Mongoid

For usage with mongoid, modify /spec/spec_helper.rb. Remove these lines:

ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)
..
config.fixture_path = "#{::Rails.root}/spec/fixtures"
..
config.use_transactional_fixtures = true

And add to /spec/spec_helper.rb, below Rspec.configure

config.before(:suite) do
  DatabaseCleaner[:mongoid].strategy = :truncation
end

config.before(:each) do
  DatabaseCleaner[:mongoid].start
end

config.after(:each) do
  DatabaseCleaner[:mongoid].clean
end
