What is the proper annotation since @SpringApplicationConfiguration, @WebIntegration, is deprecated in Spring Boot Framework?

Take a look into JavaDocs of deprecated classes:

* @deprecated as of 1.4 in favor of * {@link org.springframework.boot.test.context.SpringBootTest} with * {@code webEnvironment=RANDOM_PORT} or {@code webEnvironment=DEFINED_PORT}. */...@Deprecatedpublic @interface WebIntegrationTest {

* @deprecated as of 1.4 in favor of {@link SpringBootTest} or direct use of* {@link SpringBootContextLoader}.*/...@Deprecatedpublic @interface SpringApplicationConfiguration {

Is there also a replacement for TestRestTemplate()?

Yes, here it is:

 * @deprecated as of 1.4 in favor of * {@link org.springframework.boot.test.web.client.TestRestTemplate} */@Deprecatedpublic class TestRestTemplate extends RestTemplate {

A good place to start is now probably:Testing improvements in Spring Boot 1.4.

They describe a basic sample like the following:

@RunWith(SpringRunner.class)@SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT)public class MyTest {}

as a replacement to, one of many:

@RunWith(SpringJUnit4ClassRunner.class)@SpringApplicationConfiguration(MyApp.class)@WebIntegrationTestpublic class MyTest {}

you can use @EnableAutoConfiguration or @SpringBootApplication.

for testing purpose you can use @SpringBootTest(webEnvironment='your value') or simply @SpringBootTest

please refer :

http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

for testing the REST, you can use @RestClientTest and configure a RestTemplateBuilder.
