Worked on the leancodepl/patrol repository to deliver a new web port configuration feature for web tests, introducing a --web-port command line option that allows developers to specify the web server port during test runs. This enhancement, implemented using Dart and command line interface skills, addressed previous limitations in test environment flexibility and reliability. The work included updating the changelog for better traceability and fixing a development-mode web support issue to ensure compatibility with existing workflows. By aligning web server and Chrome browser flags, the changes improved test fidelity and usability, supporting more robust and adaptable full stack development practices.
