未定义不是评估Expect.toBeDefined的函数

Question

我得到了一个使用angularJS的项目，我试图在该项目中运行单元测试，但因果响应会导致错误评估任何匹配器的expec。在这种情况下，我使用的是toBeDefined，但是无论如何我都会遇到相同的错误。我使用的版本是：Karma-Jasmine：^ 2.01，Karma：3.1.4。

describe('EventsCtrl', function() {
beforeEach(module('app'));

var $controller, $rootScope;

beforeEach(inject(function(_$controller_, _$rootScope_){
  $controller = _$controller_;
  $rootScope = _$rootScope_;
}));

describe('$scope.fileName', function() {
  it('bla bla bla', function() {
    var $scope = $rootScope.$new();
    var controller = $controller('EventsCtrl', { $scope: $scope });
    $scope.fileName = 'data';
    expect($scope.fileName).toBeDefined();
  });
});
});

这是我的Karma.conf

module.exports = function(config) {
config.set({

但是当我运行测试时出现此错误：
