In April 2025, John Forbes focused on enhancing the stability of the compiled testing utilities in the atlassian-labs/compiled repository, specifically addressing issues with SVG element handling. He resolved a runtime crash in the toHaveCompiledCss matcher by replacing the use of element.className.split with element.classList, ensuring compatibility with SVG nodes. John also expanded the Jest-based test suite to include SVG-specific scenarios, increasing test coverage and regression protection. Working primarily with JavaScript and TypeScript, he delivered a robust fix that improved reliability for downstream consumers, reducing flaky test runs and contributing to more stable frontend development and testing workflows.
