Visual Regression (Percy)

Catch UI bugs automatically. Implement pixel-perfect Visual Regression Testing using Percy or Applitools in your CI/CD pipeline.

Functional tests miss CSS bugs. Visual Regression testing catches what functional tests don't: layout shifts, color changes, and broken images. This course teaches you to integrate visual testing tools like Percy or Applitools into your automation framework (Cypress/Playwright). You will learn to manage baselines, approve/reject diffs, and handle dynamic content to avoid flaky tests. Essential for ensuring your app looks as good as it works.
