To enable testing, add the following dependency in the pom.xml file:

<dependency> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-test</artifactId> 
</dependency>

• The RestaurantControllerIntegrationTests class, which uses the@SpringApplicationConfiguration annotation to pick the same configuration that Spring Boot uses:

@RunWith(SpringJUnit4ClassRunner.class)
