Question

我刚开始对我的应用进行单元测试，并成功运行了一个测试套件，是的！我继续开始测试第二个控制器，一旦测试运行器（karma）遇到inject块，测试就会失败。评论它，测试再次通过。不能为我的生活找出可能发生的事情。非常基本的业力配置：

https://gist.github.com/ggoforth/82510af339370a4dca32ad4c0c4b0563

控制器看起来像：

angular.module('somemodule')
  .controller('SomeCtrl', SomeCtrl);

function SomeCtrl($rootScope, Notification) {
  $rootScope.$on('someapp.apiLimitExceeded', (evt, err) => {
    Notification.error({
      message: err.data.message
    });
  });
}

第一个测试看起来像：

describe('SomeCtrl', () => {
  let $rootScope, controller, notification;

  beforeEach(() => {
    module('mymodule');

    inject(($injector) => {
      $rootScope = $injector.get('$rootScope');
      notification = $injector.get('Notification');

      spyOn(notification, 'error');

      controller = $injector.get('$controller')('SomeCtrl', {
        $rootScope: $rootScope,
        Notification: notification 
      });
    });
  });

  describe('Initialization', () => {
    it('Should register a $rootScope listener for mymodule.apiLimitExceeded', () => {
      const args = {data: {message: 'dis an errr'}};
      $rootScope.$emit('mymodule.apiLimitExceeded', args);

      expect(notification.error).toHaveBeenCalled();
      expect(notification.error).toHaveBeenCalledWith(args.data);
      expect(notification.error.calls.count()).toBe(1);
    });
  });
});

此测试按预期通过。如果我将此文件的内容复制并粘贴到另一个测试文件中，而不更改任何内容，则测试开始失败。删除第二个测试文件会使原始测试开始通过。我必须遗漏一些关于业力如何运行这些角度测试的事情，或者一些我没有表现的泪水，但我看不出那可能是什么。有任何想法吗？我得到的错误，供参考：

更新

问题在于我使用的是未转换的ES6，其中包括使用胖箭头函数进行注入块。显然Chrome 50/51存在问题，您必须使用正常功能。将胖箭头版本更改为正常功能可修复问题（或通过babel预处理器转换测试文件）。

使用胖箭头函数时，Jasmine注入函数失败
