Testing the Fastify application
We are ready to implement the tests for our Fastify application. Before we start, we need to choose a framework that will help us write the code. Let’s complete this task first!
Installing the test framework
There are a lot of testing frameworks in the Node.js panorama. Some of them are highly opinionated, and others try to be agnostic. We are not going to discuss comparing the most famous modules. It is worth mentioning the ones most used by the community (in alphabetical order):

- Jest: https://www.npmjs.com/package/jest
- Mocha: https://www.npmjs.com/package/mocha
- node-tap: https://www.npmjs.com/package/tap
- Tape: https://www.npmjs.com/package/tape

- An easy-to-use and solid implementation
- Comprehensive assertions ...
