UI Testing

What is UI Testing?

!

• Ensure UI Component-Based Software Architecture|Components (buttons, forms, menus, etc.) work as intended and follow design specifications. ^[qrxw70]
• Validate usability, making sure the software is intuitive, accessible, and provides a positive user experience. ^{[gx155p] [qrxw70]}
• Check layout and design—including colors, fonts, and responsiveness—across devices and screen sizes. ^[qrxw70]
• Assess compatibility with different browsers and operating systems. ^{[qrxw70] [a2j3yu]}
• Confirm accessibility for users with disabilities, adhering to guidelines like WCAG. ^[qrxw70]
• Evaluate error messages, security (such as input field validation), and compliance with standards or regulations. ^[qrxw70]

UI Testing Techniques

• Manual UI Testing involves testers manually interacting with the application through a Web Browser:
  • Planning test cases
  • Executing actions (clicking, typing, dragging)
  • Observing and recording issues (with screenshots, for example)
  • Reporting defects and verifying fixes by regression testing ^[gx155p]
• Automated UI Testing automates these interactions:
  • Developing test scripts with tools (like Selenium, Cypress, or Playwright)
  • Running scripts for repeated tests or on multiple configurations
  • Comparing expected to actual behavior automatically
  • Maintaining test suite as the UI changes over time ^[gx155p]

• Functionality: All interactive elements act as expected.
• Layout & Design: Visual elements follow the required look, feel, and responsiveness.
• Usability: Defines how simple and intuitive the UI is for end-users.
• Compatibility: Verifies UI consistency across browsers, devices, and OS.
• Accessibility: Ensures usability for people with different abilities.
• Security & Error Handling: Prevents vulnerabilities and clarifies error messages.
• Compliance & Performance: Meets regulations and performs well under load.

!

• Regression Testing: Ensures new changes do not break existing UI functionality.
• Smoke Testing: Quick checks that the main UI flows are functioning after deployment.
• End-to-End Testing: Tests entire user workflows, crossing multiple screens or services.
• Browser/Device Compatibility Testing: Checks appearance and function on various platforms.
• Accessibility Testing: Uses tools and human evaluation for users with disabilities. ^{[3g9vbm] [qrxw70]}
