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.

Types of Load Tests Supported

JMeter is a generic test tool that has great flexibility and adaptability to meet multiple scenario requirements.

Specifically, here are some examples of possible load tests:

  • Check the response times of a web application, according to the number of virtual users
  • Test differences in the behavior of the same application on two (or more) different runtime environments (for example, clustered environment versus non-clustered environment, or configuration 1 versus configuration 2)
  • Test the limits of an application (the number of users the application can accommodate before it crashes)
  • Functionally test an application automatically (with non-regression tests, functional validity tests, and so on), often coupled with a continuous integration tool
  • Reproduce a load-related production bug in a QA environment
  • Automate load testing in the continuous integration (CI) process
  • Test a database, a lightweight directory access protocol (LDAP) (or Active...
