Documentation: Prerelease Testing and Selfhosting to test against preview channels of WebView2

[victorhuangwq]

Why test against preview channels of WebView2?

Evergreen WebView2 is based on the evergreen Chromium platform, which receives monthly major updates. Regressions in WebView2 apps tend to be application-specific, rather than affecting all WebView2 apps. WebView2 is tested in a variety of general scenarios, but it's possible that some of the specific scenarios of your app are not covered.

Finding these app-specific regressions and reporting them helps prevent them from being shipped in the Stable Evergreen WebView2 runtime.

What is prerelease testing and selfhosting?

Prerelease testing and selfhosting are our recommended ways of testing your WebView2 app against the preview channels of WebView2 runtime in Microsoft Edge.

• Prerelease testing is the automated testing of your app with a preview version of the WebView2 Runtime. See Prerelease testing using preview channels
• Selfhosting is a manual testing method, where you deploy a preview version of the WebView2 Runtime with your app to be use daily by your own development team. See Self-host by deploying preview channels.
