mongo-mock Build Status
This is an in-memory 'pretend' mongodb. The goal is to make the interface compatible with the real mongodb module so they are interchangeable.
There are a TON of features for mongo and I can't write them all myself- so pull requests are encouraged! My initial goal was to provide basic CRUD operations to enable this to work as a throw-something-together tool.
Maybe you don't want to (or can't) connect to a MongoDB instance for your tests?
Maybe you want to throw together a quick example app?
var mongodb = require('mongo-mock'); mongodb.max_delay = 0;//you can choose to NOT pretend to be async (default is 400ms) var MongoClient = mongodb.MongoClient; MongoClient.persist="mongo.js";//persist the data to disk // Connection URL var url = 'mongodb://localhost:27017/myproject'; // Use connect method to connect to the Server MongoClient.connect(url, {}, function(err, client) { var db = client.db(); // Get the documents collection var collection = db.collection('documents'); // Insert some documents var docs = [ {a : 1}, {a : 2}, {a : 3}]; collection.insertMany(docs, function(err, result) { console.log('inserted',result); collection.updateOne({ a : 2 }, { $set: { b : 1 } }, function(err, result) { console.log('updated',result); collection.findOne({a:2}, {b:1}, function(err, doc) { console.log('foundOne', doc); collection.removeOne({ a : 3 }, function(err, result) { console.log('removed',result); collection.find({}, {_id:-1}).toArray(function(err, docs) { console.log('found',docs); function cleanup(){ var state = collection.toJSON(); // Do whatever you want. It's just an Array of Objects. state.documents.push({a : 2}); // truncate state.documents.length = 0; // closing connection db.close(); } setTimeout(cleanup, 1000); }); }); }); }); }); });
Well, you know.. the usual:
$ npm install mongo-mock
