Performance Testing with JMeter 3 - Third Edition

By: Bayo Erinle

Overview of this book

JMeter is a Java application designed to load and test performance for web application. JMeter extends to improve the functioning of various other static and dynamic resources. This book is a great starting point to learn about JMeter. It covers the new features introduced with JMeter 3 and enables you to dive deep into the new techniques needed for measuring your website performance. The book starts with the basics of performance testing and guides you through recording your first test scenario, before diving deeper into JMeter. You will also learn how to configure JMeter and browsers to help record test plans. Moving on, you will learn how to capture form submission in JMeter, dive into managing sessions with JMeter and see how to leverage some of the components provided by JMeter to handle web application HTTP sessions. You will also learn how JMeter can help monitor tests in real-time. Further, you will go in depth into distributed testing and see how to leverage the capabilities of JMeter to accomplish this. You will get acquainted with some tips and best practices with regard to performance testing. By the end of the book, you will have learned how to take full advantage of the real power behind Apache JMeter.

Chapter 2. Recording Your First Test

JMeter comes with a built-in test script recorder, also referred to as a proxy server (http://en.wikipedia.org/wiki/Proxy_server), to aid you in recording test plans. The test script recorder, once configured, watches your actions as you perform operations on a website, creates test sample objects for them, and eventually stores them in your test plan, which is a JMX file. In addition, JMeter gives you the option to create test plans manually, but this is mostly impractical for recording nontrivial testing scenarios. You will save a whole lot of time using the proxy recorder, as you will see in a bit.

So, without further ado, let's record our first test! For this, we will record the browsing of JMeter's own official website as a user would normally do. For the proxy server to be able to watch your actions, it will need to be configured. This entails two steps:

  1. Setting up the HTTP(S) Test Script Recorder within JMeter.
  2. Setting the browser to use the proxy...
