quarkus-quickstarts/rest-jsonb Posting a Fruit object without programmatically marshall a Fruit to JSon

In the rest-json quickstart, the FruitResourceTest.testAdd test case posts a JSon representation of a fruit

given()
    .body("{\"name\": \"Pear\", \"description\": \"Winter fruit\"}")

It would be good to have a test that passes the Fruit object itself

Fruit pear = new Fruit("Pear", "Winter fruit");
given()
    .body(pear)

If write the previous code, the test fails because of an XML exception (which is a bit annoying for a JSon quickstart

javax.xml.bind.MarshalException
 - with linked exception:
[com.sun.istack.internal.SAXException2: unable to marshal type "org.acme.rest.json.Fruit" as an element because it is missing an @XmlRootElement annotation]

If we add the @XmlRootElement annotation to Fruit and change all the MediaType to XML instead of JSon it works (but hey, again, for a JSON Quickstart this is not great)

Using JSON-B I can cheat and marshall the Fruit object programmatically to a JSon String

Jsonb jsonb = JsonbBuilder.create();
Fruit pear = new Fruit("Pear", "Winter fruit");
String pearJson = jsonb.toJson(pear);
given()
        .body(pearJson)
        .header("Content-Type", MediaType.APPLICATION_JSON)

Is there an easy way to just pass the Fruit object and leave Quarkus do the marhalling Object -> JSon without programmatically using JSON-B and being able to just write :

Fruit pear = new Fruit("Pear", "Winter fruit");
given()
    .body(pear)

Looks like RestAssured.objectMapper(mapper); has been removed in 4.2.0 (and it looks like Quarkus 1.3.0, depends on this version) https://github.com/rest-assured/rest-assured/pull/1257#issuecomment-575677954 You can still use

RestAssured.config = RestAssured.config().objectMapperConfig(
  ObjectMapperConfig.objectMapperConfig().defaultObjectMapper(mapper)
);

I tried to test

RestAssured.config = RestAssured.config.objectMapperConfig(
    ObjectMapperConfig.objectMapperConfig().defaultObjectMapperType(ObjectMapperType.JSON)
);

Without success … where the “old” way to define the default objecy mapper works (the one above)

groovy.lang.MissingMethodException: No signature of method: org.eclipse.yasson.internal.JsonBinding.writeObject() is applicable for argument types: (com.mycompany.myapp.web.rest.vm.LoginVM, StringWriter) values: [LoginVM{username='admin', rememberMe=null}, ]

RestAssured 4.2.0 comes with JsonB support. https://github.com/rest-assured/rest-assured/pull/1257
