The Grafana k6 browser module simulates how users interact with a browser page and collects web performance metrics about the interaction. Since launching the module in 2021, we're frequently asked how it compares to Google Lighthouse as a tool to measure web page performance. This blog post compares k6 browser and Google Lighthouse from various perspectives.

Grafana k6 v0.44.0 has been released, featuring new experimental modules, an upgraded browser module, and tons of improvements. Here's a quick overview of the latest k6 news from the team and the community.
There are many aspects of application performance, but they broadly fall into two categories: frontend performance and backend performance. As a tester, it’s important to know the differences between the two and how that impacts the way you approach your tests. In this blog, I’ll provide a high-level overview of frontend performance testing and backend performance testing, including pros and cons of each one.

Modern applications are built on a microservices architecture that leverages cloud-native technologies. This architecture has many benefits regarding scalability and fault-tolerance of individual components, but it also increases the complexity of the applications, mostly due to the interdependencies between services. This complexity makes it difficult for engineers to fully understand how their applications will react to abnormal conditions, such as a dependency failure or performance degradation.

Organizations use load and performance testing to prevent issues from impacting customers, which is essential if they want to stay relevant in today’s digital-first world. And with the rise of cloud native technology and DevOps, software teams must shift performance testing left, towards development. However, traditional load and performance testing tools simply haven’t kept pace, leaving developers, operations, and QA teams siloed.

Load testing, which is as a type of non-functional testing that puts a structure or system under pressure and measures its response, might sound boring. In reality the entire process of planning, estimating, and implementing load tests against the system is like putting together pieces of a complex puzzle, and it can be a lot of fun.

As of k6 version 0.43.0, xk6-browser is now bundled in k6 as an experimental module! 🙌 Since announcing xk6-browser in November 2021 at Grafana ObservabilityCON, the team have been busy adding on new features to include browser automation in k6. The interest from the community has also increased, which shows that browser automation and frontend performance is as important as backend performance.

In this article, we will discover the process of sending custom metrics, provided to us through the xk6-browser, in order to gain a better understanding of our performance tests. Through the integration of these metrics, we will be able to create more tailored Slack messages that will help to manage our rule sets.

Grafana Faro and xk6-browser are both new tools within the Grafana Labs open source ecosystem, but the pairing is already showing a lot of potential in terms of frontend monitoring and performance testing. Faro, which was announced last November, includes a highly configurable SDK that instruments web apps to capture observability signals that can then be correlated with backend and infrastructure data.

k6 is a developer-centric, free and open-source load testing tool built for making performance testing a productive and enjoyable experience. Using k6, you'll be able to catch performance regression and problems earlier, allowing you to build resilient systems and robust applications.
Quickly build test cases to validate the performance of your APIs or microservices. Validate that your system can handle the expected volume of traffic, and catch SLA/SLO-breaking performance regressions in CI before they reach production.
Built primarily for load testing, k6 tests can with advantage be reused for performance monitoring of your APIs and microservices in production.
Features:
- Seamless scaling to the cloud: Designed to use the same test in a local, distributed or cloud environment. It provides an unified experience for various usage.
- Built for automation: Designed for automating your performance tests. Get Pass/Fail behavior on your performance goals.
- Write tests in Javascript code: Full scripting language to write realistic load tests. Reuse modules and Javascript libraries to build and maintain your test suite.
- Multiple choices for storage: k6 can output test results to various backends and formats (Grafana, DataDog, Kafka, JSON).
- Easy-to-use APIs and CLI: Designed for developers by developers. The k6 API and CLI is intuitive, flexible and powerful.
- High-performance tool: The k6 engine is written in Go making to be one of the best performing load testing tools.
The best developer experience for load testing.
