不能在我的mocha测试中使用需求通过gulp与karma runner

Question

我的第二个项目又遇到了同样的问题。可悲的是，我必须在这里发布大部分配置文件，以向您显示足够的信息 - 所以不要害怕;）

我正在使用以下单元测试：

gulpfile.js

// including plugins
var gulp = require('gulp')
    , uglify = require("gulp-uglify")
    , concat = require('gulp-concat')
    , clean = require('gulp-clean')
    , open = require('gulp-open')
    , babel = require("gulp-babel")
    , copy = require("gulp-copy")
    , mocha = require('gulp-mocha');

var Server = require('karma').Server;


gulp.task('tests', function(done) {
    Server.start({
        configFile: __dirname + '/karma.config.js',
        singleRun: true
    }, function() {
        done();
    });
});

karma.config.js

module.exports = function(config) {
    config.set({
        browsers: ['Chrome'],
        frameworks: ['mocha'],
        files: [
            './target/src/heritage.guard.js',
            './tests/dummies/dummies.babel.js',
            './tests/heritageguardtests.js'
        ],

        plugins:[
            'karma-chrome-launcher',
            'karma-mocha'
        ]
    });
};

heritageguardtest.js

var assert = require('assert');

var classDummy = new ClassDummy();
var superClassDummy = new SuperClassDummy();

describe('HeritageGuard Tests', function () {
    describe('getSuperClassName', function () {
        it('should return the name of the super class as String', function () {

            var superClassName = HeritageGuard.getSuperClassName(classDummy);
            assert.equal(superClassName, "SuperClassDummy");
        });
    });
});

输出Gulp“测试”任务

正如你所知，require没有定义但没有使用var assert = require（'assert'）;在我的mocha测试文件中我不能使用断言库==无法测试。

那么以前有人怎么解决这个问题呢？我找不到任何解决方案，无论是使用另一种方式来使断言库工作（没有require），也没有要求在testfile中工作。
