REST Assured Tutorial 66 – How To Parse A JSON Array Response To A Java List In Rest Assured?

Introduction

As a part of the End to End REST Assured Tutorial, in this post, we will learn to parse a JSON Array response to a Java List in Rest Assured.

It is not always necessary to convert the response to a POJO class instance to fetch values. We can cast or convert a JSON Array response into a Java List directly. It is useful if you do not use Pojo classes.

We are using the below version of Rest Assured:-

Parse JSON Array Response to Java List

Once a response is returned and if it is a JSON array then we can parse them as a List. There is a method called as() which takes a TypeRef reference to support classes with generics. For example – A JSON Array can be represented as a List<Object>. To cast Json Array response in such type we need to use as() method with TypeRef. TypeRef is an abstract class that is used to specify generic type information when de-serializing a response.
