This course presents a way to start with Unit Tests in Java. The examples that I’m providing are inside a Spring Boot App. I think this adds value for you when it comes to getting a clearer picture of Unit Tests in an actual environment that is used by thousands if not millions of apps.

I think that it’s important for you to understand that these are my opinions when it comes to unit testing. I’m sure that there are many advice out there which are better than mine. What I’m trying to present here is how I see the Unit Tests after a couple of years of professional experience with them. I try to discuss about different topics that I learned about in the most basic ways.
