Rails < 5: How to get after_commit callbacks fired in tests

If you use transactional_fixtures or the database_cleaner gem with strategy :transaction, after_commit callbacks will not be fired in your tests.

Rails 5

Rails 5 has a fix for this issue and no further action is needed.

Rails 3+

Add the gem test_after_commit to your test group in the Gemfile and you are done. You don't need to change the database strategy to deletion (which might lead to longer test runs).

Note:

Most often a after_commit is the only right choice. Sending emails, performing async sidekiq workers and many things more are kind of broken with an after_save callback.

If you replace an after_save callback with an after_commit callback this list might help you to fix your code afterwards:

  • attribute_changed? will return true in the after_save callback and false in the after_commit callback. Use something like previous_changes.key?(:attribute) instead.
