The PhantomJS API claims to allow access to 'fs' and a few other built-in commonJS modules through the standard require interface. grunt-contrib-jasmine claims to run all specs using phantomJS. But when I use grunt-contrib-jasmine the require method doesn't seem to be available?
fs = require('fs')
describe 'DesignService', ->
it 'test loadFromJSON', ->
jsonFile = fs.read("resources/sample_pole.json")
Gives me the error:
ReferenceError: Can't find variable: require at
>> target/spec/Spec.js:3
What am I doing wrong?
In case it isn't clear, I am compiling from coffeescript, and then pointing the grunt-contrib-jasmine to the output of the compilation. The other specs are all running fine.

require method is only available on server side (Nodejs/PhantomJS), but all jasmine tests (specs) are executed on the client side.
You could create a JavaScript file in helpers folder with the content like this:
window.jsonFile = { some : json_object }
And use a jsonFile reference in your spec files.
From the PhantomJS description:
PhantomJS is a headless WebKit scriptable with a JavaScript API.
From grunt-contrib-jasmine description:
Run jasmine specs headlessly through PhantomJS.
grunt-contrib-jasmine is automatically creating _SpecRunner.html file (see below for example) with all user specs and passing it to the PhantomJS. PhantomJS is a separate executable, that in Nodejs is only wrapped as a package. This is the same executable as if downloaded from Phantomjs.org page.
In the end this line is executed: .\node_modules\grunt-contrib-jasmine\node_modules\grunt-lib-phantomjs\node_modules\phantomjs\lib\phantom\phantomjs .\node_modules\grunt-contrib-jasmine\node_modules\grunt-lib-phantomjs\phantomjs\main.js .\_SpecRunner.html.
Here main.js file is to open the page and bind alerts (alert(jsonString)) that are thrown to the grunt logging.
So PhantomJS API is available in main.js, but not in _SpecRunner.html and jasmine spec files.
The result is the same as if opened _SpecRunner.html with the browser, except all messages will be intercepted by jasmine reporter and displayed on screen.
