Learn how to get the most out of JMeter, improve the productivity of your apps, and integrate JMeter with your Agile and DevOps processes. 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. This book contains all the valuable information you need in one place and is a must for everybody who is seriously working with JMeter. It might be a little condensed for absolute beginners, but this book is the best you can find if you already have some performance testing experience and want to get further. In particular, it would be invaluable to developers who want to expand their JMeter knowledge into advanced topics or switch to JMeter from other load testing tools.
I think it's as of october 2019, the best book about performance testing with JMeter and the most up to date. The interesting thing is that it is written by three developers of JMeter so you learn best-practices and tips that even as a senior user of it I didn't know about. For beginners (which I am not anymore :-) ), I find the learning path nicely introduced with a lot of real life examples, and I was happy to read about problems I have faced in my job to which some solutions are given. The DevOps part is also very interesting as it presents how to integrate JMeter in CI/CD, knowing one of the author is also contributor to JMeter Maven Plugin so they know what they write. Finally the performance testing process is nicely introduced which is missing in other books I have read on JMeter.
