UI testing

UI testing validates all user-facing components: ensuring visual elements and functional workflows perform flawlessly across every required platform and device.

UI testing (User Interface testing) verifies that an application’s visual elements (buttons, forms, menus) and user interactions function correctly across various browsers and devices (Source 4). This critical process simulates real user journeys: clicking, typing, and navigating through the application's core workflows (Source 4). Automation tools like Selenium, Cypress, and Playwright execute these checks efficiently, catching defects early to prevent costly post-release fixes (Source 4). Prioritizing UI testing ensures cross-platform consistency, confirms usability, and protects brand reputation by delivering a stable, intuitive interface to the end-user (Source 1).
