Regression Testing

Ship changes without wondering what you broke

Applitools compares every release against your last known-good baseline with Visual AI. When something breaks, you get a reproducible bug to fix, not a coin flip to debug.

Catch what changed

Compare every release against your last baseline. Applitools flags the pixels a user would actually notice, not every rendering quirk that showed up in the diff.

Trust the result

The same screenshot always passes or always fails. A red build means a real regression, not something you re-run and hope goes away.

Update baselines in one click

When a change is intentional, group every test it affects across browsers and devices, and approve the new baseline once.

How Visual AI catches regressions your test suite doesn't

Catch bugs your functional tests can't see

Compare what renders, not just what runs A test can pass every assertion and still ship a broken layout. Visual AI checks the actual page against your baseline, not just the code path that ran.

Cover every browser and device automatically The Ultrafast Grid runs your regression suite across hundreds of browser and device combinations in parallel without a local device lab to maintain.

Know in seconds if it's a bug or a change

See the exact change Root Cause Analysis shows the exact DOM and CSS change behind every diff, so you know in seconds whether it's a real regression or an intentional update.

Trust every red build The same screenshot always passes or always fails. A failure is a real bug you can trace, not something to explain away with a re-run.

Run regression checks in the pipeline you already have

Run in your existing pipeline SDKs integrate directly with Playwright, Cypress, Selenium, and Appium, so regression checks run in the same CI job as everything else.

Test components before they reach a page Catch a regression in Storybook or Figma at the component level, before it ships anywhere a user can see it.

Cut regression maintenance down to one click

Auto-maintenance for intentional changes Group every test affected by a real UI update and approve the new baseline once, across every browser and device it touched.

Locator-free execution Elements are found by visual and semantic clues, so a class name change during a refactor doesn't take down the whole suite.

Regression testing has never been more powerful using Visual AI

1

Broad regression coverage

Extend the same suite across web, mobile, and PDF documents, so a UI change doesn't slip through in a channel you didn't think to check.

2

Dynamic content handling

Choose the AI match level that works for you to control what counts as a regression, and let Applitools automatically ignore dynamic data like timestamps, session IDs, and A/B content instead of flagging it as a failure.

3

Cross-browser and -device coverage

The Ultrafast Grid and Native Mobile Grid render the same test across every browser and device in parallel, without a local grid to maintain.

4

Deterministic Language Model

The same input always produces the same output, so a result is something you can explain and trust, not a probability.

5

Human-eye simulation

Visual AI ignores rendering noise like anti-aliasing and sub-pixel shifts, and flags only the changes a real user would notice.

6

No-code and code authoring

Write regression checks in plain English, record a flow, or write code directly, so QA, design, and engineering can all add coverage.
