PROFILE

Marcin Kolasinski

Worked on modernizing the CI/CD workflow for the splunk/addonfactory-workflow-addon-release repository, focusing on improving test environment parity and build reliability. Introduced a dedicated Python virtual environment to isolate development dependencies, ensuring unit tests ran exclusively against production dependencies for accurate production alignment. Enhanced workflow automation using GitHub Actions and Shell scripting, including dynamic Python version management to maintain consistency across installations and tests. Further strengthened the pipeline by updating error handling so builds would fail if development dependency files were missing, surfacing issues early and improving feedback loops. The work emphasized reproducibility, clean environments, and robust CI/CD practices throughout.

2025-10 monthly summary: Strengthened CI reliability for the addon release workflow by hardening the GitHub Actions pipeline to fail when dev_deps/requirements_dev.txt is missing, ensuring missing development dependencies surface as a build environment issue rather than a false pass. This change reduces mask-free failures, accelerates remediation, and improves release confidence across the repo splunk/addonfactory-workflow-addon-release.

September 2025: Delivered CI/CD Workflow Modernization and Test Environment Parity for splunk/addonfactory-workflow-addon-release. Consolidated CI/CD improvements to isolate development dependencies, introduced a dedicated test virtual environment, enforced production dependencies in unit tests for production parity, and maintained Python version consistency across installs and tests. The work was implemented through four commits targeting dev-deps handling, a separate unit-test venv, prod-deps in unit-tests, and dynamic Python version adjustments.
