If you preload your test database with all fixture data via the rake task:
bin/rails db:fixtures:load
``
And set self.pre_loaded_fixtures to true:
class ActiveSupport::TestCase
self.pre_loaded_fixtures = true
self.use_transactional_tests = true # the default
fixtures :all
end
``
Would you expect the fixtures to be deleted and reinserted on every test run (caused by ActiveRecord::FixtureSet.create_fixtures – the same code exercised by the rake task)? Given the documentation on Transactional Tests, I’d imagine this to be unexpected behaviour but, regardless of options configured, fixture data is always reinstalled by the fixtures :all call.
