- * @ngdoc function
- * @name angular.mock.createMockWindow
- * @description
- *
- * This function creates a mock window object useful for controlling access ot setTimeout, but mocking out
- * sufficient window's properties to allow Angular to execute.
- *
- * @example
- *
- * <pre>
-    beforeEach(module(function($provide) {
-      $provide.value('$window', window = angular.mock.createMockWindow());
-    }));
-
-    it('should do something', inject(function($window) {
-      var val = null;
-      $window.setTimeout(function() { val = 123; }, 10);
-      expect(val).toEqual(null);
-      window.setTimeout.expect(10).process();
-      expect(val).toEqual(123);
-    });
- * </pre>
