Sep 1, 2025September 2025 monthly summary for pagopa/pn-b2b-client focusing on webhook testing enhancements and robustness improvements. Key outcomes include delivery of Webhook Testing Enhancements with new retry-after scenarios, test refactoring to be parameterized across webhook versions, and a dedicated test class for webhook headers; major bug fix for bank courtesy message feature robustness with validation for the Send Courtesy Message timeline event and cleanup of an obsolete QA tag from a feature file. These efforts improved test coverage, reliability, and maintainability, reducing production risk and enabling faster iteration for webhook-driven integrations.

Apr 1, 2025Month: 2025-04 — concise monthly summary focusing on business value and technical achievements for pagopa/pn-b2b-client. Key features delivered: - AvanzamentoNotificheB2bSteps: added default implementations and MOST_RECENT version behavior via SharedSteps, simplifying maintenance and reducing boilerplate. - Code cleanup and packaging: removed unused methods from NotificationStepsInterface and related classes; removed Webhook Client classes (to be re-added later); moved files to more appropriate packages in phase 2; created separate enums for StreamVersion and NotificationVersion. - Improved API consistency: IPnWebRecipientClient updates, Javadoc cleanups, and method standardization across the codebase. - QA and test scaffolding: QA phase 1 updates, creation of separate Webhook V26 test suite, and development of test scenarios for QA-7074, QA-7346, plus QA7077 test enhancements. - Refactor and integration: phase-integration work including merge with Phase 1 branch and continuation refactor to consolidate AvanzamentoNotificheB2bSteps into a unified, readable structure. Major bugs fixed: - Fixed an undefined step in AvanzamentoNotificheB2bSteps. - NullPointer and ClassCastException fixes; stabilization of asyncValidation flow (removal of Lombok getter and addition of an omonymous handling when IUN is null). - Rename of NOTIFICATION_STATUS_NOT_REFUSED to NOTIFICATION_STATUS_CANCELLED with enhanced error messaging; removal of versionUsed to align with SharedSteps. - Numerous test-related fixes to address QA-7074 and QA-7346 failures, and updates to VerificaPagamentoSteps. Overall impact and accomplishments: - Significantly improved maintainability through refactoring and modularization, enabling faster future feature work and easier onboarding. - Increased test coverage and reliability via dedicated Webhook V26 tests and extensive QA scenarios; reduced flaky behavior in async validation paths. - Strengthened business value by stabilizing cross-module notification progression, aligning SharedSteps with AvanzamentoNotificheB2bSteps, and preparing the codebase for Webhook-based integrations. Technologies/skills demonstrated: - Java, Enum design (StreamVersion, NotificationVersion), and interface-driven refactors. - Packaging strategies and code cleanup (unifying methods, removing unused APIs). - Test automation and QA discipline (test suites, scenario-driven tests, and test fixes across multiple QA cycles). - Version control hygiene: multi-branch work, merges from Phase 1, and PR-driven refinements.
