Visual Testing
Visual testing is a testing technique that verifies the visual appearance of an application by comparing its user interface against expected visual baselines.
“Testing that uses image recognition to interact with GUI objects.”

View the complete ISTQB GlossaryWhat is Visual Testing?
It detects unintended changes in layout, colors, fonts, images, spacing, and other visual elements that functional tests may not identify.
Appearance validation: Focuses on the user interface.
Automated comparison: Often uses image comparison tools.
Complements functional testing: Detects visual regressions.
Real World Example
A regulated product team is preparing a release where Visual testing appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Visual 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 Visual testing and similar ideas.
The page becomes useful in practice because Visual testing is connected to a specific testing decision, not memorized as a detached definition.
