ruby on rails - RSpec: check if any model has been saved -

in rails application i've created method creates model hierarchy basing on json data. i'd assure method not save database. know can write test like:

expect { importer.import(json) }.not_to change(model1, :count) expect { importer.import(json) }.not_to change(model2, :count) # etc.

but i'd in more generic way. there method in rspec check if model had been saved during test?

not sure if rspec help this, quick manual trip database might job?

[model1, model2].each |model| model.where('updated_at > ?', time.now - 2.seconds).count.should eq 0 end
