What are some examples of integration testing in Spring Boot?

Integration testing in Spring Boot involves testing the application as a whole, including its interactions with external systems. Examples include testing REST APIs, database interactions, and message brokers.

Can you show me a simple example of an integration test for a REST API?

Sure! Here's a simple example using Spring Boot Test:

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

    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    public void testGetEndpoint() {
        ResponseEntity<String> response = restTemplate.getForEntity("/api/my-endpoint", String.class);
        assertEquals(HttpStatus.OK, response.getStatusCode());
    }
}

What dependencies do I need for integration testing in Spring Boot?

You typically need the following dependencies in your pom.xml:

• spring-boot-starter-test for testing support.
• spring-boot-starter-web if you're testing a web application.

How do I run my integration tests?

You can run your integration tests using Maven with the command mvn test, or directly from your IDE if it supports running JUnit tests.
