mongo-fake

Introduction

An ultra lightweight test fake implementation of mongo

What's a test fake? Check out this short blog.

Fakes the 2.x version of the standard Node Mongo Driver

Usage

Install the module and save as a dev dependency

npm install mongo-fake --save-dev

or

yarn add mongo-fake --dev

Import or require into your test code and use as you would the standard mongo driver (with limitations based on supported capabilities listed below)

import mongoFake from 'mongo-fake';


const someFunction = async () => {
  
  const mongoClient = mongo.MongoClient;
  const db = await mongoClient.connect()
  const collection = db.collection('aCollection');
  
  await collection.drop();
  await collection.insertMany([{a: 1}, {a: 2}, {a: 3, b: 4}]);
  const cursor = collection.find({});
  
  cursor.toArray().forEach((doc) => {
    
    // do something to the documents
  })
}

You can also take a look at the unit tests for more examples of usage.

Mongo Functionality Currently Faked

The following functionality has been faked, admittedly there isn't much yet. Pretty much just enough to support my own testing so far. I will continue to build out more support as I needed, feel free to contribute.
