我是AngularJS,ES6和Karma的新成员。我配置3天的业力,所以它真的很烦人。我想在我的angular-videos-library应用程序中添加一些单元测试。
来自控制台的错误:

单元测试apis.spec.js
:
import { YoutubeService } from './youtube.service';
describe('Youtube api service', () => {
beforeEach(angular.mock.module('app'));
it('should get an ID from long youtube link', () => {
let link = 'https://www.youtube.com/watch?v=TFeSNOdNtyo';
let id = YoutubeService.getId(link);
expect(id).toBe('TFeSNOdNtyo');
});
});
我的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: ['jasmine'],
// list of files / patterns to load in the browser
files: [
'app/js/vendor.js',
'node_modules/angular-mocks/angular-mocks.js',
{ pattern: 'test-context.js', watched: false }
],
// 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-context.js': ['webpack']
},
webpack: {

loaders: [
{ test: /\.js/, exclude: /node_modules/, loader: 'babel-loader' }
]
},
watch: true
},
webpackServer: {
noInfo: true
},
// test results reporter to use

concurrency: Infinity
})
}
test-context.js
:
var context = require.context('./app/src', true, /\.spec\.js$/);
context.keys().forEach(context);
最后我找到了我做得不好的事情,只是将apis.spec.js
更改为:
import { YoutubeService } from './youtube.service.js';
let service;
describe('Youtube api service', () => {
beforeEach(angular.mock.module('app'));
beforeEach(() => {
service = new YoutubeService();
});
it('should get an ID from long youtube link', () => {
let link = 'https://www.youtube.com/watch?v=TFeSNOdNtyo';
let id = service.getId(link);
expect(id).toBe('TFeSNOdNtyo');
});
});
