3 Must-have Chrome Extensions for Web Load Testing

Web Load Testing requires monitoring of a web application or a website as the load on it (the size and volume of requests) increases gradually. Load testing helps to measure the maximum operating capacity of a web application and find the problem areas that might limit the function of the application. In this post, we’ll exclusively talk about the top 3 Chrome extensions for web load testing that can help the test engineers eliminating a lot of manual efforts in their regular testing process.

What are the factors influencing the call for Web Load Testing?

Multiple reasons contribute to the need for load testing the Web applications. One of the principal goals of load testing is to determine the Web applications performance under both normal and peak load situations. As you start load testing, it is advisable that you begin with a small number of virtual users and then slowly increase the volume to achieve the desired result.

With this approach, you can easily track the application performance taking advantage of the window you get from gradually extending the load condition. Ultimately, you will reach a threshold limit for your performance milestones. For example, you may carry on building the load until the server CPU usage reaches 75 percent, or when the end-user response times breach the 8 seconds timeframe.

Load testing v/s stress testing?

Don’t synonymize Load testing with stress testing. The later determines the extent to which a system can continue to hold under extreme workloads or when some of its components (hardware or software) start to crumble. On the other hand, load testing defines the maximum amount of charge a system can handle without reporting any significant performance degradation.

What are the best practices to carry out load testing?

There are few thumb rules that you can keep in mind while designing the Web load testing scenarios.

  • Cover the primary sequence of actions that user would be doing.
  • Capture scenarios which may lead to high loads. For example, transactions that involve excessive database access.
  • Spend at least some of the time doing exploratory testing.

In the next section, we are listing the top 3 Chrome extensions that can optimize the load testing process of any web application. But before you dive into viewing the Chrome plugins, have a look at the following blog post on the Load Testing interview questions.

Let’s now check out the desired Chrome extensions.

1. BlazeMeter Chrome Extension for Load Testing.

BlazeMeter Chrome Extension for Web Load Testing.

This plugin has thousand of users who are using it for the web load testing purpose.

It can record all the HTTP requests and produce a load test in a very short time.

There are following two modes which it supports.

1.1. FollowMe.

It is an automatic mode which doesn’t require scripting the tests.

You would only need to browse the website and it’ll imitate a no. of virtual users swarming on your site for load testing.

1.2. Record.

It is partly a manual mode that captures all your browsing sequence and produces JMeter scripts.

The scripts then automatically offload to the BlazeMeter. Later, you can run or export them with a single click.

Feature summary.

  • Captures all HTTP/S traffic exchanged via your browser.
  • Its scripts are compatible with Apache JMeter.
  • It can test an application without even requiring a test script.
  • You can scale load tests for up to 1 million concurrent users.
  • You need to enroll for a BlazeMeter account (free).

2. The Load Impact User Scenario Recorder.

This extension also has a large community of users. It operates similarly as the BlazeMeter does in Record mode.

  • You first need to secure a free Load Impact account to start.
  • This extension keeps a track of all the HTTP(S) sessions that the browser initiates.
  • It records the sessions into scripts and instantly sends to your Load Impact account.
  • Once the scripts get to the Load Impact account, you can edit them using Lua, which is a modern high-level scripting language.
  • Load Impact’s service allows running up to 10 different users scenarios per load test. And you can simulate up to 1.2 million concurrent users.
  • It does support the multiple user scenarios to run from ten discrete geo locations in a single test.

Load Impact comes with a special Server Metrics Agent. It will report the following statistics.

  • CPU usage,
  • Memory usage,
  • Disk I/O,
  • Network I/O, and
  • Any other data shared by the 3000+ Nagios plug-ins.

3. The Load Focus Extension for Load Testing.

It’s a free cloud-based Website and API Load Testing extension.

  • You can easily use it for creating and inspecting results for your site.
  • Additionally, it allows running the API load tests and website speed tests.
  • It enables performing Load testing directly from the cloud, and it doesn’t require to write any code.
  • A free user account registration is mandatory to start using it.

Summary – Chrome Extensions for Web Load Testing.

This article provides to the point information on load testing and the best practices for its implementation. We wish that the software testers reading this post would immensely benefit from these plugins. All the three Chrome extensions for web load testing are extremely useful and easy to use.
