Screenshot-based regression checks across desktop, tablet, and mobile viewports.
Baseline management to commit and track approved UI appearances over time.
CI integration to automatically run tests and report diffs with inline highlights for quick reviews.

Quick Start

Run the Playwright visual regression tests in the e2e directory to validate current UI against baselines.

FAQPage Schema

How does Playwright visual regression testing detect UI changes across different viewports?▼

Playwright visual regression testing detects UI changes by capturing current screenshots across desktop, tablet, and mobile viewports, then automatically comparing them against committed baselines to identify unintended layout, style, and component differences.

What is baseline management for UI testing and how do I update it?▼

Baseline management for UI testing involves committing and tracking approved UI appearances over time. You update baselines by replacing the committed reference screenshots in the e2e directory after validating visual changes during manual QA or CI checks.

How do I run Playwright visual regression tests in CI to prevent unintended style changes?▼

You run Playwright visual regression tests in CI by executing the test suite in the e2e directory, which automatically compares current renders to baselines and reports visual diffs with inline highlights for quick review.

Can I use Playwright visual regression checks for both CI automation and manual QA?▼

Playwright visual regression checks support both CI-driven automated regression testing and manual QA workflows. You can run the e2e tests locally to validate current UI against baselines or integrate them into CI pipelines for automated diff reporting.

What is the best way to review visual diffs when Playwright UI regression tests fail?▼

The best way to review visual diffs from failed Playwright UI regression tests is using the inline diff reporting, which highlights specific layout, style, and component changes across multi-viewport screenshots for quick review and baseline updates.
