I have 2 DataSources in my app.
So, to get the required JdbcTemplate, i use #Qualifier. But, when i do like below, the test runs... but stays waiting indefinitely, if there is any use of JdbcTemplate in the "Method Under Test".
#Service
#Transactional
public class SampleDatabaseService {
#Autowired
#Qualifier("firstDbJdbcTemplate")
private JdbcTemplate firstDbJdbcTemplate;
#Autowired
#Qualifier("secondDbJdbcTemplate")
private JdbcTemplate secondDbJdbcTemplate;
#Cacheable("status")
public Map<String, Device> readAllValidDeviceStatus() {
Map<String, Device> allDeviceStatuses = new HashMap<>();
//Stops at below line indefinitely if "SpyBean" is used
List<StatusDetail> statusDetails = firstDbJdbcTemplate
.query(SqlQueries.READ_DEVICE_STATUS, BeanPropertyRowMapper.newInstance(StatusDetail.class));
statusDetails
.stream()
.filter(deviceStatus -> deviceStatus.getName() != "Some Invalid Name")
.forEach(deviceStatus -> allDeviceStatuses
.put(deviceStatus.getName(), buildDevice(deviceStatus)));
return allDeviceStatuses;
}
/** More Stuff **/
}
and the Test :
#RunWith(SpringRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
#Transactional
#Rollback
#ActiveProfiles("test")
public class SampleDatabaseServiceTest {
#SpyBean
#Qualifier("firstDbJdbcTemplate")
private JdbcTemplate firstDbJdbcTemplate;
#Autowired
private SampleDatabaseService serviceUnderTest;
#Before
public void populateTables() {
//Insert some Dummy Records in "InMemory HSQL DB" using firstDbJdbcTemplate
}
#Test
public void testReadAllValidDeviceStatus() {
// When
Map<String, Device> allDeviceStatuses = serviceUnderTest.readAllValidDeviceStatus();
// Then
assertThat(allDeviceStatuses).isNotNull().isNotEmpty();
// More checks
}
/* More Tests */
}
But, when i replace the #SpyBean with #Autowired in Test, it works fine.
Why is it so? Any help is greatly appreciated. :)
Use it in below format
#MockBean(name = "firstDbJdbcTemplate")
private JdbcTemplate firstDbJdbcTemplate;

Hi I am trying to write unit test for Auditing
#DataJpaTest
#EnableJpaAuditing
#RunWith(SpringRunner.class)
#AutoConfigureEmbeddedDatabase(type=POSTGRES)
public class MyTestAuditor {
#Autowired
private TestEntityManager entityManager;
#Test
public void auditTest() throws InterruptedException {
final MyEntity testEntity = MyEntity.builder()
....
.build();
SLOEntity entity = entityManager.persistAndFlush(testEntity);
assertNotNull(testEntity.getCreatedOn());
assertNotNull(testEntity.getLastModifiedOn());
assertNotNull(testEntity.getCreatedBy());
assertNotNull(testEntity.getLastModifiedBy());
}
}
I pass first two assertion, the timestamp ones, but fail the username part. Is there anything I am missing here, thanks:)
I am trying to write the Junit test cases for the below hazelcast Jet Pipeline.
My component:
#Component
public class UserJetJob extends AbstarctJetJob {
private static final String TABLE_NAME = "User";
#Autowired
private ClientConfig clientConfig;
#Value("${jdbc.connection_url}")
private String connectionUrl;
#Override
public Pipeline buildPipeline() {
Pipeline p = Pipeline.create();
p.readFrom(Sources.jdbc(connectionUrl,
"SELECT * FROM " + TABLE_NAME,
UserJetJob::buildUser))
.map(a -> Util.entry(a.getId(), a))
.writeTo(Sinks.remoteMap("userMap", clientConfig));
return p;
}
}
I am writing a JUnit test case for the method public Pipeline buildPipeline() but it's failing due to the resultset.
#ExtendWith(MockitoExtension.class)
public class UserJetJobTest extends JetTestSupport {
#InjectMocks
UserJetJob userJetJob;
#Mock
private JetInstance jet;
#Mock
private ClientConfig clientConfig;
#Test
public void buildPipelineUser() {
Pipeline p = Mockito.mock(Pipeline.class);
// Mockito.when(p.readFrom(Sources.jdbc(Mockito.anyString(), Mockito.anyString(), Mockito.eq(ResultSet.class))).then
userJetJob.buildPipeline();
}
}
Could you please help me with how to write JUnit test cases?
I can't mock my Feign Client using Mockito.
MyService.class
#Service
#AllArgsConstructor
public class MyService implements IMyService{
private static final Logger LOGGER = LoggerFactory.getLogger(MyService .class);
private final MyRepository repository;
private final MyFeignClient myFeignClient;
#Autowired
private MyDao myDao;
#Override
#Async
public void process(Map<UUID, Long> command) {
DocIds docIds = getDocIds(command.values().stream().findFirst().get());
archiveData(command.keySet().stream().findFirst().get(), documentIds.getIds());
}
private DocumentIds getDocIds(Long retentionId) {
return myFeignClient.getDocumentIds(retentionId);
}
private void archiveData(UUID execId, List<Long> docIds) {
List<MyDocument> myDocs= prepareMyDocs(docIds);
repository.saveAll(myDocs);
}
And my test class:
#RunWith(SpringRunner.class)
#SpringBootTest
#ActiveProfiles("test")
public class ArchiveServiceTest {
#Autowired
ArchiveService archiveService;
#MockBean
MyDao myDao;
#MockBean
DocRepository archiveRepository;
#MockBean
private MyFeignClient myFeignClient;
#Test
public void shouldReturnTheSameNumberOfDocumentsToArchive() {
//given
List<DocData> documentData = prepareDocumentData();
// doReturn(new DocIds()).when(myFeignClient).getDocumentIds(1000L);
DocumentIds documentIds = new DocumentIds();
documentIds.setIds(Arrays.asList(1L, 2L));
when(myFeignClient.getDocIds(any())).thenReturn(documentIds);
when(documentDataDao.getAllDocumentData(anyList())).thenReturn(documentData);
doNothing().when(archiveRepository.saveAll(any()));
//when
Map<UUID, Long> command = new HashMap<>();
command.put(UUID.randomUUID(), 1000L);
archiveService.process(command);
//then
...
MyFeignClient:
#FeignClient(name = "myFeignClient", url = "${feign.searcher.path}")
public interface MyFeignClient{
#RequestMapping(method = RequestMethod.GET, path = "/document/path/{id}")
DocIds getDocumentIds(#PathVariable("id") Long id);
}
When running a test,
return myFeignClient.getDocumentIds(retentionId);
returns NULL. Why?
I don't have more ideas. I don't want to use WireMock. The same happens with my documentDataDao that doesn't return any values (null) specified in thenReturn() clause.
Have You tried it this way:
Mockito.when(myFeignClient.getDocumentIds(Mockito.eq(1000L))).thenReturn(new DocIds());
In You example, mock is commented out ;)
// doReturn(new DocIds()).when(myFeignClient).getDocumentIds(1000L);
But I'm sure it is just a bug in Your example.
I'm trying to #MockBean a #Repository annotated class:
#Repository
public interface ApplicationDao extends MongoRepository<Application, String> {}
I'm injecting it into a #Service annotated class:
#Service
public class AuthorizationService {
private ApplicationDao appsDao;
private List<Application> allowedApplications;
#Autowired
public AuthorizationService(ApplicationDao appsDao) {
this.appsDao = appsDao; //<<MOCKED INJECTED BEAN>>
this.fillApplications();
}
private void fillApplications() {
this.appsDao.findAll() //<<MOCKED method>>
.forEach(entry -> {
this.allowedApplications.put(entry.getName(), entry);
});
}
public bool isAuthorized(Application application) {
return this.allowedApplications
.stream()
.anyMatch(app -> app.getId().equals(application.getId()));
}
}
My test mocking configuration looks like:
#RunWith(SpringRunner.class)
#SpringBootTest()
public class GroupReferencesTest {
private #Autowired AuthorizationService;
private #MockBean ApplicationDao applicationDao;
#Before
public void setUp() {
Application testApplication = new Application();
testApplication.setName("test-application");
List<Application> allowedApplications = new ArrayList<Application>();
allowedApplications.add(testApplication);
Mockito
.when(this.applicationDao.findAll())
.thenReturn(allowedApplications);
}
#Test
public void test() {
Application app = new Application();
app.getId("test-application");
assertTrue(this.authorizationService.isAuthorized(app)); //<<FAILS>>
}
}
Nevertheless, my mocked object is not injected. I mean, when my AuthorizationService calls its injected ApplicationDao is returns an empty list instead of my mocked list.
I've tried to use #MockBean(name="applicationDao") as well. The behavior is the same.
I've also tried to configure my mocked bean using this code:
#TestConfiguration
public class RestTemplateTestConfiguration {
#Bean("applicationDao")
#Primary
public static ApplicationDao mockApplicationDao() {
ApplicationDao mock = Mockito.mock(ApplicationDao.class);
Application testApplication = new Application();
testApplication.setName("test-application");
List<Application> allowedApplications = new ArrayList<Application>();
allowedApplications.add(testApplication);
Mockito
.when(mock.findAll())
.thenReturn(allowedApplications);
return mock;
}
}
However, it doesn't works right.
Application class is:
public class Application {
private String id;
//setters & getters
}
Any ideas?
First things first - the type of test. Answer: Unit test.
You are starting Spring context that manages a lifecycle of AuthorizationService and then you are trying to inject mock. What really happens is that Spring IoC container is injecting a real ApplicationDao (the one managed by Spring IoC container) into the AuthorizationService.
Solution:
Manage lifecyle of AuthorizationService by your test runner (like MockitoJUnitRunner and inject ApplicationDao mock into it):
#RunWith(MockitoJUnitRunner.class)
public class GroupReferencesTest {
private #InjectMocks AuthorizationService authorizationService;
private #Mock ApplicationDao applicationDao;
#Before
public void setUp() {
Application testApplication = new Application();
testApplication.setName("test-application");
List<Application> allowedApplications = new ArrayList<Application>();
allowedApplications.add(testApplication);
Mockito
.when(this.applicationDao.findAll())
.thenReturn(allowedApplications);
}
#Test
public void test() {
Application app = new Application();
app.getId("test-application");
assertTrue(this.authorizationService.isAuthorized(app));
}
}
Working example
#RunWith(SpringRunner.class)
#SpringBootTest(classes = {AuthorizationService.class})
public class GroupReferencesTest {
#Autowired
private AuthorizationService;
#MockBean
private ApplicationDao applicationDao;
#Test
public void test() {
//given
Mockito.when(applicationDao.findAll()).thenReturn(emptyList());
//when & then
assertTrue(authorizationService.isAuthorized(app));
}
}
I am using Spring boot and Mockito for testing. I have been able to write test cases for Service layer and they re working fine. But, the test cases for DAO layer do not. The jdbcTemplate object that is mocked and autowired gives null pointer when executing the test case. Below are the details:
My DAOTest class:
#RunWith(SpringRunner.class)
#SpringBootTest(classes = EcommerceApplication.class)
public classEcommerceDaoTest {
#InjectMocks
private IEcommerceDao ecommerceDao = new EcommerceDaoImpl();
#Mock
#Autowired
private JdbcTemplate as400JdbcTemplate;
#Before
public void setUp() throws Exception
{
MockitoAnnotations.initMocks(this);
}
#Test
public void checkOrderExistsTest() throws EcommerceException{
Mockito.when(as400JdbcTemplate.queryForObject(queryForOrder,new Object[]
{"1000"}, int.class)).thenReturn(1);
boolean exists =
ecommerceDao.checkOrderExists("1000");
assertTrue(exists);
}
}
EcommerceDAOImpl.java:
#Override
public boolean checkOrderExists(String orderNo)throws EcommerceException{
boolean doesExist = false;
int count = 0;
try{
count= as400JdbcTemplate.queryForObject(queryForOrder, new Object[]{orderNo}, int.class);
if(count >0){
doesExist = true;
}
}
catch(Exception e){
}
return doesExist;
}
AS400Config.java:
#Bean
#Autowired
public JdbcTemplate as400JdbcTemplate(#Qualifier("as400DataSource")DataSource dataSource) {
return new JdbcTemplate(dataSource);
}
ECommerceApplication.java
#SpringBootApplication(exclude = { DataSourceAutoConfiguration.class,
HibernateJpaAutoConfiguration.class,
DataSourceTransactionManagerAutoConfiguration.class })
#EnableTransactionManagement
#Import(As400Configuration.class)
public class EcommerceApplication {
public static void main(String[] args) {
SpringApplication.run(EcommerceApplication.class, args);
}
}
When I am running the test case, I am getting NullPointerException for as400JdbcTemplate. The functionality works fine as is. Its just the test cases for DAO layer that fail because of the inability of the jdbcTemplate to get mocked/autowired.
Please let me know where I am going wrong.
You don't need to use #Mock and #Autowired at the same time. Use only #Mock:
#Mock
private JdbcTemplate as400JdbcTemplate;
Use instead of #RunWith(SpringRunner.class) --> #RunWith(MockitoJUnitRunner.class)
Also to inject mock into DAO you can use ReflectionTestUtils from spring test.
public static void setField(Class targetClass, String name, Object value)
#Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
ReflectionTestUtils.setField(ecommerceDao ,"as400JdbcTemplate" ,
as400JdbcTemplate);
}
#Mock
private JdbcTemplate as400JdbcTemplate;
