Jasmine node testing child process.send

Question

I have a node.js application that has the main process main-process.js and the child process child-process.js . main-process.js looks like this:

 var childProcess = require('child_process'); var job = childProcess.spawn('node', ["child-process.js"], { detached = true, stdio: ['ipc'] }); 

My child-process.js performs some task and notifies the parent process of its status, uses

 exports.init = function() { //some processing here process.send({status: 'success or pending'}); } 

Now I want unit test child-process.js to use jasmine-node. But when I call the init() method from the specification, the jasmine-node throws an error saying

 TypeError: Object #<process> has no method 'send' 

Is there a way to mock the process variable? In other words, how to make unit test this script?
