Howdy techies! With our continuous efforts to empower the QA community, we are thrilled to announce the support for Grafana k6 Browser, an open-source tool for browser automation and end-to-end web testing, on the LambdaTest automation testing cloud.

Yes, you read that right! On LambdaTest, you can now accelerate web automation testing by leveraging immense k6 core capabilities to perform k6 browser testing at scale across different browsers and OS combinations.

Dive in to see what k6 browser testing on LambdaTest can do for you.

Overview of k6

Developed by Grafana Labs and its community, Grafana k6 is an open-source tool to perform load testing. It streamlines and helps engineering teams in their performance testing efforts. k6 is a flexible solution that is developer-focused, allowing you to test the reliability and efficiency of your software applications quickly.

Overview of k6

Besides enabling teams to identify performance bottlenecks and regression bugs at an earlier stage of the Software Development Life Cycle, k6 lets developers build scalable, high-performing websites and applications. k6 comes with several features, including:

  • An easy-to-use CLI tool with a developer-friendly API.
  • You can write JavaScript ES2015/ES6 scripts with support for local and remote modules.
  • The use of Checks and Thresholds can help you achieve goal-oriented, automated-friendly load testing.

Developers and testers mainly use k6 to test the performance and reliability of APIs, microservices, and websites. The following are some of the most common uses of k6:

  • Load testing
  • Browser testing
  • Chaos and resilience testing
  • Performance and synthetic monitoring

What is the k6 Browser Module?

With the k6 Browser Module, you can perform browser automation and end-to-end web testing via Chrome DevTools Protocol while leveraging the core k6 features. The k6 Browser module adds a slew of browser-level APIs to interact with browsers and collect metrics about front-end performance while running k6 tests.

k6 Browser Module supports Chromium-based browsers.

A browser module serves the purpose of running performance tests at the browser level. By performing tests at this level, you can evaluate the user experience and identify any issues that might be difficult to detect at the protocol level. Using browser testing to analyze different aspects of your website can provide you with valuable information that can answer questions such as:

  • How does the front end of an application behave when it receives a massive chunk of simultaneous requests at the protocol level?
  • What are the specific metrics related to browser performance, such as total page load time?
  • Are all the front-end elements functioning in an interactive manner as intended?
  • Are there any loading spinners that remain visible for an extended period?

How to scale your k6 Browser Testing with LambdaTest?

Even though k6 has a powerful feature set, the true potential of k6 testing can only be tapped by running tests on a scalable and reliable cloud grid. Are you planning to perform cross browser testing with k6 at scale by avoiding endless investments in setting up an in-house testing infrastructure?

LambdaTest offers a cloud-based digital experience testing platform that seamlessly integrates with k6, enabling you to perform web automation and end to end testing on an online browser farm of real browsers, operating systems, and devices. With LambdaTest, you can effortlessly run your k6 tests in parallel, saving cost and resources.
