Reqres_api_test.feature
Feature: Test Reqres Users API's With Rest Assured Library And Cucumber Framework
@SmokeTest
Scenario Outline: Reqres GET API test

Given the valid endpoint to fetch users
When the request is sent to the server with page number “<page>”
Then validate the response of the first user record having email as “<emailID>”

Examples:
|page|emailID |
| 2 |michael.lawson@reqres.in|
| 1 |george.bluth@reqres.in|

@SmokeTest
Scenario Outline: Reqres POST API test

Given the valid endpoint with payload to create a user
When the request is sent to the server
Then the new user must be created with the name “<username>”

Examples:
|username|
 | john |
