Developed a reusable authentication module test utility for the upstars-global/front-platform-core repository, focusing on improving test coverage and reducing duplication in authentication flows. The work involved introducing and exporting a new test function within the authentication entity, designed as a placeholder utility to standardize test scaffolding across the application. Implemented entirely in TypeScript and leveraging front-end development best practices, the solution consolidated test logic into a single, maintainable module. This approach enabled consistent and efficient testing for authentication features, streamlining the process for future development and ensuring that authentication-related code could be more easily validated and maintained over time.
