A standard set of fixtures for unit tests?

What you get when Moodle in installed

When Moodle is installed, you don't just get empty database tables in the database, you also get some data created in some of the tables. The following is what I get from a fresh install of HEAD on Postgres using

SELECT relname, reltuples FROM
pg_class
WHERE
relname LIKE 'mdl_%'
AND relkind = 'r'
AND reltuples > 0
ORDER BY reltuples DESC

Table	rows
mdl_role_capabilities	600
mdl_capabilities	236
mdl_config	205
mdl_log_display	104
mdl_survey_questions	73
mdl_config_plugins	35
mdl_block	31
mdl_mnet_rpc	17
mdl_mnet_service2rpc	17
mdl_modules	15
mdl_role_allow_assign	13
mdl_user_preferences	8
mdl_role_allow_override	7
mdl_role	7
mdl_block_instance	6
mdl_survey	5
mdl_quiz_report	4
mdl_mnet_service	4
mdl_message_providers	4
mdl_context	3
mdl_message_processors	3
mdl_mnet_host	2
mdl_user	2
mdl_mnet_application	2
mdl_events_handlers	2
mdl_cache_flags	1
mdl_course_categories	1
mdl_role_assignments	1
mdl_course	1

Interpreting that, we have

• Version information for all installed plugins (and Moodle itself).
• Defaults for all the config variables.
• The standard roles and their capabilites
• The Admin user.
• The Guest user.
• The Miscellaneous category.
• The site course.
• The log_display information.
• Configuration of the messaging system.
• Some mnet stuff.
• Some survey module stuff.
