Beginning API Development with Node.js

Exercise 22: Writing Basic Tests with Lab

In this exercise, we will introduce the concept of writing unit tests for the Hapi.js web API, mainly using the third-party lab module and the built-in assert module. Ideally, we should have a separate database for our tests, but for the sake of simplicity here, we will share our development database for tests too:

1. Let's first start by installing the necessary packages. Notice that we are using --save-dev since tests are not needed for production, therefore, they are development dependencies:

npm install lab --save-dev

Use the Code/Lesson-3/exercise-c for your reference.

2. Create a test folder at the root of the project—that is where we will have our tests. Since our API is a simple one, we will ...
