How to set root if the response has two arrays in rest assured

Question

My API's response is something like this: JSON

"Catalog": 
[
        {
            "longDescription": "some long description",

        "Price": [
            {
                "priceValue": "60.0",
            }
        ],
        "name": "some name",
       and so on.

I want to get the price value and I am using JsonPathEvaualtor.setRoot("catalog")? do I use ("price") or is there something else used to traverse inside catalog array then inside that price array.

Answer 1

So basically the parsing structure of your json with rest assured is this to get "Price" array

List<Map<String, List<Map<String, String>>>>

Here is the solution

First set the root to catalog

JsonPathEvaualtor.setRoot("catalog")

To get the priceValue correspodning to the first map element in the array, do the following

response.jsonPath().getList("$").getMap("Price").get(0).getMap(0).getString("priceValue");

I am not sure whether the above code is without bugs as I have not executed it. Hope it gives you some idea about the direction of the solution

Answer 2

I would suggest de-serialize your json to a POJO and then use the getters to extract information from the json especially when the json is little complicated [having lists and nested objects].

RestAssured provides option for de-serialization. There are other libraries like gson and jackson for the same. Personally I find gson much easy to use. Have a look at the below links for more insights.
