Learn How to Use JUnit 5 to Test Your Spring Boot Apps

Every good developer knows not to push code live without appropriate test coverage. Adding a series of tests builds confidence that your application is equipped to handle anything. When creating your tests, it’s crucial to use a modern and comprehensive set of tools. A modern framework assures that you can keep up with the updates within your language and libraries. A comprehensive set of tools assures that you can efficiently test all areas of your application without having to write your own test utilities. Luckily for Java developers, JUnit 5 handles both requirements.

Today, I’ll walk you through how to test your Spring Boot application with JUnit 5. For this post, you'll build a Spring Boot app with a basic REST API, that will calculate a few things about a person’s birthday. We’ll use OAuth 2.0 and Okta to secure the REST API. After we create the REST API, I’ll walk you through unit testing the code with JUnit 5.
