Rerequire
Dependency injection for Node.js modules. This module works the same as require but you can mock modules and globals.
var rerequire = require('rerequire');
rerequire(/* file to module you want to test */, /* module mocks */, /* global mocks */);Example
var test_file = rerequire('./test_files', {
'http': 'http mock', // Mock global module
'./mod': 'mock mod', // Mock local module
}, {
'Date': 'mock date', // Mock gloval
});
