Mockgo is a in-memory mocking engine for mongodb. In contrast to existing solutions mockgo does not try to imitate the mongodb interface by implementing its methods. Instead it uses the same approach Mockgoose uses and spins up a actual mongodb instance which holds the data in memory. That way the full feature set of mongodb can be used.
Works on all platforms which is due to the awesome mongodb-prebuilt package.
After spinning up the mongodb instance a connection to that instance is automatically created and returned.
npm install mockgo
Require mockgo, then retrieve a connection to the in-memory instance of mongodb by calling
An optional database name can be specified.
var mockgo =mockgo
You can retrieve connections to as many databases as you wish. They are internally cached.
var mockgo =mockgo
Methods and Properties
Returns a connection to a in-memory instance on mongodb.
databaseName is specified a dummy name will be used.
If a connection to the same database is requested multiple times a cached version of the same connection instance is returned.
The connection instance is a instance from the official native mongodb driver.
If you wish to use another version of the mongodb package you can easily override it by setting the
mongodb property before requiring a connection:
var mockgo =var mockgomongodb = //version xyzmockgo
Closes all existing mongodb connections and shuts down the mongodb instance.
Exposes the version of the official native mongodb driver, gives the possibility to override it.
Testing with Mocha
This is an example for a simple test with
mockgo in mocha.
