Question

我正在尝试创建“Angular.js in Action”中描述的Jasmine单元测试。该应用程序正常运行，但在尝试运行我的测试时，我在node.js命令提示符下不断收到此错误。

我的配置：

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

// base path, that will be used to resolve files and exclude
basePath: '',


// frameworks to use
frameworks: ['jasmine'],


// list of files / patterns to load in the browser
files: [

  'javascripts/angular.min.js',
  'javascripts/angular-mocks.js',
  'javascripts/app.js',
  'tests/angelloModelSpec.js',
  ],

我的index.html标题：

<head>
    <script src="javascripts/angular.min.js" type="text/javascript"></script>
    <script src="javascripts/angular-mocks.js"></script>
    <script src="javascripts/app.js"></script>


    <meta charset="utf-8">
    <title>Angello</title>
    <meta name="description" content="Angello Story Application">
    <link rel="stylesheet" href="app.css">
</head>

我的测试：

describe('Service: angelloModel', function(){

// load the service's module
beforeEach(module('Angello'));

var modelService;

// Initialize the service
beforeEach(inject(function (angelloModel){
    modelService = angelloModel;
}));

describe('#getStatuses', function(){
    it('should return seven different statuses', function () {
        expect(modelService.getStatuses().length).toBe(7);
    });
});
});

在命令提示符下输出

：

Answer 1

通常这是由于角度版本冲突，karma.conf.js中脚本定义的顺序错误，导入不完整或语法错误造成的。

由于我可以看到您正在测试服务，请在文件下包含该服务的js文件（除非它嵌入在app.js中）并删除错误放置的逗号（见下文）：

files: [

'javascripts/angular.min.js',
'javascripts/angular-mocks.js',
'javascripts/app.js',
'<include your service js here>',
'tests/angelloModelSpec.js', <<-- and remove this trailing comma
],

Answer 2

我发现了问题！我正在编辑错误的配置文件！我正在编辑app目录中的配置文件，但真正的配置文件位于C：\ Users \ myUsername \ karma.conf.js

感谢您的帮助！

Answer 3

您必须将 angular.min.js 文件放在您自己的 app.js 文件之上的 angular-mocks.min.js 文件之上。

files: [
  'https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js',
  'https://cdnjs.cloudflare.com/ajax/libs/angular-mocks/1.8.2/angular-mocks.min.js',
  'https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js',
  'js/app.js',
  ...
],
