  • Visual regression testing with Playwright, Chromatic, or Percy to capture baselines and compare diffs.
  • Cross-device and multi-viewport validation, including desktop and mobile layouts.
  • CI integration to run tests on pull requests and deployments, with diff review and baseline updates.

Quick Start

Run a visual regression test suite against your web app using Playwright or Chromatic and review any diffs.

FAQPage Schema
How do I automate visual regression testing for my web application?▼

Automate visual regression testing by capturing UI baselines with Playwright or Chromatic, then comparing screenshots across builds to detect unintended visual diffs and ensure layout consistency.

Can I run Playwright screenshot testing across multiple device viewports?▼

Playwright screenshot testing supports cross-device and multi-viewport validation, allowing you to capture and compare visual baselines across both desktop and mobile layouts within your test configurations.

How does visual regression testing integrate with CI workflows?▼

Visual regression testing integrates with CI workflows by running screenshot comparisons on pull requests and deployments, enabling automated diff review and baseline updates directly within your pipeline.

What is the best way to manage screenshot comparison thresholds in UI testing?▼

Manage screenshot comparison thresholds by configuring per-project test settings that define acceptable visual diff limits, preventing minor pixel variations from failing your UI testing pipeline.

Does visual regression testing work with both Chromatic and Percy?▼

Visual regression testing works with Chromatic, Playwright, or Percy to capture baselines and compare visual diffs, allowing you to choose your preferred tooling for detecting unintended UI changes.
