Developed comprehensive end-to-end tests for the Payment Operations Page in the juspay/hyperswitch-control-center repository, focusing on enhancing UI reliability and maintainability. Leveraging Cypress and JavaScript, the work centered on automating validation for column customization and search features, ensuring that default columns display correctly, users can toggle column visibility, and search filters results accurately. These tests were integrated into the continuous integration pipeline to provide rapid feedback and reduce manual QA effort. By expanding test coverage for key user interactions, the developer enabled faster iteration on payment operations features and improved confidence in the accuracy of data presentation within the UI.
