Spring Boot provides two modules for test support—sprint-boot-test and spring-boot-test-autoconfigure. spring-boot-test contains core items, and spring-boot-test-autoconfigure supports auto-configuration for tests. These modules have a number of utilities and annotations to help when testing your application. It is very simple to add these modules in the Spring Boot application by adding the spring-boot-starter-test starter dependency in your Maven file. This starter imports both Spring Boot test modules as well as JUnit, AssertJ, Hamcrest, and a number of other useful libraries. Let's see the following Maven dependency to include test support in the Spring Boot application:
<dependency> <groupId>org.springframework.boot</groupId> ...
