Spring Boot dependency for Testing is bringing exactly what I would have wished for (I hope they would include in the future the upcoming AssertJ).
The dependency looks like this:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency>
and brings in the classpath the usual Testing suspects: JUnit4, Mockito and Hamcrest.
