Spring Boot Testing Basics: How to Unit Test & Integration Test REST Controllers

In this tutorial, I want to discuss some basics of testing a rest controller in a Spring Boot application. This came up because of a tweet I sent out recently asking developers to stop calling a certain test a unit test. The reason I said this is because whenever you start involving Spring and the whole request & response lifecycle its no longer a unit test. In this demo, I will create a new Spring Boot application, create a simple rest controller and then show you how I would Unit & Integration test that controller. If anything this is just meant to spark a discussion so I would love to hear your thoughts on the subject. When you have completed this tutorial you should understand: ✅ Create a new Spring Boot Application ✅ Create a new Spring Boot Rest Controller ✅ Create a Unit Test ✅ Create an Integration Test ✅ Run a basic test in a Spring Boot Application ✅ How to use JUnit 5 in a Spring Boot Integration Test 🔗Resources & Links mentioned in this video: Source Code: https://github.com/danvega/unit-vs-int Martin Fowler Unit Test: https://martinfowler.com/bliki/UnitTest.html 👋🏻Connect with me: Website: https://www.danvega.dev Twitter: https://twitter.com/therealdanvega Github: https://github.com/danvega Instagram: https://www.instagram.com/thedanvega LinkedIn: https://www.linkedin.com/in/danvega Coffee & Code: https://www.danvega/dev/newsletter SUBSCRIBE TO MY CHANNEL: http://bit.ly/2re4GH0 ❤️
