Visual Regression Testing: A Practical Guide for QA Teams

Visual regression testing (VRT) compares screenshots of your application against approved baselines. When CSS, fonts, or layout shift, you see a pixel diff — not a vague "something looks off" report.

Why VRT matters

- Catch unintended UI changes from refactors, dependency updates, or CMS edits

- Scale across viewports — phone, tablet, desktop in one run

- Integrate with CI so regressions block merges

How VisualQ helps

1. Create scenarios for the pages that matter

2. Capture baselines as your source of truth

3. Run tests on every deploy and review diffs in the viewer

4. Approve intentional changes as new baselines

Getting started

Sign up at visualq.ai, create a project, and run your first baseline capture. The AI Coach can crawl your site and suggest scenarios automatically.
