在另一个服务Junit中模拟服务的服务
在另一个服务Junit中模拟服务的服务
提问于 2017-09-19 14:02:06
我有以下服务：
@Service
public class AccountServiceImpl implements AccountService {
@Autowired
protected ContractService contractService;
private void saveInCache(MultipartFile multipartFile) {
this.contractService.saveInCache(multipartFile);
}
}和另一项服务
@Service
public class ClientServiceImpl implements ClientService {
@Autowired
protected ContractService contractService;
private void getInfoOfFile(String multipartFileId) {
DocumentInfo document = this.contractService.getInfo(multipartFileId);
///
}
}我有我的Junit
public class ClientControllerTest extends ApiWebTest {
@Mock
protected ContractService contractService;
@Autowired
@InjectMocks
protected ClientService clientService = new ClientServiceImpl();
@Before
private void setup() {
MockitoAnnotations.initMocks(this);
}
@Test
private void testGetInfo() {
// Code
DocumentInfo multipartFile = new DocumentInfo();
multipartFile.setMultipartFileId(1234);
when(this.contractService.getInfo(multipartFile.getMultipartFileId())).thenReturn(multipartFile);
// Test the Client service 'getInfoOfFile' method.
}
}当我在调试模式下运行这个测试时，我看到this.contractService.getInfo(multipartFileId);返回给我'null‘。
在嘲笑中，我哪里错了？
我刚刚在我的JUnit中模拟了ContractService。我甚至还需要模拟AccountServiceImpl吗？
编辑:添加saveInCache和getInfo方法
private DocumentInfo getInfo(String documentId) {
if (StringUtils.isEmpty(documentId)) {
return null;
}
WriteLock lock = this.readWriteLock.writeLock();
try {
lock.lock();
DocumentInfo cachedDocument = this.documentCache.get(documentId);
return cachedDocument;
} finally {
if (lock != null) {
lock.unlock();
}
}
}
private DocumentInfo saveInCache(StreamingStorage document) {
if (document == null) {
throw new InvalidParameterException("Creative document is required to put into cache.");
}
WriteLock lock = this.readWriteLock.writeLock();
try {
lock.lock();
DocumentInfo newCachedDocument = this.documentCache.put(document.getDocumentId(), document);
return newCachedDocument;
} finally {
if (lock != null) {
lock.unlock();
}
}

根本原因:您没有将ContractService注入ClientService。
我认为使用ReflectionTestUtils.可以更容易地解决这个问题。这意味着您将向AccountServiceImpl注入模拟的ContractService。
public class ClientControllerTest extends ApiWebTest {
protected ClientService clientService = new ClientServiceImpl();
private ContractService contractService;
@Test
private void testGetInfo()
{
// Code
DocumentInfo multipartFile = new DocumentInfo();
multipartFile.setMultipartFileId(1234);
contractService= EasyMock.createNiceMock(ContractService.class);
ReflectionTestUtils.setField(clientService, "contractService", contractService);
EasyMock.expect(contractService.getInfo(multipartFile.getMultipartFileId())).andReturn(multipartFile).anyTimes();
EasyMock.replay(contractService);
}
}您可以将相同的方法应用于JUnit
