Month: 2026-01 — Delivered Test Infrastructure Performance Optimization for alphagov/pay-connector, implementing a faster, more deterministic test suite. Refactors reduced database migration and reset overhead, enabling quicker CI feedback. Key changes include running migrations once per JVM, switching WireMock resets to resetRequests(), using @AfterAll for DB truncation, and consolidating truncation to a single statement via DatabaseTestHelper.truncateAllData(). This work reduces test setup/teardown time and stabilizes tests across environments.

Month: 2025-12 summary focused on OpenAPI schema modernization, build stability, and cross-repo API contract improvements across key services. This work reduces deprecated usage, eliminates compilation warnings, and strengthens client integration readiness. Key achievements delivered: - OpenAPI schema modernization across pay-connector, pay-publicapi, pay-adminusers, and pay-products, replacing deprecated 'required' fields with current counterparts (e.g., requiredMode) to align with latest specs. Commits include 36ceda613e7ea2f84b70bd8a4f6d0a03c8d7b09b; 0fafa7b36d304a33fc266e41f77d53d8fb30a1b1; c14a599308ee63d5e40c5eda15ae2af7b613376b; 7af921842494f58c3206acae832cc5332f32f957. - Reduced build-timeWarnings by updating OpenAPI usage per Swagger-core v2.2.32 guidelines, eliminating repeated deprecation warnings during compilation. - Strengthened API contract stability and client integration readiness by standardizing schema across services, enabling easier maintenance and future API evolutions. - Demonstrated cross-repo collaboration and traceability with explicit commits and PR-level documentation, improving auditability for compliance and performance reviews.
