FAQs

What is visual regression testing, and why is it important?

Visual regression testing ensures UI changes don’t unintentionally break design or layout. By automating visual comparisons, teams can catch styling bugs, layout shifts, and inconsistencies that manual reviews might miss.

Why do I need visual regression testing if I’m already doing functional testing?

Functional testing validates expected behavior, but it doesn’t catch UI regressions like layout shifts, broken styling, or visual discrepancies. Visual regression testing ensures pixel-perfect consistency by detecting unintended UI changes early.

What is Percy, and how does it help with visual regression testing?

Percy automates visual regression testing in your existing CI/CD pipeline, capturing screenshots, comparing them against a baseline, and highlighting visual changes.

How easy is it to get started with Percy?

Getting started is seamless—install the BrowserStack SDK, configure Percy with a few lines of code, and run tests in your CI/CD pipeline. Percy automatically captures and compares snapshots, making visual testing effortless.

Does Percy support testing across different screen resolutions?

Yes, Percy allows testing across different screen sizes and breakpoints, helping teams validate UI changes across desktop, tablet, and mobile views to ensure a seamless experience.

Can I run Percy tests locally before committing changes?

Yes, Percy supports local testing, allowing developers to validate visual changes before pushing to a repository. This reduces noise in pull requests and ensures cleaner commit histories.

Is Percy free to use, and what are the pricing options?
