I would like to test the endpoint if the response and HTTP code are correct. The controller method looks like this:
#CrossOrigin
#RequestMapping(method = RequestMethod.GET, value = "/{ruleId}")
public Rule loadOneRule(#PathVariable String ruleId) {
return rulesService.loadOneRule(ruleId);
}
The test method is
#Test
public void loadOneRule() throws IOException, URISyntaxException {
NodeDTO nodeDto = new NodeDTO();
HashMap<String, NodeDTO> nodes = new HashMap<>();
nodes.put("foo", nodeDto);
Rule rule = new Rule("my rule", nodes);
RuleService ruleService = new RuleService();
rule = ruleService.saveRule(rule);
String id = rule.getId().toString();
String target = "http://localhost:8090" + "/v2/rules/" + id;
URI uri = new URI(target);
HttpGet httpGet = new HttpGet(uri.toASCIIString());
HttpResponse response = httpClient.execute(httpGet);
int HTTPcode = response.getStatusLine().getStatusCode();
HttpEntity entity = response.getEntity();
String json = EntityUtils.toString(entity);
ObjectMapper objectMapper = new ObjectMapper();
Rule targetRule = objectMapper.readValue(json, Rule.class);
boolean correctStatus = HTTPcode >= 200 && HTTPcode <= 300 ? true : false;
boolean correctResponse = targetRule != null ? true : false;
assertTrue(correctStatus);
assertTrue(correctResponse);
}
I get nullpointer exception on my ruleService. It is the same even if I try to #Autowire it and not instantiate it. I guess the whole approach about getting one rule object from the mongo database is wrong, but putting an object locally in my database and getting this object by his id would be even worse, since these tests will not run on my computer.
This is the exception if I try to autowire my service

You don't need make request using HttpClient, rather you can use #WebMVCTest to test your controller. One more thing, you don't need to specify the dependencies by creating objects rather mock them using #MockBean. In code below you specify the exact controller name within #WebMvcTest annotation.
#RunWith(SpringRunner.class)
#WebMvcTest(value = YourController.class, secure = false)
public class YourControllerTest {
#Autowired
private MockMvc mockMvc;
#MockBean
private StudentService rulesService;
Rule mockRule = new Rule();
#Test
public void testLoadOneRule() throws Exception {
Mockito.when(
rulesService.loadOneRule(Mockito.anyString(),
Mockito.anyString())).thenReturn(mockCourse);
RequestBuilder requestBuilder = MockMvcRequestBuilders.get(
"/{ruleId}","rule1")
MvcResult result = mockMvc.perform(requestBuilder).andReturn();
System.out.println(result.getResponse());
String expected = "{id:rule1,name:'RuleName'}";
JSONAssert.assertEquals(expected, result.getResponse()
.getContentAsString(), false);
}
}

I am trying to write a test case for following controller code using JUnit.
But I am getting 500 code with null pointer Exception. (When I test this on Postman, it works without any exception.) I think HttpServeleRequest Request of validEmp might cause this null pointer exception to testGetMethod. Can any one please tell what I am doing wrong here and how to fix this? Thank you for your help:D
LoginService
public ReturnParam validEmp(HttpServletRequest request, String locale, String empKey, String accessToken) throws Exception {
ReturnParam rp = new ReturnParam();
rp.setFail("not available");
return rp;
}
LoginController
#RequestMapping(value = "/valid", method = RequestMethod.GET, produces = "application/json; charset=UTF-8")
public #ResponseBody ReturnParam validEmp(HttpServletRequest request,
#RequestParam(value = "locale", required = true) String locale,
#RequestParam(value = "empKey", required = true) String empKey,
#RequestParam(value = "accessToken", required = true) String accessToken) throws Exception {
return service.validEmp(request, locale, empKey, accessToken);
}
LoginControllerTest
public MockMvc mockMvc;
private MediaType contentType = new MediaType(MediaType.APPLICATION_JSON.getType(),
MediaType.APPLICATION_JSON.getSubtype(), Charset.forName("utf8"));

You need to mock your LoginService in LoginController. Try to add such code to LoginControllerTest.
#Mock
private LoginService loginService;
#InjectMocks
private LoginController loginController;
#Before
public void init(){
MockitoAnnotations.initMocks(this);
mockMvc = MockMvcBuilders
.standaloneSetup(loginController)
.build();
}
I think problem ist not a request , but injection. According your stacktrace I would say, that service is null (injection in controller isn't working)
I have a method that is using findById() method of Spring Data JPA. However, this method is returning ClassCastException on line number 1 of the getSupportedKey() method where I am calling findById():
MySupportedKey cannot be cast to java.util.Optional
private MySupportedKey getSupportedKey(String tenant, String key) {
Optional<MySupportedKey> mySupportedKeyOptional = mySupportedKeyRepository.findById(new MySupportedKeyId(tenant, key));
MySupportedKey mySupportedKey= null;
if(mySupportedKeyOptional !=null) {
mySupportedKey= mySupportedKeyOptional.orElse(null);
}
return mySupportedKey;
}
I have been beating my head for a long time but I am not getting anything. Please help me in getting this resolved. I am using spring-data-jpa: 2.0.8.RELEASE.
Adding the Repository Source Code:
public interface MySupportedKeyRepository extends JpaRepository<MySupportedKey, MySupportedKeyId> {

You set up a Mockito mock for the repository and probably told it to return a MySupportedKey instance when findById gets called.
But since findById is supposed to return an Optional you now get the exception.
You can see that this is coming from Mockito in the very first two lines of the stack trace.
java.lang.ClassCastException: com.test.service.user.entity.MySupportedKey cannot be cast to java.util.Optional
at com.test.service.user.repository.MySupportedKeyRepository$MockitoMock$1304362870.findById(Unknown Source)
Modify the Optional handling in your below method to get the correct representation like below:
private MySupportedKey getSupportedKey(String tenant, String key) {
Optional<MySupportedKey> mySupportedKeyOptional = mySupportedKeyRepository.findById(new MySupportedKeyId(tenant, key));
MySupportedKey mySupportedKey= null;
if(mySupportedKeyOptional.isPresent()) {
mySupportedKey= mySupportedKeyOptional.get();
}
return mySupportedKey;
}
Cannot add comment, just wanted to elaborate on Jens answer since it took me a while to figure out how to fix this (being a newbie).
To fix the issue I changed my code from:
when(mongoRepository.findById(Mockito.anyString())).thenAnswer(new Answer<MongoObj>() {
#Override
public MongoObj answer(InvocationOnMock invocation) throws Throwable {
MongoObj repush = new MongoObj();
//Some other code
return repush;
}
});
To
when(mongoRepository.findById(Mockito.anyString())).thenAnswer(new Answer<Optional<MongoObj>>() {
#Override
public Optional<MongoObj> answer(InvocationOnMock invocation) throws Throwable {
MongoObj repush = new MongoObj();
//Some other code
return Optional.of(repush);
}
});
Hope this helps!
I got a main project, that I have to test now...
I made a second project for that, in that project, I pasted the interfaces and entities from the main project, and now I made a simple jUnit test case...
Looks like this:
public class TestLogin {
String path = "http://localhost:8080/rest/dss"; //thats the right path...
ResteasyClient client = new ResteasyClientBuilder().build();
ResteasyWebTarget rtarget = client.target(path);
DssRest rest = rtarget.proxy(DssRest.class);
#Test
public void test() {
assert(rest.login(null, "Test", "Test") != -1);
}
}
DssRest, interface
#POST
#Produces(MediaType.APPLICATION_JSON)
#Path("/login/{userName}/{password}")
int login(#Context HttpServletRequest req, #PathParam("userName") String userName,
#PathParam("password") String password);
from there I go to the DssBean, where the function is that I wanna test
#Override
public int login(HttpServletRequest req, String userName, String password) {
ResteasyClient client = new ResteasyClientBuilder().build();
ResteasyWebTarget rtarget = client.target(".../rest/mw"); //real path
MWRest rest = rtarget.proxy(MWRest.class);
int userId = rest.login(userName, password);
...
return userId; //it always is > -1
}
From there, I call the MWRest, an interface of my second project...and that project has the same function, which returns an INT, 12 for exemple...
now....to test that, made a junit test suite
#RunWith(Suite.class)
#SuiteClasses({TestLogin.class})
public class AllTests {
}
Before I run it, I made sure, the 2 projects I need to test are running...
Then I run the suite, as jUnit test, and on the JUnit console, there is this error, which I simply cannot figure out.
I hope you can help....thx

I wrote a service which can upload a file to the server, and now I'm writing it's integration test with REST Assured. The functional code is as following:
/* Upload a new document */
#RequestMapping(method = RequestMethod.POST)
public ResponseEntity uploadDocument(#RequestPart("file") final MultipartFile file, final HttpServletRequest request) throws IOException {
final String id = documentService.saveDocument(file);
final String url = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + "/documents/" + id;
return ControllerUtil.resourceCreatedMessage(id, url);
}
To use this service, I always upload a file in Postman, and I didn't add "Content-Type = multipart/form-data" in the Headers, it works perfectly:
If I add the header info "Content-Type = multipart/form-data", I will get the message that "400 - Request is not a multipart request, see details for more information". This part also confused me because in the upper image you can see I'm sending a file in "form-data", how could it not be a multipart request?
Anyway, I am writing the integration test:
#Test
public void testDocuments() throws URISyntaxException {
// Test post a document.
given().multiPart("file", new File(LOCATE_TO_THE_TEST_HTML_FILE))
.expect().statusCode(201).when()
.post(HOST + "/documents");
}
but I got the 415 error:
java.lang.AssertionError: 1 expectation failed.
Expected status code <201> doesn't match actual status code <415>.

I tried to add ".contentType("multipart/form-data")" but the same error occured. Can anyone help me?
Finally found the reason that I should specify the data type of the file in the following way:
.multiPart("file", new File(TestUtil.getFileURI("/examples/help.html")), "text/html")
This is a way where I can send the video in post API using multipart.
File file = new File("File Path");
String endpoint = "/api/v3/abc";
RestAssured.baseURI = "http://dummy.com/";
Response res = given()
.formParam("token", "eacca99696ac5")
.multiPart("media_url", file,"application/json")
.when().post(endpoint);
So In my point I needed to upload 2 files and also Json file
This how i success to solve it:
when file1 and file2 are the Path to the files
public static Response Post(JSONObject body, String URL, String file1, String file2) {
try {
return RestAssured.given().baseUri(URL).urlEncodingEnabled(false)
.accept("application/json, text/plain, */*")
.multiPart("data",body,"application/json")
.multiPart("file[0]", new File(file1),"multipart/form-data")
.multiPart("file[1]", new File(file2),"multipart/form-data")
.relaxedHTTPSValidation().when().post();
} catch (Exception e) {
System.out.println(e);
return null;
}
}
could you please help me.
I try to implement an JUnit-Test for a Restcontroller with parameter PersistentEntityResourceAssembler.
Here is my RestController:
import java.util.Map;
import org.apache.camel.ProducerTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.rest.webmvc.PersistentEntityResourceAssembler;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestHeader;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class GreetingController2 {
#Autowired
ProducerTemplate pt;
#RequestMapping(value = "/greeting2", method = RequestMethod.POST)
public ResponseEntity<Greeting> updateGreeting( PersistentEntityResourceAssembler assembler,
#RequestHeader HttpHeaders header, #RequestBody Greeting greeting) {
Map<String, Object> headers = (Map) header.toSingleValueMap();
greeting=(Greeting) pt.requestBodyAndHeaders("direct:start", greeting, headers);
return new ResponseEntity<Greeting>(greeting, HttpStatus.OK);
}
}
And my JunitTest:
public class GreetingControllerMocksTest2 extends AbstractControllerTest2 {
#Mock
private ProducerTemplate producerTemplate;
#InjectMocks
private GreetingController2 greetingController2;
#Before
public void setUp() {
// Initialize Mockito annotated components
MockitoAnnotations.initMocks(this);
// Prepare the Spring MVC Mock components for standalone testing
setUp(greetingController2);
}
#Test
public void testRestEndpoint() throws Exception {
// Create some test data
Greeting entity = new Greeting(5,"Rudi");
// Stub the GreetingService.update method return value
when(producerTemplate.requestBodyAndHeaders(anyString(),anyObject(),
anyObject())).thenReturn(entity);
// Perform the behavior being tested
String uri = "/greeting2";
String inputJson = super.mapToJson(entity);
MvcResult result = mvc
.perform(MockMvcRequestBuilders.post(uri)
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON).content(inputJson))
.andReturn();
// Extract the response status and body
String content = result.getResponse().getContentAsString();
int status = result.getResponse().getStatus();
// Verify the GreetingService.update method was invoked once
verify(producerTemplate,
times(1)).requestBodyAndHeaders(anyString(),anyObject(),anyObject());
// Perform standard JUnit assertions on the test results
Assert.assertEquals("failure - expected HTTP status 200", 200, status);
Assert.assertTrue(
"failure - expected HTTP response body to have a value",
content.trim().length() > 0);
Greeting updatedEntity = super.mapFromJson(content, Greeting.class);
Assert.assertNotNull("failure - expected entity not null",
updatedEntity);
}
}
When starting the junit-test i get the following Exception:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.rest.webmvc.PersistentEntityResourceAssembler]: No default constructor found; nested exception is java.lang.NoSuchMethodException: org.springframework.data.rest.webmvc.PersistentEntityResourceAssembler.<init>()

If i remove the paramter PersistentEntityResourceAssembler, then everthing works fine. But der RestController is generated by a tool, so it is not possible for me to remove this.
From your controller method I don't see if you are using PersistentEntityResourceAssembler. Please check your use case. To fix this, in your controller, you can use #RepositoryRestController instead of #RestController. Please check http://docs.spring.io/spring-data/rest/docs/current/reference/html/#customizing-sdr.overriding-sdr-response-handlers. I found the similar issue has been reported for some different use case. This issue is still in open state. https://jira.spring.io/browse/DATAREST-657
It seems that you have missed something.
I faced this error and fixed it, the problem was that I forgot to add an annotation #RequestBody to the parameter of the method.
Next code works fine:
//interface:
#ResponseStatus(value = HttpStatus.ACCEPTED)
#RequestMapping(method = RequestMethod.POST, produces = { MediaType.APPLICATION_JSON_VALUE }, consumes = { MediaType.APPLICATION_JSON_VALUE })
public Message greeting(#RequestBody GreetingRequestMessage requestMessage);
//implementation:
public Message greeting(#RequestBody GreetingRequestMessage requestMessage) {
}
//setup #Before:
mvc = MockMvcBuilders.standaloneSetup(testObj).build();
GreetingRequestMessage requestMessage = new GreetingRequestMessage();
payloadString = mapper.writeValueAsString(requestMessage);
//test:
payloadString = mapper.writeValueAsString(request);
mvc.perform(
MockMvcRequestBuilders.post("/greeting")
.content(payloadString)
.contentType(MediaType.APPLICATION_JSON).accept(MediaType.APPLICATION_JSON))
.andExpect(status().is(202));
