Design, develop, and maintain automated end‐to‐end test cases using Cypress Test across Chromium, Firefox, and WebKit browsers. Use Cypress recommended locator strategies t o create resilient selectors that reduce flakiness. Implement structured automation architecture using fixtures, reusable components, Page Object Models, and modular test design. Analyze functional requirements and translate them into scalable test plans and automation suites. Execute automated test suites in CI pipelines and ensure stable, repeatable test outcomes. Validate application functionality across Chrome/Edge (Chromium), Firefox, and Safari (WebKit) using a unified Playwright API. Ensure consistent behavior across OS platforms (Windows, macOS, Linux). Integrate automated tests into modern CI/CD pipelines such as GitHub Actions, Jenkins, Azure DevOps, or GitLab. Implement robust validation strategies including accessibility checks, performance considerations, and negative test coverage. Work closely with developers, product owners, and QA teams to identify test scenarios, defect patterns, and gaps in automation. Participate in code reviews, provide feedback on testability, and advocate best practices for automation.
