Gui Testing
GUI testing verifies that the graphical user interface behaves correctly, displays information properly, and provides a consistent user experience across supported environments.
“A test approach performed by interacting with a test object using a graphical user interface.”

GUI testing evaluates visual elements, navigation, layouts, user interactions, and interface behavior to ensure users can successfully operate the application.
Visual verification: Checks buttons, menus, dialogs, forms, and layouts.
Interaction testing: Validates navigation, input handling, and user workflows.
Compatibility: Verifies consistent behavior across supported devices and screen sizes.
Real World Example
A regulated product team is preparing a release where Gui testing appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Gui testing as interchangeable with nearby ISTQB terms. That makes test scope blurry and can lead to weak evidence for the release decision.
The tester anchors the discussion in the official definition, asks where the concept appears in the product, and designs examples that show the difference between Gui testing and similar ideas.
The page becomes useful in practice because Gui testing is connected to a specific testing decision, not memorized as a detached definition.
