Mira Dietschmann contributed to the bettercodepaul/swt2-bsa-backend repository by refactoring the SchuetzenstatistikLetzteJahreDOTest class to standardize constant naming, addressing SonarCloud quality signals in the process. Using Java and Git, Mira improved test code readability and maintainability by renaming six constants to follow the CONSTANT_CASE convention. This targeted change enhanced the consistency of the unit test suite and reduced the risk of naming-related regressions. By linking the commit to tracked SonarCloud issues, Mira ensured traceability and compliance with quality gates. The work demonstrated a focused approach to code quality, emphasizing maintainable software development and effective use of automated quality tools.
