Worked on enhancing test reliability for the Ostorlab/KB repository by addressing a bug in the JSON Categories Validation Test. Focus was placed on improving the validation logic so that error objects accurately reflect category validation against predefined groups, thereby increasing the reliability of category-related tests. Utilized Python and testing frameworks to stabilize the test suite, which reduced flaky test runs and aligned outcomes with continuous integration expectations. No new features were introduced during this period, as efforts were concentrated on quality assurance and maintaining data integrity within the test suite, ensuring more consistent and trustworthy validation results for future development.
