问题描述

我正在尝试在AngularJS中使用Karma，Jasmine，Webpack进行测试.我的webpack运行正常，可以使用npm start

I am trying to setup testing with Karma, Jasmine, Webpack in AngularJS.My webpack is working fine and I can run my website using npm start

一个简单的测试可以正常工作，但是当我尝试添加app.js时，一切都变得艰难了.

A simple test works fine but the moment I try to add my app.js everything goes downhill.

我尝试了许多搜索和解决方案.请不要以为，当我陷入困境时，我正在写这个问题.我今天整天都在搜寻，并找到可能的解决方案.

I have tried many many many searches and many solutions. Please dont think, I am writing this question the moment I hit a deadend. I have spent all day today just googling and find possible solutions.

有我的karma.conf.js文件

There is my karma.conf.js file

// Karma configuration
// Generated on Mon Sep 18 2017 09:27:36 GMT+1000 (AEST)

var webpackConfig = require('./webpack.config.js');


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

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

    frameworks: ['jasmine'],

    // ... normal karma configuration
    files: [
        './node_modules/jasmine-core/lib/jasmine-core/jasmine.js',
        './node_modules/angular/angular.js',                                        // angular
        './node_modules/angular-mocks/angular-mocks.js',                            // loads our modules for tests

        // all files for test
        './resources/assets/js/auth/app.js',
        './resources/assets/js/account/invoices/*.spec.js',
    ],

    preprocessors: {
        // add webpack as preprocessor
        './resources/assets/js/account/invoices/*.spec.js':     ['webpack'],
    },

    webpack: {
        // webpack configuration
        webpackConfig
    },

    webpackMiddleware: {
      // webpack-dev-middleware configuration
      // i. e.
      stats: 'errors-only'
    },

    // 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_DEBUG,

    // 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
  })
}

我写的测试是

describe('Unit testing Dash', function() {
    var $compile,
        $rootScope;

    // Load the myApp module, which contains the directive
    beforeEach(angular.mock.module('app'));

    // Store references to $rootScope and $compile
    // so they are available to all tests in this describe block
    beforeEach(inject(function(_$compile_, _$rootScope_){
        // The injector unwraps the underscores (_) from around the parameter names when matching
        $compile = _$compile_;
        $rootScope = _$rootScope_;
    }));

    it('Replaces the element with the appropriate content', function() {
        // Compile a piece of HTML containing the directive
        var element = $compile("<dash-list></dash-list>")($rootScope);
        // fire all the watches, so the scope expression {{1 + 1}} will be evaluated
        $rootScope.$digest();
        // Check that the compiled element contains the templated content
        expect(element.html()).toContain("Unpaid");
    });
});

它失败并显示此错误:

18 09 2017 15:00:18.554:DEBUG [web-server]: serving (cached): project/resources/assets/js/account/invoices/dash.spec.js
18 09 2017 15:00:18.557:DEBUG [web-server]: serving (cached): project/resources/assets/js/account/invoices/add-business.spec.js
18 09 2017 15:00:18.576:DEBUG [web-server]: serving: project/node_modules/karma/static/context.js
Chrome 60.0.3112 (Mac OS X 10.12.6) ERROR
  Uncaught SyntaxError: Unexpected token import
  at resources/assets/js/auth/app.js:1

我正在使用OSX.从技术上讲，webpack应该将编译后的文件提供给Karma.但是意外的令牌 import 意味着该文件没有被编译并提供给Karma.

I am using OSX. Technically, webpack should serve the compiled file to Karma. But unexpected token import means that file is not being compiled and served to Karma.

请帮助.

我什至尝试使用babel进行编译，但这也没有任何进展.我搬到webpack的原因是我们已经建立了webpack config，并且使用webpage.config

更新

对于研究这个问题的人，我使用了Felix的OPTION#1.我只是在Karma中包含了已编译的文件.它像魅力一样工作.

To anyone who stubble upon this question, I used the OPTION #1 by Felix.I just included the compiled files in the Karma. It worked like charm.

只要文件更改，Webpack就会自动编译文件，因此只需添加输出即可正常工作.

Webpack auto compile files whenever files are changed, so just adding the output worked fine.

我的文件数组如下

files: [
    './node_modules/jasmine-core/lib/jasmine-core/jasmine.js',
    './node_modules/angular/angular.js',                                        // angular
    './node_modules/angular-mocks/angular-mocks.js',                            // loads our modules for tests
    './resources/assets/js/account/stripe.spec.js',
    './node_modules/angular-stripe/index.js',
    './node_modules/angular-stripe-checkout/angular-stripe-checkout.js',

    // all files for test
    './public/assets/vendor.bundle.js',
    'http://localhost:8080/assets/account.js',
    './resources/assets/js/account/invoices/*.spec.js',

不幸的是，我不得不在第二个选项中使用http，但是它工作正常.
