I was also going through this annoying problem while running my test cases, so I tried many ways to get across it. But the way works for me is to run your test runner from the directory which contains your main file which includes your nodejs spawn function something like this:

nodeProcess = spawn('node',params, {cwd: '../../node/', detached: true });

For example, this file name is test.js, so just move to the folder which contains it. In my case, it is test folder like this:

cd root/test/

then from run your test runner in my case its mocha so it will be like this:

mocha test.js

I have wasted my more than one day to figure it out. Enjoy!!
