Make after_commit callbacks fire in tests for Rails 3+ with transactional_fixtures = true.

Deprecation this is no longer needed on rails 5.0+ rails/rails#18458

Install

gem install test_after_commit

# Gemfile (never include in :development !)
gem 'test_after_commit', :group => :test

Usage

Test that the methods get called or the side-effect of the methods, something like:

class Car < ActiveRecord::Base
  after_commit :foo, :on => :update

  def foo
    $foo = 1
  end
end

...

it "sets $foo on commit" do
  $foo.should == nil
  car.save!
  $foo.should == 1
end

Temporary disable after commit hooks

In your test_helper, you can specify the default

TestAfterCommit.enabled = true

Then use blocks in your tests to change the behavior:

TestAfterCommit.with_commits(true) do
  my_tests
end

TestAfterCommit.with_commits(false) do
  my_tests
end

TIPS

• hooks do not re-raise errors (with or without this gem) use after_commit_exception_notification
