Protocol Handling Web Platform Test

This test validates that an install application can register URL protocol handlers via a property in the web app manifest. The app should open directly when the 'web+testing' custom-scheme URL is visited.

Manual Test Steps:

  1. Install this app.
  2. Launch 'web+testing://test-url/'. Instructions will vary by OS.
  3. If your browser prompts you, allow the app to open.
  4. The app window that opens should indicate success of this test.
