Welcome to this Course on Unit Testing with Spring Boot, JUnit 5, Mockito. We will create a basic Spring application and use JUnit to test it. Because you're presumably already familiar with writing and running unit tests for specific classes in your application, we'll focus on using Spring Test and Spring Boot to test the interactions between Spring and your code.

When it comes to building an enterprise-based application, Spring 5 is a popular web framework for back-end development among Java developers.

It is incredibly large because it is made up of several modules and projects.

The Spring Framework and Spring Boot enable developers to construct corporate Java applications that are high-performing, reusable, easily testable, and loosely coupled. Spring Boot is a tool for getting started very quickly with Spring applications. Spring Boot Focuses attention at a single point and Control a large collection of spring-* projects. Spring Boot allows a user to create stand-alone, production-grade Spring Applications and Exposes a lot of useful features by default.

It may be used to create any Java program.

Spring framework knowledge is in high demand in the enterprise market, and Spring framework developers are well compensated.

The fact that you have Spring Framework on your CV will set you apart from other Java developers.
