Worked on the LifeSG/web-frontend-engine repository to enhance the reliability of the unit testing process. Addressed a test infrastructure issue by updating the test runner configuration, replacing focused tests with standard test execution to ensure all tests run by default. This adjustment eliminated the risk of hidden focused tests passing unnoticed in both local and CI environments, thereby improving test suite robustness. The work was limited to the testing framework and did not affect production code. Utilized JavaScript and TypeScript, applying frontend development and unit testing skills to deliver a targeted bug fix that strengthened overall code quality assurance practices.
