I developed a component in a library with sprin libraries. My component is as follows:

@Component
@RequestScope
public class RequestInfoComponent {
   @Autowired
   private HttpServletRequest reques;

   ...
}

The needed dependencies are as follows:

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-core</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
</dependency>

Now I want to write some test case. I add spring-boot-starter-test dependency. Now I want to mock HttpServletRequest.getHeader('Authorization') in a @SpringBootTest test case. I want to know How define test services?

I developed a spring component and I want to write unit test for it.
