Detect visual changes and regressions with visual testing

Catch visual bugs before your customers do and ship visually perfect UI with every release.

What is Visual Testing?

Visual testing automates the detection of UI changes through screenshot comparisons, offering pixel-level precision, uncovering subtle differences, and broadening coverage.

Why do you need visual testing?

Automate the process of detecting visual changes and regressions before they slip into production.

Functional tests are not enough

Functional tests only check for behavioral outcomes, not UI changes. It is difficult to assert visual correctness with code.

Manual testing is not scalable

Applications today run into hundreds of screens and components. Checking all of them for visual consistency manually is inefficient.

Responsive tests are complex

Visual testing compares each configurable responsive width against the baseline and helps you automate responsive testing.

Increase your test coverage with visual testing

Visual testing complements existing test suites by detecting visual bugs and regressions in websites or apps. It doesn't replace functional validation but ensures visual integrity and appearance.

Detect visual changes with accurate comparisons and deliver pixel-perfect software with every release.
