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