Explain Packages installed

  • cross-env - an operating system agnostic package for setting environment variables. We used it to set the NODE_ENV to test so that our test can use the test database. Run the command below to install cross-env.

npm i -D cross-env

  • Jest - Jest is a JavaScript testing framework developed by Facebook. It works out of the box with minimal configuration and has in-built test runner, assertion library and mocking support.

  • Supertest - A library for testing Node.js HTTP servers. It enables us to programmatically send HTTP requests such as GET, POST, PATCH, PUT, DELETE to HTTP servers and get results.

npm install --save-dev jest supertest
