Mongodb and Jest Testing

How to test code that uses mongodb as storage.

Description

I have created a UserService class which interacts with mongodb for creating, retrieving, updating and deleting resources in users collection. So in this repository explore different ways of testing the functionality of that service.

Development

Prerequisites

• yarn or npm installed.
• Latest nodejs installed.
• Docker installed.

Run

In order to run tests locally you need

• Run yarn or npm install for installing dependencies
• Execute tests
  • For mocks yarn test:mock or npm run test:mock
  • For docker yarn test:docker or npm run test:docker
  • For mongodb-memory-server yarn test:memory or npm run test:memory

Useful commands

• Run jest in watch mode yarn test:mock --watchAll, useful for when writing tests.
• Run docker compose from root folder docker-compose -f ./docker-method/docker-compose.yaml <command> <flags>
