This document discusses testing Node.js applications. It recommends using the Mocha test framework along with the Chai assertion library and Supertest module. An example is provided showing how to test the Math.abs() function using Mocha, Chai, and expect assertions to validate results are equal to expected positive values regardless of input. A second example tests an HTTP server using the Supertest module.
