Spring - Autowired is null - Test - UnsatisfiedDependencyException: Error creating bean with name

Question

I'm trying to test my application, I've been trying to solve it for 3 days and I looked for stackoverflow and I still couldn't solve it. My problem is that Autowired is always null, and even though I import everything suggested as

@RunWith( SpringRunner.class )
@SpringBootTest
public class ESGControllerTest {
    @Autowired
    private ESGController esgController ;
    @Test
    public void deveRetornarSucesso_QuandoBuscarLatLong(){
        System.out.println(this.esgController);
    }

}

or

@RunWith( SpringJUnit4ClassRunner.class )
@ContextConfiguration
public class ESGControllerTest {
    @Autowired
    private ESGController esgController ;
    @Test
    public void deveRetornarSucesso_QuandoBuscarLatLong(){
        System.out.println(this.esgController);
    }

}

is always null and gives this error

EDIT: ESGController

    }

        return this.reverseGeocodeService.search(query);

     ....{

}

I edited and put the ESGController as code for more information.

Answer 1

Is ESGController decorated with @Controller or equivalent so that a bean of that class actually exist in the context?

Is the test class in the same package hierarchy as the rest of the application?

@SpringBootTest by default starts searching in the current package of the test class and then searches upwards through the package structure, looking for a class annotated with @SpringBootConfiguration from which it then reads the configuration to create an application context.
