Example 1: testing the web layer without authentication spring

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
public class SecuredControllerRestTemplateIntegrationTest {
 
    @Autowired
    private TestRestTemplate template;
 
    // ... other methods
 
    @Test
    public void givenAuthRequestOnPrivateService_shouldSucceedWith200() throws Exception {
        ResponseEntity result = template.withBasicAuth("spring", "secret")
          .getForEntity("/private/hello", String.class);
        assertEquals(HttpStatus.OK, result.getStatusCode());
    }
}

package com.example.restservice;

import java.util.concurrent.atomic.AtomicLong;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class GreetingController {

	private static final String template = "Hello, %s!";
	private final AtomicLong counter = new AtomicLong();

	@GetMapping("/greeting")
	public Greeting greeting(@RequestParam(value = "name", defaultValue = "World") String name) {
