The document outlines the setup and testing of a Node.js microservice for managing movies, utilizing MongoDB for data storage. It includes example test scripts using the Tape framework to ensure proper connection and disconnection from the MongoDB database. Additionally, it provides an exercise for creating a calculator module and its corresponding unit tests.
