February 2026 monthly summary for Altinn/altinn-profile focusing on feature delivery and testing enhancements. Delivered two major features that enhance testing capabilities and authentication reliability, laying groundwork for scalable QA and stronger security. Key features delivered in this period: - Bruno Testing Environment - Multi-User Support: Centralized shared user definitions and dynamic pre-request loading to support multiple users during Bruno testing sessions. This enables more realistic and efficient end-to-end test scenarios. Commit: 1d7c95bcbfb70d64596972871b93ce83a8e71f05 (Feature: multiple users in bruno). - Address Verification System: New address verification system with tables for verification codes and verified addresses, strengthening user authentication workflows. Commit: 2995c92a2e49d5f9682d03c0bf62a774df6d8c20 (First sketch of verification codes tables). Impact and value: - Improves testing fidelity and coverage by enabling multi-user scenarios and robust validation flows during authentication. - Reduces manual setup for tests and accelerates iteration cycles in QA. - Sets foundation for scalable user verification processes and enhanced security posture across the profile repo. Technologies/skills demonstrated: - Test environment engineering (multi-user orchestration, dynamic data loading) - Database/table design for verification codes and verified addresses - Git-based collaboration and traceability through commits
