I have rest service(PUT) which I intend to unit test it. I am using RestEasy for the Rest calls.
Here is my Resource :
#Path("/my_person")
public class MyResource {
private MyDAO myDao;
#Inject
public MyResource(MyDao myDao) {
this.myDao = myDao;
}
#PUT
#Timed
#Path("purchase_number/{purchaseNumber}/amount/{amount}/number_of_items")
#Produces(MediaType.APPLICATION_JSON)
public Response getItems(#PathParam("purchaseNumber") String purchaseNumber,
#PathParam("amount") String amount) {
return Response.ok(String.format("{\"items\": %d}", myDao.getItems(purchaseNumber, amount))).build();
}
}
The myDao.getItems returns an integer.
My Test class is as follows :
#RunWith(MockitoJUnitRunner.class)
public class MyResourceTest {
#Mock
private MyDao myDao;
#InjectMock
private MyResource myResource;
private TJWSEmbeddedJaxrsServer server;
private ResteasyClient resteasyClient;
#Before
public void startServer() throws IOException {
resteasyClient = new ResteasyClientBuilder().build();
server = new TJWSEmbeddedJaxrsServer();
server.setPort(PORT);
server.setBindAddress("localhost");
server.getDeployment().getResources().add(myResource);
server.start();
}
#After
public void stopServer() {
if (server != null) {
server.stop();
server = null;
}
}
#Test
public void testWhenValidInputGiven() {
String purchaseNumber = "A57697DF";
String amount = "340";
when(myDao.getItems(purchaseNumber, amount)).thenReturn(10);
Response response = resteasyClient.target("http://localhost:9980/my_person/purchase_number/{purchaseNumber}/amount/{amount}/number_of_items").request().buildPut(Entity.entity("{}", MediaType.APPLICATION_JSON))).invoke();
String text = response.getEntity().toString();
assertEquals(200, resp.getStatus());
assertEquals("{\"items\": 10}", text);
}
}
I get the following error at String text = response.getEntity().toString() since the entity object is null. So does it mean that it didn't create the request at all?

Have you tried to put / in front of you method path #Path("/purchase_number/{purchaseNumber}/amount/{amount}/number_of_items")
i think the framework misunderstood your path and expect my_personpurchase_number/.
Check your status code on response to see if actually get 200 back or a 404.
The solution to this problem was that I was using
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>jsr311-api</artifactId>
<version>1.1.1</version>
</dependency>
instead of
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>jaxrs-api</artifactId>
<version>3.0.10.Final</version>
</dependency>
both had the class javax.ws.rs.core.Response.

You shouldn't reassign your mocked ModelMapper in setup method. Remove this method
And I can't find in your code mock definition for mapper.getConfiguration()
when(mapper.getConfiguration()).thenReturn(...)
You should tell it to mockito.
I use spring framework 4 and have class that has his line :

what should I do?
It may be as easy as adding a MockHttpServletRequest in order to provide the needed RequestContextHolder and context path.
As a class variable, add
private MockHttpServletRequest mockRequest;
Then, when setting up your test(s), try:
#Before
mockRequest = new MockHttpServletRequest();
mockRequest.setContextPath("/your-app-context");
ServletRequestAttributes attrs = new ServletRequestAttributes(mockRequest);
RequestContextHolder.setRequestAttributes(attrs);
That should address that error.
I'm trying to mock a file upload (using Vertx) with Mockito but it throws a NullPointerError on getParam("type") used in when(event.request().getParam("type")).thenReturn("application/octet-stream");
My unit test is as follows:
private UploadResultatenHandler uploadResultatenHandler;
#Mock
RoutingContext event;
File folder;
Set<io.vertx.ext.web.FileUpload> upload;
HttpServerRequest httpServerRequest;
HttpServerResponse httpServerResponse;
#Before
public void setUp() {
uploadResultatenHandler = new UploadResultatenHandler();
MockitoAnnotations.initMocks(this);
when(event.request().getParam("type")).thenReturn("application/octet-stream");
when(event.fileUploads()).thenReturn(upload);
when(httpServerResponse.setStatusCode(200)).thenReturn(httpServerResponse);
when(event.response()).thenReturn(httpServerResponse);
}
#Test
public void testCleanHandler() {
uploadResultatenHandler.handle(event);
verify(event).response();
}
"uploadResultatenHandler.handle(event);" :
#Override
public void handle(RoutingContext event) {
String newFileName = event.request().getParam("type");
Set<FileUpload> uploads = event.fileUploads();
System.out.println(uploads);
for (FileUpload fileUpload : uploads) {
String oldFileName = fileUpload.uploadedFileName();
char[] inhoud = FileReader.readFileUTF8ToString(oldFileName).toCharArray();
String fileExtention = setFileExtension(fileUpload.contentType());
FileCreater.createFile(newFileName, fileExtention, "file-uploads/", inhoud);
FileDeleter.deleteFile(oldFileName);
}
event.response().setStatusCode(200).end("Check");
}
private String setFileExtension(String type) {
switch (type) {
case "text/xml":
return ".xml";
case "application/octet-stream":
return ".json";
default:
return ".txt";
}
}
I think it might have something to do with the mocked RoutingContext not having this parameter, but I don't know how to fix / bypass this error?
I changed the line to when(event.request()).thenReturn(request); when(request.getParam("type")).thenReturn("application/octet-stream"); and the mocks to: Mock(answer = Answers.RETURNS_DEEP_STUBS) RoutingContext event; #Mock File folder; Set upload; HttpServerRequest request; HttpServerResponse response; but I'm still getting a NullPointer

Since you haven't recorded any behavior for event.request(), it will return null. Calling getParam on it will, of course, fail with a NullPointerException. There are a few ways around it, but the most elegant, IMHO, would be to use deep stubbing:
#Mock(answer = Answers.RETURNS_DEEP_STUBS)
RoutingContext event;
mocking does not work recursively.
you must split this line
when(event.request().getParam("type")).thenReturn("application/octet-stream");
to this
Request request = mock(Request.class);
when(event.request()).thenReturn(request);
when(request.getParam("type")).thenReturn("application/octet-stream");

Please, tell me, what I must to do, that solved this problem?
This is my code
public class DaoFactoryImpl implements DaoFactory {
private ConnectionPool connectionPool;
public DaoFactoryImpl() {
connectionPool = new ConnectionPool();
}
private Connection getConnection(){
try {
return connectionPool.getConnection();
} catch (SQLException e) {
e.printStackTrace();
}
return null;
}
public UserDaoImpl getUserDao() {
return new UserDaoImpl(getConnection());
}
public SecurityUserDaoImpl getSecurityDao() {
return null;
}
}
public abstract class BaseDaoTest {
protected DaoFactory daoFactory;
#Before
public void init(){
daoFactory = new DaoFactoryImpl();
}
}
public class UserDaoTest extends BaseDaoTest{
private UserDaoImpl userDao;
private User user;
#Before
public void init(){
userDao = daoFactory.getUserDao();
SecurityUserDaoImpl securityDao = daoFactory.getSecurityDao();
SecurityUserCredentials security = new SecurityUserCredentials();
security.setAuthToken("TestToken");
security.setRole(UserRole.REGISTER_USER);
security.setActivate(true);
SecurityUserCredentials resultSecurity = securityDao.create(security);
user = new User();
user.setSecurity(resultSecurity);
user.setLogin("TestLogin");
user.setPassword("TestPass");
}
#Test
public void testAddUserInDataBase(){
User testUser = userDao.create(user);
assertNotNull(testUser);
assertEquals(testUser.getLogin(), "TestLogin");
assertEquals(testUser.getPassword(), "TestPass");
}
}
We have created test for the functionality via springframework.test.context.junit4.
Below is one of the test case :
Test Class
#Test
public void testAuthorizedPut() throws Exception {
ThreadContext.bind(subject);
when(subject.isPermitted(getPlural() + ":put")).thenReturn(true);
when(subject.isPermitted(getPlural() + ":get")).thenReturn(true);
assertThat(adminTemplate().exchange(getTestHost() + "/api/1/" + getPlural() + "/45454-67567d-f5224666a9", HttpMethod.PUT, new HttpEntity<Object>(getInstance(),getStandardHeaders()),entityClass).getBody(), equalTo(getInstance()));
}
When code move to resource class that are used to mock. Like for above test code will move to PUT request of resources :
MyResource Class
#ApiOperation(value = "Update MyResource definition", notes = "Enter the id of the MyResource definition, returns updated MyResource definition", response = MyResource.class)
#Path("/{id}")
#PUT
#Timed
#Override
public MyResource update(#PathParam("id") String id, MyResource newInstance) {
return super.update(id, newInstance);
}
When we run the test written above testAuthorizedPut then it throw below error :
java.lang.AssertionError:
Expected: <MyResource(id=null, metadataTemplate=null, name=null, shortLabel=null, description=null, embedInObject=false, optional=false, type=null, possibleValues=null)>

BUT when I write resource class PUT as, means return newInstance separate solve the above error:
public MyResource update(#PathParam("id") String id, MyResource newInstance) {
super.update(id, newInstance);
return newInstance;
}
So what is the difference of returning newInstance with super calls OR separate call. How can this error resolved without above changes?
code from inherited Update() method would be apreciated.
And, well, you return recieved object from method in one case and in the second you return object from method parameter in that same method.
And the answer to your question lies in super.update() blackBox.
For all I know it could be
MyResource update(){
return null;
}
and this would explain the output. You should inspect why super.update returned null.
