In this section, we will have a brief look at writing unit tests for Hapi.js APIs. Testing is a huge topic that perhaps requires a whole course on its own, but in this section, we will be introducing the essential parts to get you up and running.
Let's first underscore the importance of writing unit tests for your API:
- Maintainability: This is what I consider as the most important value of adding tests to your software. When you have tests, you can be confident to come back months later and, modify your code without worrying whether you broke anything by your update.
