  Scenario Outline: Failed Login                # features/login.feature:6
    Given I am not authenticated                # features/login.feature:7
    When I go to /login                         # features/login.feature:8
    And I fill in "login" with "<mail>"         # features/login.feature:9
    And I fill in "password" with "<password>"  # features/login.feature:10
    And I press "Log In"                        # features/login.feature:11
    Then the login request should fail          # features/login.feature:12
    Then I should see an error message          # features/login.feature:13
