Webstorm,nodejs, npm test, '.' is not recognized as an internal or external command,

I'm new to nodejs, working on Webstorm 9.0.1, i'm trying to use Lab module for tests using this tutorial http://ift.tt/1o2pauV

My package.json file contains the following :

{ "name": "test", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "test": "./node_modules/lab/bin/lab -c" }, "author": "", "license": "ISC", "devDependencies": { "hapi": "^8.0.0", "joi": "^5.0.2", "lab": "^5.1.0" } }

The local node_modules directory is created in the directory C:\Users\DT002\WebstormProjects\hapiB\test>

the problem is that when i try to test, i got the following error :

C:\Users\DT002\WebstormProjects\hapiB\test>npm test

test@1.0.0 test C:\Users\DT002\WebstormProjects\hapiB\test ./node_modules/lab/bin/lab -c

'.' is not recognized as an internal or external command, operable program or batch file. npm ERR! Test failed. See above for more details. npm ERR! not ok code 0

Thank you for any suggestions.
