javascript - 运行单元测试时 Promise 回调不执行

Question

我想测试以下 Controller :

angular.module('myApp').controller('OrderController', ['$scope', 'retryRequest', 'ORDER_STATUS_URL', 'MAX_RETRY',
 function ($scope, retryRequest, ORDER_STATUS_URL, MAX_RETRY) {
  retryRequest(ORDER_STATUS_URL, 'GET', MAX_RETRY).then(function(data) {
    $scope.order = data;
  }).catch(function(data) {
    $scope.error = data.ErrorMessage;
  });
}]);

测试:

describe('Order Controller', function () {

  beforeEach(module('myApp'));

  var $controller, $q;
  beforeEach(inject(function (_$controller_, _$q_) {
    $controller = _$controller_;
    $q = _$q_;
  }));

  describe('When I access order data', function() {
    it('I expect Id to be set', function() {
      var mockRetryRequest = function(){
        var deferred = $q.defer();
        deferred.resolve({ 'OrderId': 'foo' });
        return deferred.promise;
      };
      var $scope = {};
      var controller = $controller('OrderController', { $scope: $scope, retryRequest: mockRetryRequest });
      assert.equal($scope.order.OrderId, 'foo');
    });
  });
});

这会导致 $scope.order 未定义。模拟已注入(inject)，但 promise 不会调用回调(然后)。

可能的候选者是 Mocha 设置。

摘要循环不运行。调用$rootScope.$digest();
