PROFILE
Richard Werkman
Worked extensively on the stryker-mutator/stryker-net repository, delivering modular test runner abstractions, Microsoft Test Platform integration, and automated coverage analysis to enhance test reliability and maintainability. Leveraged C#, .NET, and GitHub Actions to refactor interfaces, implement dependency injection, and modernize build and release pipelines. Improved developer onboarding with updated documentation and Visual Studio Code setup, while strengthening CI/CD workflows and secure coding guidance aligned with OWASP standards. Automated release processes and streamlined tagging reduced manual overhead. Focused on robust logging, test automation, and dashboard observability, enabling more stable pipelines and clearer feedback for contributors across diverse development environments.

Feb 1, 2026February 2026 monthly summary for stryker-mutator/stryker-net: Delivered initial file-based coverage analysis for the Microsoft Test Platform (MTP) test runner and a README Star History section. Major bug fixes and stability improvements around MTP coverage integration, including integration-test validation, MSTest/MTP results handling, and hardened path validation. Renamed the coverage-related option to test-runner and updated documentation. Overall impact: enhanced test coverage visibility, improved test reliability and performance of the MTP workflow, and increased community engagement. Technologies demonstrated: .NET/C#, Stryker.Core, unit testing, test runner integration, path validation, coverage data handling, and cross-team collaboration.

Jan 1, 2026January 2026 focused on expanding test execution capabilities in the stryker-net project by delivering a preview version of the Microsoft Test Platform (MTP) testrunner. The feature is accessible via a new CLI option (--testrunner mpt) and includes a safe fallback path when coverage analysis is not yet implemented. Project auto-detection for MTP is not supported yet; this remains a manual action for now. A clear preview warning is shown to users to set expectations and avoid misinterpretation of results. This work establishes the foundation for broader MTP compatibility and prepares for future parity with existing testrunners, with emphasis on stability and backward compatibility.
