Over a two-month period, contributed to the spryker/cypress-tests and related Spryker repositories by building and refactoring end-to-end test suites and GUI modules for product measurement units. Focused on enhancing test reliability and maintainability, the work included implementing repository-pattern selectors, dynamic fixtures, and shared test helpers using JavaScript, TypeScript, and PHP. Developed and integrated a measurement units GUI module across b2b-demo-marketplace and b2b-demo-shop, improving user experience and supporting robust release cycles. Emphasized configuration management, dependency stabilization, and fixture management to streamline UI testing workflows, resulting in more stable, maintainable, and comprehensive test coverage for measurement unit features.
