Over seven months, Peter Hedenskog engineered reliability and observability improvements for the hallowelt/mediawiki repository, focusing on Selenium-based test automation and CI/CD pipelines. He modernized API interactions by replacing mwbot with Node.js fetch, refactored test harnesses for WebdriverIO v9, and integrated Prometheus metrics for actionable telemetry. His work included stabilizing end-to-end tests, enhancing error logging, and ensuring deterministic CI outcomes through browser version pinning and Docker configuration. By internalizing API calls and exposing a stable developer interface, Peter reduced maintenance overhead and improved security. He primarily used JavaScript, Node.js, and Selenium, demonstrating depth in test automation and release management.

In Oct 2025, delivered security hardening and API modernization for hallowelt/mediawiki. Replaced insecure mwbot with built-in Node.js fetch for Selenium API interactions, and released MediaWiki API Interaction Modernization (WDIO-MediaWiki 6.0.0) internalizing API calls and improving CI stability.

September 2025 accomplishments for hallowelt/mediawiki focused on test stability and API readiness. Key outcomes include: 1) Selenium Test Environment Enhancements: added logging of the base URL used in tests and disabled Chrome infobars to reduce test interface noise, improving debugging efficiency and test reliability. 2) Selenium API Abstraction Refactor: introduced a createApiClient factory and an Api class, decoupling mwbot from the API and delivering a stable external interface. These changes lay the groundwork for removing mwbot and for easier future integrations. Business impact includes faster debugging, lower maintenance cost, and more predictable automation behavior.
