Worked on the bettercodepaul/swt2-bsa-backend repository to enhance the quality and maintainability of the test suite by standardizing constant naming within the SchuetzenstatistikLetzteJahreDOTest class. Applied Java naming conventions to refactor six constants to CONSTANT_CASE, directly addressing SonarCloud quality signals and improving code readability. Leveraged skills in Java, unit testing, and Git version control to implement the change in a single, traceable commit. This targeted update reduced the risk of naming-related regressions, simplified future code reviews, and strengthened the reliability of backend tests, supporting ongoing maintainability and adherence to best practices in software development and test automation.
