.

For example, for Apache ActiveMQ, take the activemq-all-X.X.X.jar file (where X.X.X depends on the version that you're using).

The JMS Point-to-Point Element

To simulate point-to-point communication, JMeter offers the JMS Point-to-Point element:

Let's look in more detail at some of the parameters.

JMS Resources and JNDI Properties

Let's start with the JMS Resources and JNDI Properties settings.

Java Naming and Directory Interface (JNDI) is a Java programming interface (API) for Java object naming inside the Java virtual machine; so, in short, it is a directory.

In the case of JMS, JNDI is used to retrieve the instances of the destination objects (Topic or Queue...
