May 2025 monthly performance summary for hmcts/prl-ccd-definitions. The month focused on FPVTL-626 enhancements in the Court Admin workflow, expanding test coverage for bundle creation, and UI refinements to improve user experience and reliability. Key outcomes include enabling the Court Admin (cwd_admin) module with CRUD for decision states and multi-state handling, substantial test coverage for bundle creation flows, and UX improvements such as a single confirmation page and a clearer Save and Continue action. Security and access controls were tightened by restricting FPVTL-626 functionality to superusers. Several targeted bug fixes stabilized the FPVTL-626 flow, including realigning migrate-case tests with the new behavior and correcting PR references. Representative commits across the month include FPVTL-626 sequences: initial Court Admin wiring and CRUD enablement (e.g., 6d2b9066, 5a593783, 0a85141c), UI adjustments and test reversions (55eaa545, fb7b03c6, 4c1621cc), createbundle flow tests (7eb359fe, 884e5347, 92a33528), tests for similar-to-createbundle (40c9b3e5, a34f1477, 1e0249eb, 6758a148, 9272ee42, b8f4555b), and access-restriction and UX improvements (243c565a, f409632b, 74de21de).

Month: 2024-11 — nfdiv-case-api focused on expanding matching coverage for divorce cases and cleaning up tests and configurations. Key feature: Enhanced cross-case divorce matching by introducing CaseDataOldDivorce, a transformation method, and updating CaseworkerFindMatches to process matches from both old and new cases, enabled by smarter CCD configuration. Major bugs fixed: removal of unused mock data methods in CaseworkerFindMatchesTest and alignment of Old Divorce configuration and Idam credentials naming, with tests updated accordingly. Impact: broader, more accurate matching across legacy and current cases, reducing manual triage and speeding processing; improved test maintainability and deployment reliability through clearer configuration. Technologies demonstrated: Java backend development, data transformation, CCD configuration, test refactoring, and configuration management.
