Response status and type verification error

[aaguila]

Hi,

I have an example project (https://github.com/QAJungle/vertx-testing-example) where I have a Vertx application. I'm doing pact testing.

One of the problems is that when I launch a GetABookByISBNPactTest GetABookByNamePactTest or GetAllBooksPactTest (https://github.com/QAJungle/vertx-testing-example/tree/master/vertx-testing-example-server/src/test/java/com/qajungle/vertx) I obtain the next error, but is random, not alwails fails.

java.lang.AssertionError: 0 - Expected a header 'Content-Type' but was missing 1 - Expected a response type of 'application/json' but the actual type was 'text/plain'

The second error is status assertion error with AddABookPactTest. When I launch tests I obtain the next error:

java.lang.AssertionError: 0 - expected status of 201 but was 200

If you see the pact (https://github.com/QAJungle/vertx-testing-example/blob/master/vertx-testing-example-server/src/test/resources/pacts/add_book_test_consumer-add_book_test_provider.json) and controller code (https://github.com/QAJungle/vertx-testing-example/blob/master/vertx-testing-example-server/src/main/java/com/qajungle/vertx/infrastructure/delivery/vertx/controller/BookController.java#L47) I send 201 status code. In postman I validated it correctly.

You can see the provider and the client in the same repo.

I use: pact-jvm-provider-junit5_2.12 3.6.2 version.

Thanks.

I don't know much about vert.x, but I can see a difference when running the app versus when the pact test runs.

With the app running:

$ curl -v http://localhost:8080/books/978-0-321-53446-0
*   Trying 127.0.0.1...
* TCP_NODELAY set
* Expire in 200 ms for 4 (transfer 0x55c7ea9295c0)
* Connected to localhost (127.0.0.1) port 8080 (#0)
> GET /books/978-0-321-53446-0 HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.64.0
> Accept: */*

< 
{
  "name" : "Agile Testing",
  "isbn" : "978-0-321-53446-0"
* Connection #0 to host localhost left intact
}

and when the pact test is run with debug logging enabled:

Failures:

      Expected a header 'Content-Type' but was missing

1) Verifying a pact between get_book_by_isbn_test_consumer and get_book_by_isbn_test_provider - GET REQUEST returns a response which has a matching body
      comparison -> Expected a response type of 'application/json' but the actual type was 'text/plain'

particularly, the line headers={content-length=[0]}, contentType=application/json; charset=UTF-8, data=} shows that the content type header is not being set correctly. It should be content-Type not contentType.

Changing VertxPactTest.java:36 to .requestHandler(req -> req.response().putHeader("content-type", "application/json; charset=utf-8").end()) fixes that problem, but the test still fails because no response is being generated.

Any solutions to that problem? I am also getting the same issue when doing a GET request with a query param. Any help would be valuable @bethesque Thanks

[bethesque]

Sorry, I'm not the pact-JVM maintainer, and I don't do much Java, so I can't give you any insight into this issue.

[kumarkrish85]

Any solution for this issue!? facing the same error.

0 - Expected a response type of 'application/json' but the actual type was 'text/plain' 1 - Expected a header 'Content-Type' but was missing

[kumarkrish85]

@uglyog can you please help?

[sbartsa]

In my case I think it was the messageConverters in the mockMVC target which were not setup correct. (JsonHttpMessageConverter and ProtobufHttpMessageConverter) Also I suggest taking a look at all the pact-jvm dependencies to all align at the same version.

[uglyog]

@kumarkrish85 are you also using a Vertx application?

I am also facing the same issue 0 - Expected a header 'Content-Type' but was missing 1 - Expected a response type of 'application/json' but the actual type was 'text/plain'

@praneeth459 are you also using a Vertx application?

0 - Expected a header 'Content-Type' but was missing 1 - expected status of 200 but was 404 2 - Expected a response type of 'application/json' but the actual type was 'text/plain'
