Worked on enhancing test coverage for modal components in the learningequality/kolibri repository, focusing on SelectDriveModal and SelectTransferSourceModal. Migrated existing tests to the Vue Testing Library, which improved both accuracy and maintainability of the test suite. Expanded coverage by adding missing tests and strengthening assertions to help prevent modal regressions. Refined test data handling and removed redundant code, streamlining the overall testing process. Emphasized front end development and testing best practices using JavaScript and Vue.js, with additional improvements to code style and pre-commit linting. These efforts contributed to more reliable CI workflows and easier onboarding for future contributors.
