Scenario: Create a programmer
Given I have the payload:
"""
{
  "name": "John",
  "lastname" : "Doe",
  "username": "john.doe",
  "email": "john.doe@email.com",
  "password": "password",
  "birth": "10/10/1970",
  "type": "normal"
}
"""
When I request "POST" "/users"
Then the response status code should be "201"
And the "Location" header should be "http://api.localhost.dev/users/john.doe"

/**
 * @BeforeScenario
 */
public function clearData()
{
   $this->_service->deleteUsers();
}
