About this Episode:

Welcome back to the TestGuild performance and SRE podcast, I'm your host Joe, and today we're diving into the world of frontend performance testing. As we all know, the majority of end user response time is spent on the frontend, and yet, it's an area that is often overlooked in performance testing. That's why I'm thrilled to have Marie Cruz, a Developer Advocate at k6_io & grafana, on the show today to talk about xk6-browser, a tool that combines backend and frontend performance testing into one powerful package. This session was taken from my anual Automation Guild conference that took place this Feb. If you missed you can get instant access to all the sessions that took place at

Marie will take us through why frontend performance is just as important as backend performance, and why performance testing is about more than just load testing. She'll then introduce us to xk6-browser, an extension to k6 that adds browser-level scripting APIs to interact with real browsers and collect frontend metrics as part of your k6 tests. With xk6-browser, you'll be able to measure how your frontend is behaving during certain events which would be difficult to catch from the protocol-level.

So, whether you're a performance engineer or a developer looking to optimize your web application's user experience, this episode is for you. Listen up!
