[rspec-users] Issue when testing ActiveRecord after_commit callbacks

In an ActiveRecord model, I have an after_commit callback (:enqueue_job)
which places a job on my background processing queue (Sidekiq)
To test that the callback was firing when the database transaction
was committed, I was using:
object.should_receive(:enqueue_job) #should pass
Which seems to work. However, to test that the test was valid, I attempted
object.should_not_receive(:enqueue_job) #should fail
But this did not fail.
I tracked this down to ActiveRecord's
DatabaseStatements' commit_transaction_records method, which ends up eating
the RSpec Negative Method Expectation Exception (which fails fast)
If the negative method expectation did not fail fast, the test would
probably work, but is there a better pattern for testing after_commit logic?
(This was with rspec-mocks 2.10.1. use_transactional_fixtures was turned
off to enable the callback.)
