How to construct empty Array list in Json using Rest Assured

I am serializing the Json from POJO class. I want to send empty array in Request but when i pass null or empty value to the properties in pojo class, i am getting [""] in array list instead of []

Expected:  "Key": []

But I am getting: "Key":[""]

My pojo:

public class Sample {

    private List<String> Key=null;
}

Test data builder class:

Sample s = new Sample();
s.Key = ""; // Even if i give null here, i am getting null at the json payload.

Pls suggest ways to construct an empty array for Key as below.

{
"Key": []
}
Solution

  • Just initialize new ArrayList, like this.

    Sample s = new Sample();
s.Key = new ArrayList<>();
