unit-testing - 我如何测试一个事件已经在 AngularJS 中广播？

Question

我只是想知道如何测试 handleAddClientBroadcast 事件？

我有这样的导航服务:

angular.module("ruleManagement.services")
    .factory('navigationService', function ($rootScope) {

        var navigationService = {};

        navigationService.prepForBroadcast = function() {
          this.broadCastIsAddClientItem();
        };

        navigationService.broadCastIsAddClientItem = function() {
          $rootScope.$broadcast('handleAddClientBroadcast');
        };

        return navigationService;
    });

我将此导航服务注入(inject)到我的 clientsCtrl 中并捕获 handleAddClientBroadcast，如下所示:

$scope.$on('handleAddClientBroadcast', function () {
  $scope.clientModel = {
    id: 0,
    name: "",
    description: "",
    rules: []
  };

  var lastClient = _.findLast($scope.clients);

  if (typeof lastClient == 'undefined' || lastClient == null) {
    lastClient = $scope.clientModel;
  }

  $scope.clientModel.id = lastClient.id + 1;
  $scope.clients.push($scope.clientModel);
});

谢谢。

假设您正在使用 Jasmine

spyOn($rootScope, '$broadcast').andCallThrough();

...

expect($rootScope.$broadcast).toHaveBeenCalledWith('eventName');
