As mentioned in spring documentation http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html you can use @ContextConfiguration with a special initializer:

ConfigFileApplicationContextInitializer is an ApplicationContextInitializer that can apply to your tests to load Spring Boot application.properties files. You can use this when you don’t need the full features provided by @SpringApplicationConfiguration.

In this example anyComponent is initialized and properties are injected, but run(args) methods won't be executed. (Application.class is my main spring entry point)

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = Application.class, 
                      initializers = ConfigFileApplicationContextInitializer.class)
public class ExtractorTest {
    @Autowired
    AnyComponent anyComponent;

    @Test
    public void testAnyComponent() {
       anyComponent.anyMethod(anyArgument);
    }
}
