karma + jasmine单元测试显示define未定义

Question

我正在使用Karma和茉莉来编写我的单元测试。我将ES6代码转换为ES5以运行测试，但是当我运行测试时，我得到一个错误说：

Chrome 51.0.2704 (Windows 10 0.0.0) ERROR
Uncaught ReferenceError: define is not defined

我的 karma.conf.js 是这样的：

// Karma configuration
// Generated on Wed Jun 08 2016 07:12:07 GMT-0400 (Eastern Daylight Time)

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: ['jspm','jasmine'],

    // list of files / patterns to load in the browser
    files: [
        {pattern: 'lib/**/*.min.js', included: false},
        {pattern: 'js/Test/Dashboard/Unit/src/*.js', included: true},
        {pattern: 'js/Test/Dashboard/Unit/src/**/*.js', included: true},
        {pattern: 'js/Test/*Spec.js', included: true},
        {pattern: 'js/Test/**/*Spec.js', included: true}
    ],

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

    // 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_without_security'],

    customLaunchers: {
        chrome_without_security: {
            base: 'Chrome',
            flags: ['--disable-web-security']
        }
    },


    // 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
})
}

运行ES6-ES6的gulp任务是：

gulp.task('build:aurelia', function(){
gulp.src([paths.dashboardPathJs, '!' + paths.dashboardJs])
    .pipe(sourcemaps.init())
    .pipe(babel({ 
        presets: [ 'es2015-loose', 'stage-1'],
        plugins: [
            'syntax-flow',
            'transform-decorators-legacy',
            'transform-flow-strip-types',
            'transform-es2015-modules-amd'
        ] 
    }))
    .pipe(sourcemaps.write('./'))
    .pipe(gulp.dest('./js/Test/Dashboard/Unit/src'));
});

我完全迷失了为什么我得到的定义没有定义错误。提前谢谢。
