modulemock

mock module requires for nodejs

What's it do?

• override what will be returned by a require call
• simplifies unit testing
• remove overrides (e.g. teardown)
• doesn't actually perform mocking functionality like spies etc, but allows you to set a mock in place of a module

Example

//call this first
var moduleMock = require('moduleMock')({
    'http': {
        get: function() {
            console.log('mocked!');
            return {on:function(){}};
        }
    }
});

var send = require('../lib/send.js');
send.get();

API

Create

var modulemock = require('modulemock');

Mock a module

modulemock({'http':{}});

Remove a fake module

modulemock.unmock('http');

Remove all fake modules

modulemock.unmockAll();

Clear module cache (only node_modules and yours, not in-builts)

modulemock.clearModuleCache();
