mongoose-fresh-db

Create a connection to a brand new MongoDB Database before each test.

How it works

This pacakge exports two functions:

createNewDatabase

Creates a new mongoose connection to mongodb://localhost/test_database_${randomnumber}. This function is supposed to be run before every test which is using the databse.

This ensure a few things:

• Every test is run in complete isolation
• Test can be run in parralel
• No need to reset the db after each test as every test starts with a clean db.

dropDatabase

Drops the database from the default mongoose connection. Supposed to be run after each test.

Installation

npm install --save-dev mongoose-fresh-db

Usage

Currently only tested with jest.

This package assumes that the tested code itself doesn't create a mongoose connection!

import { createNewDatabase, dropDatabase } from 'mongoose-fresh-db';

beforeEach(createNewDatabase);
afterEach(dropDatabase);

test('this test will have a shiny new db instance', () => {});
