Solution
If your database access is a separate module, you can mock out the module or parts of the module (e.g., the configuration part) using one of the following:
- sinon
- rewire
- horaa
- sandboxed-module

Problem
I am learning nodejs and I have a mongodb database with which i have to interact with. I am currently thinking of using mocha for a unit test framework and zombie.js for a acceptance test framework. I was wondering how could I do full scale acceptance tests which hit the mongodb database. Is there a framework/module that helps with replacing the database with a test database or does either mocha or zombie.js have functionality that can easily be used to replace the database. Also is there a framework that is similar to the idea of factories (instead of fixtures) in creating database objects. A similar concept that I have encountered in the rails world is in rspec, there is a spec_helper.rb file which runs before the tests are run which set the projects configuration to decide which database to hit when running tests. And it uses database_cleaner to clean out the test database before tests are run. For factories, i have used Factory girl to create factory objects from database schema again in the rails world.
