Spring boot unit test not work with application.yml

Question

I'm not able to make my unit test to read application.yml. I have followed the answer as the url below but it's still not working.

Spring Boot properties in 'application.yml' not loading from JUnit Test

Appreciate if somebody can help. Thanks.

My code as below:

Application.java

@SpringBootApplication
@ImportResource("classpath:app-config.xml")
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

TestTokenGenerator.java

    @RunWith(SpringJUnit4ClassRunner.class)
    @SpringApplicationConfiguration(classes=Application.class, initializers=ConfigFileApplicationContextInitializer.class)
    @ContextConfiguration(locations={"classpath:app-config-test.xml"})
    public class TestTokenGenerator {

        private static final Logger log = LoggerFactory.getLogger(TestTokenGenerator.class);

        @Value("${test}")
        private String testB;

        @Test
        public void testGenerate() throws UnrecoverableKeyException, KeyStoreException, NoSuchAlgorithmException, CertificateException, IOException{
            log.info(testB);
            log.info(tokenGenerator.generateToken());
}

application.yml

test: "123123"

See the comments for this issue https://github.com/spring-projects/spring-boot/issues/603, for example.

Declaring both @ContextConfiguration and @SpringApplicationConfiguration directly on a test class is not supported. The first instance of @ContextConfiguration that is discovered for a given test class (either on a class in the test class hierarchy or as a meta-annotation) will be used. All others will be ignored.
