如何测试Spring MVC和存储库MongoDb

Question

import com.controller.ValidatorClass;
import com.model.Entity;
import com.model.Status;
import com.repository.Repository;

@Service
public class Service {

    @Autowired
    private Repository repository;
    
    @Autowired
    private SequenceGeneratorService service;
    
    public ResponseEntity storeInDb(ExecutorEntity model) {
        ValidatorClass validation = new ValidatorClass();
        Map<String, String> objValidate = validation.getInput(model.getLink(), model.getUsername(), 
                model.getPassword(), model.getSolution());
        model.setId(service.getSequenceNumber(Entity.SEQUENCE_NAME));
        model.setStatus(Status.READY);
        repository.save(model);
        return new ResponseEntity(model, HttpStatus.OK);
    }
    
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(MethodArgumentNotValidException.class)
    public List<String> handleValidationExceptions(MethodArgumentNotValidException ex) {
        return ex.getBindingResult()
            .getAllErrors().stream()
            .map(ObjectError::getDefaultMessage)
            .collect(Collectors.toList());
    }
}

@RestController
@RequestMapping(value = "/create")
public class Controller {

    @Autowired
    private Service service;

    @RequestMapping(value = "/create", method = RequestMethod.POST)
    public ResponseEntity code(@Valid @RequestBody Entity model) {
        return service.storeInDb(model);
    }

@Transient  
    public static final String SEQUENCE_NAME = "user_sequence";

    @NotNull(message = "Name can not be Null")
    private String username;

    @NotNull(message = "Password can not be Null")
    private String password;

    @NotNull(message = "Jenkins Link can not be Null")
    private String Link;

    @NotNull(message = "Solution can not be Null")
    private String solution;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;

    private Status status; //enum class having READY and FAIL as values.

JUnit是一个广泛的主题，您应该了解它:https://JUnit.org/junit5/

请注意，JUnit5是当前版本（我看到您已经用JUnit4标记了您的问题）。

我将给您一个如何编写集成测试的想法，以帮助您开始编写集成测试。在通往智慧的旅程中，您可能会遇到TestrestTemplate，但现在建议使用WebTestClient。

package no.yourcompany.yourapp.somepackage;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.reactive.AutoConfigureWebTestClient;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.ResponseEntity;
import org.springframework.test.web.reactive.server.WebTestClient;

import static org.assertj.core.api.AssertionsForClassTypes.assertThat;

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureWebTestClient
public class ExecutorControllerTest {

    @Autowired
    WebTestClient webTestClient;

    @Test
    public void postExecutor_validModel_receiveOk() {
        webTestClient
                .post().uri("/executor")
                .bodyValue(createValidExecutorEntity())
                .exchange()
                .expectStatus().isOk();
    }

    @Test
    public void postExecutor_validModel_receiveResponseEntity() {
        webTestClient
                .post().uri("/executor")
                .bodyValue(createValidExecutorEntity())
                .exchange()
                .expectBody(ResponseEntity.class)
                .value(responseEntity -> assertThat(responseEntity).isNotNull());
    }

    private static ExecutorEntity createValidExecutorEntity() {
        ....
    }
}
