April 2025 monthly summary focusing on delivered CAS2 v2 data handling and UI/reporting improvements across two repositories, with a strong emphasis on business value and robust test coverage. Key features delivered: - CAS2 v2 Subject Access Request (SAR) data handling: new repository for detailed SAR data (applications, assessments, notes, status updates, domain events) integrated into the SAR service; added test factories and integration tests. Representative commit: e2eb83d77900e649a99e2374ee708183517ac3c9. - CAS2 v2 Submission NOMIS flexibility and data model enhancements: submissions allowed without NOMIS numbers; NOMIS data optional; models updated; submitted/unsubmitted report data handling adjusted for missing NOMIS. Representative commits: c1d553c016af4c5fcad6173409354a8b4d0255af, bc6511bd56babb24654cf3f0f60d8ddb66617a72, 866ded68507e54f463272b58dda98be9e98a0af0, 050b233268ddbdd87c47e20b1be11295ac2446c4, 7659ac635ef0674246459532787ac609416c3295. - CAS2 v2 Application Origin Tracking in events: added applicationOrigin to Cas2ApplicationStatusUpdatedEventDetails and propagated origin through event details for better tracking. Representative commits: 03f5ca42184f3e49307845ce855cf4b754f91543, f4b697ce8972df048a70596d028ff8a9ddb32e99. - CAS2 v2 Reports Data Modeling and Date Formatting Enhancements: reordered columns, added fields, nullable NOMIS fields, and ensured UTC timestamp formatting; expanded test coverage. Representative commits: dc2bcfd9bd689e67a1a83132473de97bcbab731e, fb1411639560be18e2f16a22a5e137b4fe549f0e, 45c8051fe4df3161eba4bb4d3e904e656eb3d306, 84d3946f4fe6229a791a8a1fc00a5c93437fade1, 9188468ff331d2a07a164c192aa269006efcc852, 05b6372cc8aee802d294cb91c2e1c1bee3a32129, c9183cc551457a39de8f60ac4037232e150d0469. - CAS2 v2 User-facing text and error handling improvements: clearer status descriptions and improved 'not found' error handling; updated related tests. Representative commits: fd8398e4a5b4807f9ac46ade19216dede83a178d, 1b2f1d66a5d40d9fe04be96d32990b6cd63ad619, 90bd727d2f1238434d71282352944705ffd05b2b. Major bugs fixed: - Improved user-facing text for not-found scenarios in CAS2 v2 and updated unit tests accordingly, reducing user confusion and support effort. Representative commits: as above for user-facing text. Overall impact and accomplishments: - Improved data completeness and accessibility for CAS2 v2 SAR data; greater flexibility in submissions without NOMIS data; enhanced event traceability and reporting fidelity; broader UI/reporting consistency and accuracy; higher test coverage leading to more reliable releases. Technologies/skills demonstrated: - Data modeling and nullable fields handling, UTC date formatting, event-driven tracking, test factory and integration test development, UI copy and labeling consistency, and comprehensive test coverage across backend and frontend components. Business value: - Enables safer, compliant SAR workflows, reduces data gaps for incomplete NOMIS data, improves decision-making with richer, clearer reports, and elevates user experience with improved messaging and UI consistency.
