Job title: QA Automation Engineer - Playwright - 4DPipeline Core Technologies: Playwright, Typescript/Javascript, Bitbucket, Jira, OpenAi Api, Claude Api, Spark, Beam. Tenure: March 2024 - Present Achievements: • Architected and implemented advanced automated UI testing frameworks using Playwright and JavaScript, encompassing a wide range of testing scenarios such as screenshot comparison, element interaction (clicks, searches), and robust fallback strategies (e.g., XPath, JavaScript injection) to handle Playwright failures. • Enhanced test reliability by integrating screenshot error capturing and video recording for failed tests, ensuring comprehensive debugging capabilities. Strategically utilized beforeAll and beforeEach hooks to optimize test setup and teardown processes, tailoring execution flows to specific test suite requirements. Conducted cross-device testing, achieving full coverage across mobile and desktop environments. • Created complex CI/CD pipelines with parallel test execution, leveraging sharding, shared artifacts, and blob storage for efficient test distribution and result aggregation. Additionally, implemented performance benchmarking tests to measure UI rendering times using Playwright’s built-in tools.Optimized test suites for scalability by introducing retry mechanisms, custom timeouts, and dynamic test data generation, resulting in a 40% reduction in test flakiness and a 30% improvement in execution speed. • Worked closely with data engineering teams to simulate edge-case scenarios in Spark/Beam dataflows, ensuring comprehensive validation from data ingestion to UI rendering.
