REST Assured Tutorial 9 – Let’s Write First POST Request in REST Assured

As a part of End to End REST Assured Tutorial , in this post We will write first POST request in REST assured.

To learn what is POST request and how can you hit a POST request in Postman tool, must refer this post.

We will automate a POST request named “GetAuth” from Restful Booker. We will perform some validations like status code as well.

GetAuth API takes body as below where you need to pass username and password. If you pass credentials correctly, you will get token else error message.

Let’s start writing a POST request in REST Assured using both BDD and Non-BDD style. We will see multiple ways of writing same test as well.

Passing body to POST request:-

We know that we need to pass a payload ( JSON or XML) to POST request. REST Assured makes it very handy to pass body to request. We can pass body as a String or a JSON file or a XML file or a Java Object or a byte array. We will see all ways in upcoming posts but as of now we will pass body as a String.

    Thank you in advance

    1. Hey, because example APIs returns 200 on successful post request. It is completely dependent on developers what status code they return. If they return 201, we need to assert as 201.
