In a Spring boot test, how can I create a bean and injects by @Autowired?

When I test my Spring boot service I don't know how I can inject an @Autowired bean.

My bean (Spring fills @Value from application.yml):

@Component
public class NavigatorProperties
@Value("$timerDelay")
private String timerDelay;

public String getTimerDelay()
return timerDelay;

public void setTimerDelay(String timerDelay)
this.timerDelay = timerDelay;




My api:

public class ListenerApi implements IRestListenerApi
@Autowired
private NavigatorProperties np;

public String doSomething (...) // This is my service method.
// Here np.getTimerDelay() will return application.yml value.
int timerDelay = Integer.decode(np.getTimerDelay());
...




This works fine and int value is correct. Here is my test:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = ListenerApiTest.class, NavigatorProperties.class)
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class ListenerApiTest {
@Autowired
private NavigatorProperties np; // Can be autowired or a new Object.

// Object to test.
private ListenerApi listenerApi;

@Test
public void test01ForceNumberFormatException()
np.setTimerDelay("NumberFormatException");
// Inyect into ListenerApi


@Test
public void test02ForceNullPointerException()
np.setTimerDelay(null);
// Inyect into ListenerApi



In this test comments, how I can inyect into ListenerApi by @Autowired?

Thanks.

@Autowired

First of all, you need to annotate your dependency with org.springframework.stereotype.Component.

org.springframework.stereotype.Component

@Component
public class ListenerApi implements IRestListenerApi {


Then Inject it in wherever required :

@Autowired
private ListenerApi listenerApi;


Add component scan annotation with the package to scan

@ComponentScan(basePackages = "my.package.to.scan")


your @SpringBootTest should be like:

@SpringBootTest(classes = ListenerApi.class, NavigatorProperties.class)


include every bean class that you want to inject into ListenerApiTest
