• Why visual testing for end-to-end testing frameworks
• How to get started with Percy for end-to-end testing frameworks
• Supported end-to-end testing framework SDKs

End-to-end testing frameworks are a powerful way to ensure that all moving parts within an application are configured correctly, and that the application's is functionally working correctly.

Percy integrates easily with end-to-end tests, adding an additional layer on top of those tests to ensure that everything always looks visually as intended.

Our Puppeteer SDK also provides a lightweight mechanism to simply visit URLs and add Percy snapshots—no existing tests needed.

Note: If you're not ready to integrate Percy into your testing framework, we recommend checking out our 2-minute example app tutorials.

How it works

At a high level, integrating Percy into your end-to-end testing framework is done in three steps.

Step 1: Install one of our SDKs into your test framework
Step 2: Add snapshots to your tests where you want visual coverage
Step 3: Configure and run visual snapshots as part of your workflow
