REST Assured Tutorial 13 – Writing Response in a Text File

Last updated on December 12th, 2019 at 02:59 pm

As a part of End to End REST Assured Tutorial , in this post We will learn to write response to an external text file in Rest Assured.

You may required to save API response in to an external file like text or JSON etc file for future reference or as a proof. In this post, we will concentrate on saving response in a text file.

Rest Assured provides below methods to get response as:-

  1. As byte array :- asByteArray()
  2. As input stream :- asInputStream()
  3. As string :- asString()

All above methods output can be used to write in to text file.

Rest Assured Code:-

Output:-

Refresh the project folder if you are using Eclipse. You should see three files as below:-

Open a file you should see it has stored response as below:-

You may be thinking which way is more optimal if you want to write in to a file. If you notice when we get response as String or inputStream , we must need to convert them to Byte array before writing in to a file. In third way we are directly getting Byte Array. So third way is more optimal.
