Sep 1, 2025September 2025 Harja: Delivered a reliability and maintainability refresh across migrations, data models, environment, and UI. Key outcomes include migration renaming and ordered execution with a two-pass approach for deletions and additions, a major refactor of the migration history data model for easier access to change data, and groundwork for multi-year persistence. Environment updates (Node.js, Cypress) and test scaffolding improvements boosted CI stability. UI/UX enhancements included a totals row for persistent changes, accessibility improvements, layout refinements, and removal of legacy debugging artifacts. Backend groundwork added support for storing multiple cost impacts per change and preparing previous-year persistent changes. Comprehensive test improvements and analytics fixes improved reliability of release validation.

Aug 1, 2025Month: 2025-08 – Harja (finnishtransportagency/harja) delivered targeted reliability improvements, stronger test stability, and CI automation refinements to accelerate PR validation and reduce production risk. Key features and fixes implemented in August are summarized below with business value implications. Key features delivered: - Cypress Dependency and Node Engine Alignment: Moved Cypress to devDependencies and aligned the Node engine version; updated build/scripts accordingly to reflect development-only Cypress usage. This reduces production footprint and clarifies tooling boundaries for developers. - End-to-End Test Stability Improvements: Introduced timeouts for loading states and refactored test setup to ensure consistent test initialization; results in more reliable E2E runs and faster, more predictable test cycles. - Clj-kondo Hooks for taoensso/encore: Added hooks for defaliases, defn-cached, and defonce; adjusted defalias hook mapping; introduced taoensso_hooks.clj for implementation; improves static analysis and linting quality for the Clojure components. - Pin GitHub Actions download-artifact to v5.0.0: Updated workflow files to pin actions/download-artifact to v5.0.0, enhancing CI reliability and reproducibility. - Cypress Click Reliability Fix: Removed force: true from Cypress click actions to ensure elements are actionable before interaction, reducing flaky tests. - Skip tuck-remoting notifications tests for stability: Temporarily skipped integration tests for tuck-remoting notifications to stabilize the overall test runs. Major bugs fixed: - Flaky E2E test issues and Cypress interaction reliability addressed through timeouts and removing force-based clicks. Overall impact and accomplishments: - Improved test reliability and CI stability, enabling faster feedback cycles and more predictable PR validation. - Clearer development tooling boundaries and more consistent build scripts, reducing maintenance overhead. Technologies/skills demonstrated: - JavaScript/Node.js, Cypress, GitHub Actions, E2E test design, test stabilization techniques, and Clojure tooling (clj-kondo) for static analysis improvements.
