@tim-code/jest-config-server v0.3.2

jest-config-server

npm install @tim-code/jest-config-server

A companion library to server, this allows the server to be run as part of Jest tests.

Usage

Usage in including project:

// jest.config.js
import config from "@tim-code/jest-config-server"

export default {
  ...config,
}

Example test command in package.json:

"test": "ROUTES_DIR=backend node --no-warnings --experimental-vm-modules node_modules/.bin/jest",

Environment Variables

PORT: the port to use for the test server; Node randomly assigns an available one by default or if PORT is 0

By using a random port, multiple test suites can run in parallel and there is no worry about asking for a port that is already in use.

ROUTES_DIR: the directory to provide to the server during global setup

Additionally:

process.env.PORT is set after the server has been started to the port used to start the server.
