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.

Methodology

As with all tests, testing an MOM and/or server should be as realistic as possible.

For example, if the messages exchanged are persistent, the same thing must be done with JMeter. Likewise, the same applies to the other parameters (such as delay, authentication, and so on).

Note

My advice is to speak with the developers and/or architects about allowing the test to be configured so that it is as representative of reality as possible.

Let's look at what we need to test.

JMeter can test the following (note that this is a non-exhaustive list):

  • The configuration of the MOM – for this, JMeter must play the roles of producer and consumer:

  • The performances of our consumer – here, we will only use JMeter as a producer:

  • The resilience of our MOM configuration – in this case, JMeter plays the roles of producer and consumer...
