Worked on the grafana/k6 repository to deliver a new IntersectionRatio-based viewport visibility system for the browser module. Developed an injected-script helper using IntersectionObserver in JavaScript and Go, enabling accurate measurement of element visibility within complex layouts such as scrollable containers and elements with CSS transforms or clipping. Introduced the Locator.IsInViewport() API, which supports configurable ratio thresholds and timeout handling to align with Playwright semantics. Added comprehensive browser tests covering in-viewport, below-the-fold, and ratio-threshold scenarios. This work improved the reliability of UI test automation by reducing flakiness in visibility checks and enhancing the accuracy of in-viewport detection.
May 2026 monthly summary focused on feature delivery and reliability improvements in the grafana/k6 repository. Delivered an IntersectionRatio-based viewport visibility system to improve reliability of in-viewport checks in the browser module, including an injected-script helper and a new Locator.IsInViewport() API with configurable ratio and timeout. Added tests covering in-viewport, below-the-fold, and ratio-threshold scenarios. These changes align with Playwright semantics and reduce flaky UI tests by accurately detecting element visibility in complex layouts (scrollable containers, CSS transforms, clipping).
