Error with MockMVC and Spring boot integration test

I am trying to create an integration Test for my Spring boot App. For this, I followed the following tutorial: https://programandoenjava.com/pruebas-de-integracion-en-spring-boot/

This is my code:

@SpringBootTest(classes = ArticulosControllerImpl.class)
@AutoConfigureMockMvc
public class ArticulosControllerIT {
    @Autowired
    private MockMvc mockMvc;
    private final String ARTICULOS_BASE_URL = "/articulos";

    @Test
    public void CUANDO_se_llama_a_articulos_ENTONCES_el_estado_es_200() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.get(ARTICULOS_BASE_URL))
                .andExpect(status().isOk())
                .andExpect(MockMvcResultMatchers
                        .content()
                        .contentTypeCompatibleWith(MediaType.APPLICATION_JSON));
    }
}

But when executing my test I get the following error. I guess it's because in my controller I am using an ArticulosService bean but I don't know how to fix it and in that same service I'm using other beans. Any solutions please?

Description:

Parameter 0 of constructor in com.ulises.mybartpv.articulos.rest.controllers.impl.ArticulosControllerImpl required a bean of type 'com.ulises.mybartpv.articulos.services.ArticulosService' that could not be found.


Action:

Consider defining a bean of type 'com.ulises.mybartpv.articulos.services.ArticulosService' in your configuration.

Thanks

Solution

I decided to change the approach by using TestRestTemplate as follows:

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class ArticulosControllerIT {
    @LocalServerPort
    private int port;
    @Autowired
    private TestRestTemplate restTemplate;
    @Autowired
    private ArticulosService articulosService;
    @Autowired
    private ModelMapper modelMapper;
    @Autowired
    private ArticuloRepository articuloRepository;
    private final String ARTICULOS_BASE_URL = "/articulos";
    private String host;
    private HttpHeaders headers;
    private final ObjectMapper objectMapper = new ObjectMapper();


    @BeforeEach
    void setUp() {
        host = "http://localhost:" + port;
        headers = new HttpHeaders();
    }

    @Test
    void CUANDO_se_llama_a_articulos_ENTONCES_el_estado_es_200() throws Exception {
        HttpEntity<Void> entity = new HttpEntity<>(null, headers);
        ResponseEntity<GetArticulosResponse> response = restTemplate.exchange(host + ARTICULOS_BASE_URL, HttpMethod.GET, entity, new ParameterizedTypeReference<>() {});
        List<ArticuloDTO> articulos = Objects.requireNonNull(response.getBody()).getArticulos();
    }
}
