Chapter 2. Recording Your First Test

JMeter comes with a built-in proxy server (http://en.wikipedia.org/wiki/Proxy_server) to aid you record test plans. The proxy server, 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; that is, a JMX file. JMeter gives you the option of creating test plans manually, but this is mostly impractical for recording most 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 proxy server within JMeter.

  2. Setting the proxy in the browser.
