Except those we've just discussed (which I'm working on), these are the outstanding issues (I re-ran all the tests)...

http://localhost/composr/_tests/index.php?id=unit_tests/basic_code_formatting&close_if_passed=1
Has trailing whitespace in themes/default/javascript/CMS_VIEWS.js

http://localhost/composr/_tests/index.php?id=unit_tests/config&close_if_passed=1
use_monochrome_icons must be accessed as a theme option (.php): adminzone/pages/modules/admin_svg_sprites.php

http://localhost/composr/_tests/index.php?id=unit_tests/cqc_adminzone&close_if_passed=1
WARNING "adminzone/pages/modules/admin_svg_sprites.php" 214 75 PHP: Could not find function 'simplexml_load_string

http://localhost/composr/_tests/index.php?id=unit_tests/sitemap&close_if_passed=1
No help defined for SVG sprites (adminzone:admin_svg_sprites)

template_previews not only fails due to a few issues of yours. This takes a long time to run, and it creates files in _tests/screens_tested/. It's re-entrant, so if it times out you can refresh.

All tests now passing as of writing.
