I didn't notice this before, but the first two lines of the backtrace reveal the problem. The `and_raise` method only works with an error class if that class has a 0-arg initializer [1]. ActiveRecord::StaleObjectError's initializer requires two arguments [2]. This changed between 3.1 and 3.2 [3,4]. I added a placeholder for a feature request to improve the error messaging in rspec-mocks [5]. To fix the problem (with or without helpful error messages from rspec), it's up to you to change act.stub(:update_attributes).and_raise(ActiveRecord::StaleObjectError) to something like act.stub(:update_attributes).and_raise(ActiveRecord::StaleObjectError.new(act, :update)) HTH, David [1] http://rubydoc.info/gems/rspec-mocks/RSpec/Mocks/MessageExpectation#and_raise-instance_method [2] https://github.com/rails/rails/blob/master/activerecord/lib/active_record/errors.rb#L101-112 [3] https://github.com/rails/rails/commit/410fa4cf [4] https://github.com/rails/rails/commit/c6f0461 [5] https://github.com/rspec/rspec-mocks/issues/99 > > The line in the controller that bombs out (about 7 lines down in the > trace) is: > > if @act.update_attributes params[:act] > flash.now.notice = "Act was updated.
