describe function not defined

[drexelapplab]

When I load the test.js within my terminal using node I recieve this:

describe('pdfFiller Tests', function(){
^

ReferenceError: describe is not defined

At first I thought it was a module issue (I had an earlier error with 'should'), however this is not the case. Could anyone give some insights towards this issue?
