使用es6角度测试服务等级

我有一个service class写在es6角度应用程序。它正在请求使用http的api数据。现在我想通过mocha and chai来测试服务。这里是我们的服务是什么样子：使用es6角度测试服务等级

"use strict"; 
const HTTP = new WeakMap(); 
class EventService{ 
    constructor($http, moment){ 
     HTTP.set(this, $http); 
     this.$http = $http; 
     this.url = 'http://test/api/events?'; 
     this.apiKey = '1234asd'; 
    } 

    getEvents(){ 
     return this.$http({ 
      url: this.url + 'from=' + this.from + '&to=' + this.to + '&apiKey=' + this.apiKey, 
      method: "GET", 
      crossDomain: true, 
      headers: { 
       'Content-Type': 'application/json; charset=utf-8' 
      } 
     }); 
    } 
} 


EventService.$inject = ['$http', 'moment']; 

export default EventService;

Karma.conf.js：

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

    // base path that will be used to resolve all patterns (eg. files, exclude) 
    basePath: '', 


    // frameworks to use 
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter 
    frameworks: ['mocha', 'chai'], 


    // list of files/patterns to load in the browser 
    files: [ 
     'node_modules/angular/angular.js', 
     'node_modules/angular-mocks/angular-mocks.js', 
     'node_modules/moment/moment.js', 
     'node_modules/angular-moment/angular-moment.js', 
     'lib/shared/services/events-service.js', 
     'tests/*.js' 
    ], 


    // list of files to exclude 
    exclude: [ 
    ], 


    // preprocess matching files before serving them to the browser 
    // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor 
    preprocessors: { 
    }, 


    // test results reporter to use 
    // possible values: 'dots', 'progress' 
    // available reporters: https://npmjs.org/browse/keyword/karma-reporter 
    reporters: ['progress'], 


    // web server port 
    port: 9876, 


    // enable/disable colors in the output (reporters and logs) 
    colors: true, 


    // level of logging 
    // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG 
    logLevel: config.LOG_INFO, 


    // enable/disable watching file and executing tests whenever any file changes 
    autoWatch: true, 


    // start these browsers 
    // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher 
    browsers: ['Chrome'], 


    // Continuous Integration mode 
    // if true, Karma captures browsers, runs the tests and exits 
    singleRun: false, 

    // Concurrency level 
    // how many browser should be started simultaneous 
    concurrency: Infinity 
    }) 
}

现在我只是想测试套件运行起来，但是，我收到以下错误，当我运行karma start：

Uncaught SyntaxError: Unexpected token export 
    at lib/shared/services/events-service.js

这是在服务的导出命令。我需要做一些配置更改才能完成这项工作吗？

我认为你需要将你的文件预处理成浏览器可读的格式。例如，可以使用karma-rollup-preprocessor，rollup-plugin-babel和es2015-rollup babel预设来完成此操作。所以，你的Karma.conf.js文件看起来像下面这样：

var babel = require('rollup-plugin-babel'); 

module.exports = function(config) { 
    config.set({ 
     basePath: '', 
     frameworks: ['mocha', 'chai'], 
     files: [ 
      'node_modules/angular/angular.js', 
      'node_modules/angular-mocks/angular-mocks.js', 
      'node_modules/moment/moment.js', 
      'node_modules/angular-moment/angular-moment.js', 
      'lib/shared/services/events-service.js', 
      'tests/*.js' 
     ], 
     preprocessors: { 
      'lib/shared/services/events-service.js': ['rollup'], 
      'tests/*.js': ['rollup'] 
     }, 
     rollupPreprocessor: { 
      plugins: [ 
       babel({ 
        'babelrc': false, 
        'presets': ['es2015-rollup'] 
       }) 
      ], 
      format: 'iife', 
      moduleName: '<your_project>', 
      sourceMap: 'inline' 
     }, 
     /* other config options */ 
    }); 
};

这是只有一个办法办法做到这一点，但你的文件都将捆绑并预处理到浏览器友好es5iife事先向被Karma运行。这应该消除你已经得到的。希望这可以帮助。
