Sep 1, 2025

September 2025 monthly summary across two repositories: hmcts/prl-citizen-frontend and hmcts/prl-wa-task-configuration. Focused on reliability, correct time handling, and governance of gatekeeping rules. Key features delivered: - prl-citizen-frontend: Luxon-based timezone handling introduced to provide robust timezone support, addressing incorrect midday times in hearing data. Added tests around timezone edge cases and included Luxon usage guidance in the README. Also updated dependency management to include Luxon. Major bugs fixed: - CI/test stability across time zones: standardized test time zones (UTC and Europe/London) to eliminate flaky Jenkins results. - Gatekeeping behavior restoration for CA/DA cases in DMN (prl-wa-task-configuration): re-added sendToGateKeeper to the DMN task list, updated the associated DMN rule, and synchronized tests for CA-only scenarios. Overall impact and accomplishments: - Improved data correctness and reliability for hearing schedules, reducing misinterpretation of times. - Stabilized the CI pipeline across environments, speeding up integration and releases. - Restored expected business logic for gatekeeping in CA/DA cases, reducing regulatory risk and maintenance overhead. Technologies/skills demonstrated: - Luxon for robust timezone manipulation and dependency management. - Frontend testing strategies and test coverage improvements around time zones. - DMN rule adjustments and cross-repo test synchronization. - Documentation updates to improve developer guidance and onboarding.
