RestAssuredMockMvc - Autowire repositories are null - junit

Question

I'm testing a rest controller using RestAssuredMockMvc. This is my code
/*Repository*/
package com.rest.api.repository;
import java.util.List;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.querydsl.QueryDslPredicateExecutor;
import org.springframework.stereotype.Repository;
import com.mysema.query.types.Predicate;
#Repository
public interface ClientRepository extends JpaRepository<Client, Long>,
QueryDslPredicateExecutor<Client> {
Client findByClientId(Integer clientId);
Client findOne(Predicate predicate);
List<Client> findAll(Predicate predicate);
}
/*Services to be offered*/
package com.rest.api.service;
import java.util.List;
import com.mysema.query.types.Predicate;
import com.rest.api.model.Client;
import com.rest.api.repository.ClientRepository;
public interface ClientService {
Boolean saveEnterprise(Client client, ClientRepository clientRepository);
}
/*Implementation*/
package com.rest.api.service.implementations;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Service;
import com.google.common.collect.Lists;
import com.mysema.query.types.Predicate;
import com.rest.api.logging.LoggingManager;
import com.rest.api.model.Client;
import com.rest.api.repository.ClientRepository;
import com.rest.api.service.ClientService;
#Service
public class ClientImpl implements ClientService {
#Override
public Boolean saveEnterprise(Client client,
ClientRepository clientRepository) {
try {
LoggingManager.info(getClass(), "CLIENT="+client);
if(clientRepository == null){
LoggingManager.info(getClass(), "CLIENT REPO NULL");
}
if (client != null) {
clientRepository.save(client);
}
} catch (Exception e) {
LoggingManager.debug(getClass(),
"Error while saving assistance details");
e.printStackTrace();
return false;
}
return true;
}
}
/* CONTROLLER*/
#Controller
public class ClientController {
#Autowired
ClientRepository clientRepository;
#Inject
public void setRepository(ClientRepository clientRepository) {
this.clientRepository = clientRepository;
}
// Get Service Handle - A Singleton
private ClientService enterpriseServicehandle = EnterpriseClient
.getInstance().getEnterpriseService();
#RequestMapping(value = ApiEndpointConstants.CREATE_NEW_CLIENT, method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, headers = "content-type=application/x-www-form-urlencoded")
#ResponseBody
public EnterpriseResponse saveEnterprise(#RequestBody Client client) {
EnterpriseResponse enterpriseResponse = new EnterpriseResponse();
enterpriseServicehandle.saveEnterprise(client, clientRepository);
enterpriseResponse.setEnterprise(client);
enterpriseResponse
.setResponseCode(212);
enterpriseResponse
.setResponseMessage("Client creation Successful");
return enterpriseResponse;
}
}
/* Test Class*/
import static com.jayway.restassured.module.mockmvc.RestAssuredMockMvc.*;
import junit.framework.Assert;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.context.WebApplicationContext;
import com.jayway.restassured.http.ContentType;
import com.jayway.restassured.module.mockmvc.response.MockMvcResponse;
import com.rest.api.model.util.ResponseCodeConstants;
import com.rest.api.repository.AccesscodeRepository;
import com.rest.api.repository.ClientRepository;
public class ClientControllerTest {
#Autowired
private ClientRepository clientRepository;
#Autowired
private WebApplicationContext webApplicationContext;
#Autowired
private AccesscodeRepository accesscodeRepository;
#Before
public void setUp() throws Exception {
}
#After
public void tearDown() throws Exception {
}
#Test
public final void testFunctionality() {
String clientJson = "{\"name\":\"Client1\",\"clientId\":1000,\"fromEmailAddress\":\"goutham#atreya.in\"}";
MockMvcResponse clientCreationResponse = given()
.standaloneSetup(new ClientController())
.body(clientJson)
.contentType(ContentType.JSON)
.when()
.post("api/client/save")
.then()
.statusCode(200)
.extract().response();
System.out.println(clientCreationResponse.asString());
Integer clientResponseCode = clientCreationResponse.path("responseCode");
String clientResponseMessage = clientCreationResponse.path("responseMessage");
System.out.println("INT:" + clientResponseCode);
Assert.assertEquals(clientResponseCode, 211);
Assert.assertEquals(clientResponseMessage,"Client Creation Successful");
}
}
When I run the test case, I get this error (Note that, The clientRepository is NULL and throws a NPE, but the last line suggests that the client was successfully created.,

Can Anyone please guide me? What am I doing wrong? Why is my repository being null?
The endpoint does work, when Ii use Curl command and test, however, I'm unable to write a junit for unit testing, Please help

Answer 1

I meet exactly same problem.
When I run the project, it works fine.
But when I test controller some autowired variable becomes null, which failed the test.
In my code, I have a userWebController which does "signup" job. There is another class CustomedUserDetailsService which work with a JdbcTemplate object to add a new user to database. the JdbcTemplate object is autowired with a bean. When I test the controller, this JdbcTemplate object is null which means it is not injected successful.
I tried this following method(the jdbc bean is defined in class OnlineDBConfig), but does not work:
#ContextConfiguration( classes = {OnlineDBConfig.class})
I solve my problem with following solution:
1, move the failed_autowired object to the Test class (StandaloneUserControllerTest) directly.
2, pass the object to the controller class which use it.
Following is the final test class:
public class StandaloneUserControllerTest extends AbstractSpringJunit4Tests {
#Autowired
#Qualifier("jdbcOnline")
protected JdbcTemplate jdbc;
#Before
public void before(){
RestAssuredMockMvc.standaloneSetup(new UserWebController(jdbc) ) ;
if( jdbc == null )
fail("autowired failed again") ;
}
}
It is terrible, but it works.
Hope there will be better solution.
