Performance Testing with JMeter 3

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...

Configuring the JMeter HTTP(S) Test Script Recorder

The first step is to configure the proxy server in JMeter. To do this, we perform the following steps:

  1. Start JMeter.

 

  1. Add a thread group, as follows:
    1. Right-click on Test Plan and navigate to Add | Threads (User) |
      Thread Group.
    2. Right-click on Thread Group and navigate to Add | Logic Controller | Recording Controller.
  2. Add the HTTP(S) Test Script Recorder element, as follows:
    • Right-click on WorkBench and navigate to Add | Non-Test Elements | HTTP(S) Test Script Recorder.
  3. Change the port to 7000(1) (under Global Settings).
  4. You can use a different port if you choose to. What is important is to choose a port that is not currently used by an existing process on the machine. The default is 8888.
  5. Under the Test plan content section, choose the Test Plan>Thread Group (2)> Recording Controller option from the Target...

Setting up your browser to use the proxy server

There are several ways to set up the browser of your choice to use the proxy server. We'll go over two of the most common ways, starting with my personal favorite, which is a browser extension.

Using a browser extension

Google Chrome and Firefox have vibrant browser plugin ecosystems that allow you to extend the capabilities of your browser with each plugin that you choose. For setting up a proxy, I really like FoxyProxy (http://getfoxyproxy.org/). It is a neat add-on to the browser that allows you to set up various proxy settings and toggle between them on the fly, without having to mess around with setting systems on the machine. It really makes the work hassle-free. Thankfully...

Anatomy of a JMeter test

With the samples we have explored so far, we have seen a similar pattern emerging. We have seen what mostly constitutes a JMeter test plan. We'll use the remainder of this chapter to explore the anatomy and composition of the JMeter tests.

Test plan

This is the root element of the JMeter scripts and houses the other components, such as threads, config elements, timers, Preprocessors, Postprocessors, assertions, and listeners. It also offers a few configurations of its own.

First off, it allows you to define user variables (name-value pairs) that can be used in your scripts later. It also allows the configuration of how the thread groups that it contains should run, that is, should thread groups...

Summary

We have covered quite a lot in this chapter. You learned how to configure JMeter and our browsers to help record test plans. In addition, you learned about some built-in components that can help us feed data into our test plan and/or extract data from server responses. In addition, you learned what composes a JMeter test plan and got a good grasp on those components.

In the next chapter, we will dive deeper into form submission and explore more JMeter components.

負荷テストを行う際にどういった指標を用いるべきか、またどんなことに気をつけるべきかなどから始まり、Jmeterの使い方が学べます。他にもどういったテストツールが存在しているかなども書いてあり、個人的に好感が持てます。あくまでも個人の感想ですが、負荷テスト経験がない方やJmeterを初めて扱う方には、よくまとまった良書だと思います。既にJmeterを大規模に運用されている方には物足りないかもしれません。

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.
