Question

I'm using rest assured for Rest api testing with the help of POJO classes like getter and setter methods to set the values but i'm stuck with array list in between rest request,please any one provide proper code to get exact below request to post using rest assured.

Request:

{
"firstName":"SuryaNAMASKARAM",
"lastName":"mangalam",
"mobileNo" :4954758490,

"paymentDetail" :
[{"paymentType":"CASH","No":"3519000012","Date":"16-06-2018","amount":"100.00"}]
}

}

Test Class:

import java.util.ArrayList;
import java.util.List;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

        example.setLandmark("Test");        

        List<PaymentDetail> data = new ArrayList<PaymentDetail>();

        PaymentDetail paymentDetail = new PaymentDetail();
        paymentDetail.setAmount("999.00");
        data.add(paymentDetail);            

        JSONObject jsonObject = new JSONObject(example);

        JSONArray jsonArray = new JSONArray(data);
        jsonArray.put(data);

        System.out.println(jsonArray.put(data));        

    }

Answer 1

In your test class, what you must do is separate the test data creation to a different class and pass that as data provider to your test method. This is from design point of view.

Coming to your problem: You are already using gson, why are you constructing a JSONObject. Instead do something like below;

Gson gson = new Gson(); 
String _my_obj = gson.toJson(example);

Hope this is what you are looking for.
