In February 2026, Simon developed a Web Testing Dependencies Catalog for the apache/echarts repository, focusing on stabilizing test file access and improving the reliability of web component validation. He introduced a centralized JSON catalog to track WebKit dependencies, including HTML elements, WebGL contexts, and SVG elements, which automated the validation process and reduced flaky tests. Leveraging his skills in front end development, testing, and web development, Simon addressed a critical issue with test file access and enhanced the maintainability of the testing framework. This work provided a robust foundation for diagnosing WebKit-related test failures and streamlined onboarding for future contributors.
