was-it-used

Spy on 3rd party modules to tell if they were really used during testing

Example

Figure out which modules are used

var modules = ['./foo', './bar'].map(function (name) {
  return path.resolve(__dirname, name);
});
var wasIt = require('was-it-used');
wasIt(modules); // init
// use modules, even via another file that calls require('foo');
var foo = require('./foo');
foo();
var bar = require('./bar');
// bar is not used!
console.table(wasIt.used); // using console.table npm module
/*
key     value
------  -----
foo.js  true 
bar.js  false
*/

Implemented using really-need require wrapper.
