An example node.js project, including tests with mocha, that behaves like a pocket calculator.

The project contains a simple node.js application that exposes REST APIs to perform arithmetic on integers, and provides a test suite with mocha and chai. The mocha-junit-reporters package is included to provide XML output that can be presented in a continuous integration tool like Azure DevOps.

To build, simply:

1. Runs npm install to install dependencies.
2. Runs npm test to run Mocha and execute the unit tests.
