Rest assured verify that a JSON body contains all Strings from a List

Question

So basically, i have constructed a list that contains Strings of a JSON object's body field names.

Something like this:

List<String> fieldNames = new ArrayList<String>();

Then I have used Rest-assured to GET a response which is in JSON format something like this:

{
"id": 11,
"name": "CoolGuy",
"age": "80",
}

So my list contains "id", "name" and "age". How can i verify that JSON fields match those strings in my list. WITHOUT depending on their order.

I only know how to verify that it contains one String and here's the whole JUnit test method I used:

@Test
public void verifyJSONMatch() {
    given().auth().basic("user", "pass").when()
    .get(getRequestURL).then().body(containsString("id"));      
}

Any suggestions?

Answer 1

You can extract the response

ResponseOptions response = given().spec(request)
                    .get("/url_path");

And then parse a json

DocumentContext parsedJson = JsonPath.parse(response.getBody().asString());
            assertThatJson(parsedJson).field("['id']").isEqualTo("11");

Answer 2

It would probably be easiest to extract the response as a Java Object and then just assert that the extracted object is equal to the one you have above in JSON.

MyObject expectedObject = new MyObject(11, "CoolGuy", "80");
MyObject myObject = 
    given().auth().basic("user", "pass")
        .when().get(getRequestURL)
        .then().extract().response().as(MyObject.class);
assertEquals(expectedObject, myObject);

You could make the constructor for that whatever you want. I assume your object may be much more complicated than what is shown above. However, this is a much easier way to assert equality, and it is easily reusable.
