During the month, contributed to the backstage/community-plugins repository by modernizing the testing infrastructure for the Apollo Explorer workspace. Focused on migrating the test suite to Jest 30, this work improved compatibility with the latest JavaScript features and enhanced the reliability of continuous integration feedback. The migration included aligning Allure integration and updating type definitions to ensure cross-environment stability. By leveraging JavaScript, Node.js, and Jest, the changes reduced flaky tests and laid the foundation for faster, safer release cycles. No explicit bug fixes were reported, as the primary emphasis was on strengthening test coverage and supporting scalable plugin development.
