# About Testing Your App

Before distributing your app, test its functionality to make sure it works as expected. Wix provides tools for:

- **Functional testing**: [Test your app](https://dev.wix.com/docs/build-apps/launch-your-app/app-distribution/test-your-app/test-your-app-on-a-premium-site.md) on a free premium site, and share a test link with collaborators.
- **Pre-submission checks**: Confirm your app meets all [technical and listing requirements](https://dev.wix.com/docs/build-apps/launch-your-app/app-distribution/test-your-app/app-checks-and-testing-guide.md) before submitting to the Wix App Market.
- **Upgrade flow testing**: If your app has pricing plans, [test the full purchase and upgrade flow](https://dev.wix.com/docs/build-apps/launch-your-app/app-distribution/test-your-app/test-your-app-s-upgrade-process.md) to verify your app responds correctly to billing events before distributing.
