title: Node JS test coverage issue with Istanbul
body: <p>I am running some node js unit tests using "Istanbul cover test.js", where test.js is the master test file which will call the actual scripts in our codebase. The problem is that the coverage report it generates is only on the test.js file and not on the actual lines of code in the codebase. Pardon me if this is a dumb question, but how do I get it to show coverage for the actual files that the tests refer to?</p>
