How can I test REST APIs in Spring Boot?

You can test REST APIs in Spring Boot using tools like Postman, or by writing integration tests with Spring's testing framework.

What are some best practices for writing integration tests?

Some best practices include using @SpringBootTest, mocking external services, and keeping tests isolated and independent.

Can you show me an example of a test case?

Sure! Here's a simple example:

@Test
public void testGetUser() {
    ResponseEntity<User> response = restTemplate.getForEntity("/api/users/1", User.class);
    assertEquals(HttpStatus.OK, response.getStatusCode());
}

What dependencies do I need for testing?

You need dependencies like spring-boot-starter-test and possibly mockito for mocking objects.
