Testing summary

Scope of Testing

In Scope

Testing efforts will be focused on confirming that the mechanism for selecting a theme(s), in this case, Compact Light and Compact Dark is working as expected across platforms. Also, it will be pay particular attention to the theme(s) itself and any obvious UI glitches introduced by a specific change.

Out of Scope

Only the new two themes mentioned above will be included in the testing efforts. Any others themes, are not going to be evaluated in order to find whether it satisfies the specified requirements or not.

Requirements for testing


Full testing will be done on following OSes:

  • Windows 7
  • Windwos 10
  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS
  • Mac OS X 10.11 or greater

About Compact Themes

Mozilla will ship two new lightweight themes starting with Firefox 53 by replacing compact theme with a light color scheme and a dark color scheme. These are based on the current Dev Edition theme and will be enabled by users in both about:addons#appearance and customization mode. The default theme will continue to be Australis.

Test Objectives

This section details the progression test objectives that will be covered. Please note that this is at a high level. For large projects, a suite of test cases would be created which would reference directly back to this master. This could be documented in bullet form or in a table similar to the one below.

Ref Function Test Objective Evaluation Criteria Test Type Owners
1 The mechanism for selecting Compact Themes is working properly
  • does an applied theme actually get applied (both in about:addons#appearance and customize mode)
  • does it persist on restart without any obvious flicker / flash of unstyled content
  • does the profile migration work properly - if you had the dark dev edition theme applied then it should apply the dark compact theme and if you had light dev edition theme applied it should apply the light compact theme
all scenarios provided must have the right expected result Manual Desktop Team
2 The theme itself
  • any obvious UI glitches introduced by a specific change
  • things to look at:
    • on mouseover, on mouseclick effects for buttons, menu entries, toolbar entries, site identity information, context menu
    • behaviour on different window sizes
    • if font used after the applied theme is still readable in application
    • the alignment of the text is proper
    • positioning of GUI elements for different screen resolution
there should be not UI issues on Compact Themes Manual Desktop Team

Testing approach

  • set up a smoke/acceptance suite that checks the core functionality associated to this feature, along with a few major UI components
  • set up an exploratory section within this suite that checks all the UI components


This section should contain links for builds with the feature:

The feature is available on Firefox 53 starting with 2017-01-15.

  • Links for Nightly builds - available since 15-01-2017 link
