如何使用需要在节点中的规范业力茉莉花

Vague version question:

• 如何使用grunt在spec中使用require？

Context:

我正在研究一个尚未进行测试的现有节点项目，所以我读了一些并意识到要使用karma和jasmine .

我读了一些tutos（包括这些）：

• http://kwilson.me.uk/blog/use-karma-and-grunt-to-run-your-jasmine-tests-in-real-time/

• http://ahexamples.blogspot.com.br/2014/03/example-of-jasmine-karma-sonar-grunt.html

所以我试图用grunt运行我的规范并得到这个错误：

X遇到声明异常ReferenceError：找不到变量：require in file：///（...） - spec.js（第2行）（1）

这条线是这样的：

var myHelper = require(...);

但如果我使用via terminal“node-jasmine test”它就像魅力......

我的项目结构：

controller / helpers / models / node_modules / resources / test / test / spec / views / app.js Gruntfile.js package.json

在我的规范（内部测试/规范/）中，我使用了一个require（'../../ helpers / helper.js'），这对于node-jasmine来说没问题，但是对于grunt没有 .

节点 - 茉莉花测试：

.....完成0.015秒5次测试，5次断言，0次失败，0次跳过

咕噜：

运行“jasmine：pivotal”（jasmine）任务通过PhantomJS测试jasmine规范ReferenceError：找不到变量：require在app.js：1 Service Helper Tests X遇到声明异常ReferenceError：找不到变量：require in file ：///（...）/ test/spec/serviceHelper-spec.js（第2行）（1）1个规格在0.005s . 1次失败警告：任务“jasmine：pivotal”失败 . 使用--force继续 . 因警告而中止 .

我已将所有软件包安装到node_modules中（package.json中的依赖项中没有任何内容），我的Gruntfile.js是：

'use strict';

module.exports = function(grunt) {
    var $srcFiles = 'app.js';

    var $coverageOutputDir = $outputDir + '/coverage';


    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),

        // Jasmine test

                    keepRunner: 'true'  // keep SpecRunner/outfile file
                }
