Configure spring cloud contract and Zuul proxy in the same project - spring-cloud

I have a problem with integrating spring-cloud-contract with my service on the consumer side. In my service I use already feign (to call other services) and zuul (for routing) from spring-cloud. The problem happens when I try to run a test annotated with #AutoConfigureStubRunner. This my simple class:
#RunWith(SpringRunner.class)
#SpringBootTest
#AutoConfigureStubRunner(ids = {"group:artifact:+:stubs:8080"}, workOffline = true)
public class WithContractTests {
#Test
public void test() {}
}
In the output I can see that stubs were started properly:
o.s.c.c.stubrunner.StubRunnerExecutor : All stubs are now running RunningStubs [namesAndPorts={group:artifact:1.0.0-SNAPSHOT:stubs=8080}]
And then I have this error while creating spring context:

What is interesting is that the same error occurs in the spring-cloud-contract example:
https://github.com/spring-cloud/spring-cloud-contract/tree/master/samples/standalone/dsl/http-client after adding Zuul to the project. By adding Zuul I mean adding spring-cloud-starter-zuul as dependency and #EnableZuulProxy annotation. After that we can see a following error while executing the test:

Do I need some additional configuration when using Zuul together with Stub runner?

Oh boy this is my mistake. Can you file an issue in contract? Until now you would have to do is to override the existing class woth sth that doesn't add servers to a list returned from a delegate but creates a new list to which the servers are added. I haven't tested that against Zuul :/
It's been fixed (hopefully) here - https://github.com/spring-cloud/spring-cloud-contract/issues/82

Missing header error when running springboot rest test

Getting a strange error when executing an integration test for a microservice generated with JHipster(springboot)
This is the REST endpoint:
#RestController
#RequestMapping("/api")
public class MealResource {
private MealService mealService;
public MealResource(MealService mealService) {
this.mealService = mealService;
}
#PostMapping("/meals")
#Timed
public ResponseEntity<Meal> createMeal(#Valid #RequestBody Meal meal) throws URISyntaxException {
log.info("REST request to save Meal : {}", meal);
String newMealId = mealService.save(meal);
return ResponseEntity.created(new URI("/api/meals/" + newMealId))
.headers(HeaderUtil.createEntityCreationAlert("meal", newMealId))
.body(meal);
}
This is the failing test:
#Test
public void createMealTest() throws Exception {
restProfileMockMvc
.perform(post("/api/meals")
.header("Content-Type", "application/json")
.contentType(TestUtil.APPLICATION_JSON_UTF8)
.content(TestUtil.convertObjectToJsonBytes(createMeal())))
.andExpect(status().isCreated())
.andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8_VALUE));
}
This is the error message:

I've done some debugging but I can't find out what's the specific header that is missing, ideas?
Thank you!
To whom it may concern - you are adding null header in the controller.
It seems that your
mealService.save(meal);
from controller returns null and that's why you have the assertion failing

Spring Rest Docs error - "No content to map due to end-of-input"

I have a test case on the Get method with Spring Rest Docs. It runs fine. With the same fashion of code on the Post method as the following:
Foo foo = new Foo(...);
this.mockMvc.perform(post("/foos")
.contentType(APPLICATION_JSON_UTF8)
.content(objectMapper.writeValueAsString(foo)))
.andExpect(status().isCreated())
.andExpect(header().string("Location", notNullValue()))
.andDo(document("foo-post", preprocessResponse(prettyPrint()),
links(
halLinks(),
linkWithRel("self").description("..."),
linkWithRel("foo").description("...")),
responseFields(
fieldWithPath("attr1").description("..."),
fieldWithPath("attr2").description("..."),
...
fieldWithPath("_links").description("<<resource-book-links,links>> to other resources")
)
));
I get an error, however.

If I comment out anything after "andDo(..)", it is fine. That means the problem is in the document section.
What is missing?
Your tests using MockMvc are not setting an Accept header in the POST request. That means that, by default, Spring Data REST does not include a body in its 201 Created response. You either need to configure Spring Data REST to always return a body for create requests or you need to change your tests to send an Accept header.

org.apache.cxf.interceptor.Fault: Marshalling Error: ELEMENT_NAME_MISMATCH

I am new to apache cxf. I was using a cxf Interceptor to intercept my soap response and send a custom fault mesaage. Everything works fine when i try from Soap UI. But when i run tests , i get the correct response followed by this error "org.apache.cxf.interceptor.Fault: Marshalling Error: ELEMENT_NAME_MISMATCH" due to which tests failed.
Error (The Weird thing is i get the soap response back before this error gets thrown)

Finally figured out the error. Its because my test client wasn't able unmarshall the response properly due to mismatch in the QName. I was following a code first approach, so had to manually create a "package-info.java" like this and mention my Qname.

Dropwizard test - javax.validation.ConstraintViolationException: The request entity was empty

I am writing integration tests for REST services with Dropwizard 0.7. I am following Dropwizard documentation http://dropwizard.readthedocs.org/en/latest/manual/testing.html
I am trying test simple get request using io.dropwizard.testing library.
<dependency>
<groupId>io.dropwizard</groupId>
<artifactId>dropwizard-testing</artifactId>
<version>0.7.1</version>
</dependency>
My code is:
#ClassRule
public static final ResourceTestRule resources = ResourceTestRule.builder()
.addResource(new EvaluationResource())
.build();
#Test
public void testGetPrompt() {
List<Class<?>> mappedClasses = config();
HibernateUtil.init(ADeployer.DEPLOYMENT_DIR, "localhost", 3306, "stat", mappedClasses);
UserIdentity userIdentity = UserIdentityDAO.validate(new Long(1), "asdfasdf", "Slavina");
String token = UserIdentityDAO.generateToken(userIdentity);
User user = userManager.getUser(token);
resources.builder().setMapper(MAPPER);
resources.client().resource("https://localhost:8080/execute/prompt?sessionKey=" + token).type(MediaType.APPLICATION_JSON).get(User.class);
}
My method is:
#GET
#Path("/prompt")
public String getPromptMessage(#SessionAuth User user) {
try {
Autosave status = user.getWorker().getStatus(user.getSessionKey());
return status.getPendingPromptMessage();
}
catch (Exception e) {
throw new RestException(e);
}
}
What I get is successfully connected to db, I got the right token and Exception is:

For sure I am doing something wrong passing parameters, but I couldn't find out what, can you help me?
I had a lot of trouble with a problem very similar to this, and have just found the fix, which I'm hoping will help here also.
In my case the reason for the "ConstraintViolationException: The request entity was empty at " exception is because when the Resource mock is being constructed it runs through all of the annotations and compares them to a map of annotations it expects. None of these are #SessionAuth, or #Auth(which I was using), so by default it assumes that annotation must mean that its related parameter is the entity. In the case of a get request there isn't an entity, so it bombs out.
The solution appears to be to call .addProvider in your ResourceTestRule builder, so it can look for an understand the annotation. For example I had to do:
#Rule
public final ResourceTestRule resources = ResourceTestRule.builder()
.addResource(new GroupSuggestionsResourceV1(RANKING_STORE, CLIENT))
.addProvider(new OAuthProvider<>(AUTHENTICATOR, "test-realm"))
.build();
which told the resource builder to expect an auth annotation, and handle it appropriately. Initially I was just doing .addProvider(AUTHENTICATOR) but that didn't work, so if you have trouble you might want to try both.
I hope this helps other people with this problem!
