Badging

This module contains the implementation of the Badging API.

API

See the explainer for details. The NavigatorBadge mixin interface is included by Navigator and WorkerNavigator, which exposes two methods: setAppBadge() and clearAppBadge().

setAppBadge(optional [EnforceRange] unsigned long long contents): Sets the associated app's badge to |contents|.
- When |contents| is omitted, sets the associated app's badge to "flag".
- When |contents| is 0, sets the associated app's badge to nothing.
clearAppBadge(): Sets the associated app's badge to nothing.

Testing

web_tests/badging/*.html tests that the API accepts/rejects the appropriate inputs (with a mock Mojo service that verifies that the interface sends the correct Mojo messages". These tests duplicate some of the tests from WPT (below) but with internal verification.

web_tests/external/wpt/badging/*.html tests that the API accepts/rejects the appropriate inputs. These tests do not test the internal state of the badge (because they have no visibility into it), only success/failure.
