Feature: Font selection

In order to have better using experience,
As a reader and writer,
I want to change or disable the fonts for interface and content.

In addition the user is provided live preview feature: changes are applied
immediately when selection is made. Changes can either be applied or discared
for easy testing.

Background:
  Given I am logged in
    And I set "German" as the interface language
    And the content language is "English"
    And I inspect current fonts

Scenario: Discarding live preview of content font
  When I open "Fonts" panel of language settings
    And I select "OpenDyslexic" font for the content language for the live preview
    And I close the panel to discard the changes
  Then the active content font must be the same as font prior to the preview
    # System is the default value for English and German
    And the selected content font must be "system"

Scenario: Discarding live preview of interface font
  When I open "Fonts" panel of language settings
    And I select "OpenDyslexic" font for the interface language for the live preview
    And I close the panel to discard the changes
  Then the active interface font must be the same as font prior to the preview
    # System is the default value for English and German
    And the selected interface font must be "system"

Scenario: Applying the live preview of interface font
  When I open "Fonts" panel of language settings
    And I select "OpenDyslexic" font for the interface language for the live preview
    And I apply the changes
  Then the interface font must be changed to the "OpenDyslexic" font
