About

The scope of this repository is to act as support for this Medium Story and to demonstrate a simple way of how to orchestrate docker containers and validate your application in simple steps using Node, a basic Express server, Axios to trigger requests and Jest to execute your tests.

Technology Stack

Prerequisites

• Node (latest stable v16.17.0)
• npm
• Docker

Scripts

$ npm install # will install all the dependencies on your machine

$ npm run start # will start the express server on your localhost

$ npm run test:local # will execute the tests against the server started on your localhost

$ npm run test:remote # will start two containers (one will boot the app - the other will execute the tests)
