PROFILE

Jan-willem Harmannij

Worked on the os-autoinst/os-autoinst-distri-opensuse repository to deliver and stabilize automated test suites for the Aeon distribution, focusing on first boot, installation, and encryption scenarios. Developed features using Perl and YAML, including standardized encryption passphrase handling and installer configuration updates to improve deployment flexibility and test reliability. Enhanced asset reuse by restructuring needle directories and implementing symlinks, while also refactoring code and documentation for maintainability. Addressed bugs affecting test imports and needle storage, reverting changes to ensure consistent editor workflows and reduce maintenance risk. Demonstrated skills in backend development, configuration management, and test automation within a cross-repository environment.

February 2026: Focused on stabilizing Aeon needles storage in the os-autoinst/os-autoinst-distri-opensuse repository. No new features delivered this month; primary accomplishment was a critical bug fix that reverts prior changes to Aeon needles storage, removing the placeholder directory and avoiding configuring NEEDLES_DIR to the OpenSUSE repository. This improves test execution reliability and editor workflows, reduces maintenance risk, and clarifies needle lifecycle across environments.

January 2026 (2026-01) Monthly summary for Aeon-focused development across the os-autoinst repository family. The month delivered concrete features, stability improvements, and cross-repo collaboration that directly enhance deployment flexibility, test reliability, and maintainability. Key features delivered: - Aeon RC3 Test Suite for First Boot and Installation: Introduced the Aeon RC3 distribution with initial first-boot and installation test cases. (commit 1b2197adf2d296de295a62beee8072e02cea810c) - Enhance Aeon Test Reliability for Encryption Passphrase: Standardized the encryption passphrase handling to a common password to improve test reliability and maintainability. (commit 3a13d6cfe444a41d838087522d27aa1298a74bcf) - Installer Configuration Update for Aeon: Updated the flavor and version in the Aeon template to reflect a new installer configuration, increasing deployment flexibility. (commit 098fe5e67e891fc56d74660516398544a9002318) - Shared Needle Files via Symlink and Aeon Needles Directory Restructure: Created a symbolic link from aeon/needles to opensuse/needles for cross-product access and restructured the needles directory for Aeon alignment. (commits d176f8b1b7819afe563c783eacdb3f660e91469e; 1403c03630433f0055a36184103673ca9e2eb094) - Code Quality Improvements: Refactor of Firstboot and cleanup of documentation/maintainer info to improve readability and maintainability. (commits 57f74cc22571f701ae9abe9f4d7e74ecbf8ad902; 575c43b8f427cc45ea3c574c930f794ba66b7b3a) Major bugs fixed: - Fix Test Import for Utils in firstboot.pm: Added missing import for the 'utils' module to enable test utilities. (commit 9982a39f60f97561b8c3212e313adf4a87d14d56) - Improve First Boot Test Coverage and Tik Encryption Setup: Refined is_aeon() and updated test scripts to improve the first boot flow and ensure proper screen assertions during Tik encryption passphrase setup. (commit d7e879ec1b469a0adcdf9909d30a6901ce1c346b) Overall impact and accomplishments: - Strengthened automated testing for Aeon with more reliable first-boot and encryption paths, reducing flaky tests and accelerating feedback loops. - Increased deployment flexibility and scaling across OpenSUSE distributions through installer template updates and YAML configuration enhancements. - Improved cross-repo asset reuse and test hygiene via shared needles, symlinks, and targeted code quality improvements. Technologies/skills demonstrated: - Test automation framework design and maintenance, encryption handling in tests, and robust is_aeon() logic. - Filesystem operations: creating and leveraging symlinks, reorganizing needles directories, and path normalization. - OpenQA integration and YAML-based deployment configurations, with maintainership and documentation improvements for long-term sustainability.
