1 // This file provides a PermissionsHelper object which can be used by
2 // LayoutTests using testRunner to handle permissions. The methods in the object
3 // return promises so can be used to write idiomatic, race-free code.
5 // The current available methods are:
6 // - setPermission: given a permission name (known by testRunner) and a state,
7 // it will set the permission to the specified state and resolve the promise
10 // PermissionsHelper.setPermission('geolocation', 'prompt').then(runTest);
