我正在尝试为基于 AngularJS 的 JavaScript 插件设置单元测试。该插件通过 Gulp 与 Browserify 捆绑在一起。它取决于从文件夹中注入wiredep和gulp-inject从bower_components文件夹中注入的外部库。这一切在生成的包中运行良好，但如果我尝试通过 gulp 运行 Karma 单元测试，我会收到以下错误：

未捕获的类型错误：angular.module 不是 /tmp/94dbea5947f4758ab1ee6935e2f4b3f1.browserify:365 <- app/js/services/index.js:9:0 处的函数

在这个文件中，angular加载了var angular = require('angular');，并且 aconsole.log(angular)给出了一个空对象。

我的karma.conf.js：

'use strict';

const istanbul = require('browserify-istanbul');
const isparta = require('isparta');
const mainBowerFiles = require('main-bower-files');

const karmaBaseConfig = {

    basePath: '../',

    frameworks: ['jasmine', 'browserify'],

    preprocessors: {
        'app/js/**/*.js': ['browserify', 'coverage'],
        '**/*.html': ['ng-html2js']
    },

    browserify: {
        debug: true,
        extensions: ['.js'],
        transform: [
            [["babelify", {"ignore": "/\/bower_components\//"}]],
            'browserify-ngannotate',
            'bulkify',
            'debowerify',
            'brfs',
            istanbul({
                instrumenter: isparta,
                ignore: ['**/bower_components/**', '**/node_modules/**', '**/test/**']
            })
        ]
    },

    ngHtml2JsPreprocessor: {
        stripPrefix: 'app/',
        moduleName: 'templates'
    },

    plugins: [
        'karma-jasmine',
        'karma-coverage',
        'karma-browserify',
        'karma-ng-html2js-preprocessor',
        'karma-chrome-launcher'
    ],

    files: mainBowerFiles({
        filter: '**/*.js',
        paths: {
            bowerDirectory: 'bower_components',
            bowerrc: '.bowerrc',
            bowerJson: 'bower.json'
        }
    }).concat([
        // app-specific code
        'app/js/main.js',

        // 3rd-party resources
        'node_modules/angular-mocks/angular-mocks.js',

        // test files
        'test/unit/**/*.js'
    ]),

    exclude: [],

    reporters: ['progress', 'coverage'],

    port: 9876,

    colors: true,

    autoWatch: false,

    browsers: ['Chrome'],

    singleRun: true
};

const customLaunchers = {
    chrome: {
        base: 'SauceLabs',
        browserName: 'chrome'
    }
};

const ciAdditions = {
    sauceLabs: {
        testName: 'Karma Unit Tests',
        startConnect: false,
        build: process.env.TRAVIS_BUILD_NUMBER,
        tunnelIdentifier: process.env.TRAVIS_JOB_NUMBER
    },
    browsers: Object.keys(customLaunchers),
    customLaunchers: customLaunchers,
    reporters: ['progress', 'coverage', 'saucelabs']
};

module.exports = function (config) {
    const isCI = process.env.CI;
    config.set(isCI ? Object.assign(karmaBaseConfig, ciAdditions) : karmaBaseConfig);
};

所有主要的应用程序文件都位于以下app/，bower 文件bower_components/，节点模块node_modules/和测试规范test/unit/。

它基于这个样板：https ://github.com/jakemmarsh/angularjs-gulp-browserify-boilerplate 。

错误发生在 Karma 启动 Chrome 之后，但在执行任何单元测试之前（我console.log在单元测试中检查过）。

任何帮助将不胜感激。

终于解决了。

unit.js（吞咽单元任务）：

'use strict';

import config   from '../config';
import path     from 'path';
import gulp     from 'gulp';
import {Server} from 'karma';

gulp.task('unit', ['copy-bower-components',
    'styles',
    'images',
    'fonts',
    'api',
    'views',
    'browserify',
    'inject'
], function (done) {

    new Server({
        configFile: path.resolve(__dirname, '../..', config.test.karma),
        singleRun: true
    }, function (exitCode) {
        console.log('Karma has exited with ' + exitCode);
        done();
    }).start();

});

这里的关键是在单元测试开始之前运行 browserify。karma.conf.js：
