Feature: Login
  Background:
    Given a user "testuser" with password "testpassword" exists

  Scenario: Successful Login
    Given I have all cookies cleared
    And I go to the start page
    When I enter "testuser" in the field "username"
    And I enter "testpassword" in the field "password"
    And I hit the "login" button
    Then the HTTP response code MUST be 200 "Ok"
    And the response MUST set a cookie with the JWT

Feature: Login

    Given a user "testuser" with password "testpassword" exists

  Scenario:
    Given I am currently not logged in
    When logging in with username "testuser" and password "testpassword"
    Then login MUST be successful
