Prudhvi Maddineni focused on enhancing the reliability and maintainability of confidentiality workflows in the hmcts/prl-cos-api repository. Over the course of a month, Prudhvi expanded test data and coverage for confidentiality scenarios, particularly around FL401 mappings and Refuge Case generation. Using Java and Mockito, Prudhvi implemented robust unit tests for the RefugeCaseGenerator and refactored existing tests to align with updates in the ConfidentialDetailsMapper. These targeted improvements reduced regression risk and improved code quality, enabling safer deployments. The work demonstrated depth in backend development and unit testing, with a clear emphasis on strengthening end-to-end confidence in sensitive case handling.
