Difference between @ContextConfiguration and @SpringApplicationConfiguration in Spring Boot Testing?

Even though both @ContextConfiguration and @SpringApplicationConfiguration annotations are used along with SpringJUnit4ClassRunner to specify how to load the Spring application context, there is a subtle difference between them. Although @ContextConfiguration does a great job in loading application context it doesn't take full advantage of Spring Boot features. Spring Boot applications are ultimately loaded by either SpringApplication ( in case of the JAR) or SpringBootServletInitializer. This class not only loads the application context but also enables logging and loading of external properties specified in application.properties or application.yml file, and other features of the Spring Boot framework, which is not loaded or enabled by the @ContextConfiguration annotation.
