40. Convert JSON Array API Response to Java List to extract values in Rest Assured

Hey Guys,
We need to perform assertions of values in API Response. To assert that a specific value from the response body we need to extract them. There are multiple ways to do so. We have already learned to convert a simple JSON object to a Java Map and extracted value for any field easily.

In this video, we will convert or deserialize the JSON Array response to Java List.

Hello Sir

Your explanation for Rest assured is awesome.
Please cover auth 0.1, 0.2

Instead of sysout we can print the response using log().all() method and we can use matchers methods to validate the response. Can you pls show the video related to that and by using Jackson data binder as well for serialization and deserialization

Hello Sir, I am getting the below error while using list to store the array response .
java.lang.Exception: Cannot parse content to interface java.util.List because no content-type was present in the response and no default parser has been set.

You can specify a default parser using e.g.:

RestAssured.defaultParser = Parser.JSON;

Kindly Help

I want to fetch amount which is inside another json nested Jason .... [{ "intialAmount" : { amount : 1.0, "currency" : "USD" }}].... How to write code for this? or response.get(amount)? In both the cases I'm getting null can you please help? Thanks in advance... I want to validate amount from the response with amount I'm passing while creating the transaction.. So passed amount should be stored properly.
