# This is not an ideal way of doing Rest testing because response is not outputted into browser in real life.

As a user
I should be able use web form for POST
#JSON
Scenario: Rest POST API - JSON response
Given I am on "/"
Then I should see "USER API"
When I follow "CREATE"
Then I should see "CREATE"
