Problem with checking values of JSON array using Rest Assured

Question

I'm trying to add some tests with Rest-Assured to my application, but I can't figure out how to assert some nested values. The error message is :

Expected: (a collection containing "json") Actual: [[json, spring, gulp, path etc...]]

Here is the code :

 when().
       get("/api/personsByID/{id}/{count}", 262, 2).
       then().
       statusCode(200).
       body("personDependencies.name", hasItems("json"));

And here is the JSON file that is returned by rest controller:

[
    {
        "id": 346,
        "verified": true,
        "displayName": "eda656a2c3cb59ae840e40a28ba4ab50bfb9de0185abcb901c6af6dc59d6668f",

            }
        ],
        "personDependencies": [
            {
                "name": "json"

I have no idea how to make proper assertions, any help would be great. Thanks!

See github.com/rest-assured/rest-assured/issues/805 for examples, you are dealing with an array and need to select a specific instance or do the assert for all instances. — ewramner

I have tried: find body(" find {it.id=='346'}.personDependencies.name", hasItems("json", "jackson")) but this returns a null — bioinformatic98

As you can see, it is only one id in the output JSON file, but what I want to achieve is to be able to select one of the objects with for example id=400 and make assertion if that object has certain values in personDependencies. I have tried: find body(" find {it.id=='346'}.personDependencies.name", hasItems("json", "jackson")) but this returns a null — bioinformatic98

If I am reading your question right you need to check if a certain values are present in a list that is returned for a particular ID

The below should work for you

given().when().get().then().body("find {it.id == 346}.personDependencies.name", hasItems("json", "jackson"));

The first problem you don't need to check the presence of an item with hasItems, you should use hasItem

when().
       get("/api/personsByID/{id}/{count}", 262, 2).
       then().
       statusCode(200).
       body("personDependencies.name", hasItem("json"));

Then if you need to add more message to the assertion when the test fails you can do such way:

 when().
        get("/api/personsByID/{id}/{count}", 262, 2).
        then().
        statusCode(200).
        body("personDependencies.name",  describedAs("Array not containing the provided item",hasItem("json")));

In your case you can validate such a way:

when().
       get("/api/personsByID/{id}/{count}", 262, 2).
       then().
       statusCode(200).
       body("personDependencies[*].name", hasItem("json"));

"hasItems" is not causing problems.

And what is the problem?

I have to select a specific instance in my array for the one specific user as @ewramner suggested above, but I do not know how.

Wilfred Clement's answer is great. Just want to add 1 more example for better understanding concept and syntax. Use next syntax if you have to make similar search in some array which is not on 'root' level of JSON:

.body("problems.find {it.property == 'boardUrl'}.details", is("size must be between 1 and 256"))

This path is created for the JSON structure below:

{
"title": "Bad Request",
"status": 400,
"problems": [
    {
        "property": "tag",
        "value": "too-big-tag-value",
        "details": "size must be between 1 and 10"
    },
    {
        "property": "name",
        "value": "Very big name for testing purposes",
        "details": "size must be between 1 and 20"
    }
  ]
}
