Worked on the keycloak/keycloak repository to enhance the reliability and maintainability of its test suite by standardizing command-line interface usage in automated tests. Refactored test cases to consistently utilize the KcAdmMain.CMD entry point, which improved the clarity of error messages and reduced test flakiness in continuous integration environments. This approach centralized CLI invocations, making failures more visible and actionable for future debugging. The work demonstrated proficiency in Java, CLI development, and testing practices, with careful attention to code quality and collaborative workflows. These changes contributed to a more stable test infrastructure and streamlined future maintenance for the project.
