devise-async & sidekiq - RSpec integration spec fails - ruby-on-rails

Question

I have the following integration tests written for my application's Devise based authentication:
# password_resets_spec.rb
require 'spec_helper'
describe "PasswordResets" do
it "emails user when requesting password reset" do
user = FactoryGirl.create(:user)
reset_email # or else we'll have the confirmation email in the last assertion
visit new_user_session_path
click_link "password"
fill_in "Email", with: user.email
click_button "Send"
current_path.should eq(new_user_session_path)
page.should have_content "Will receive"
last_email.to.should include(user.email)
end
it "doesn't email invalid user when requesting password reset" do
user = FactoryGirl.create(:user)
reset_email # or else we'll have the confirmation email in the last assertion
visit new_user_session_path
click_link "password"
fill_in "Email", with: 'nobody#example.com'
click_button "Send"
current_path.should eq(user_password_path)
page.should have_content "correct"
last_email.should be_nil
end
end
and:
# registers_spec.rb
require 'spec_helper'
describe "Registers" do
it "should inform the user to confirm account" do
user = FactoryGirl.build(:user)
visit new_user_registration_path
fill_in "Username", with: user.username
fill_in "Email", with: user.email
fill_in "Password", with: user.password
fill_in "Confirm password", with: user.password
click_button "Send"
current_path.should eq(root_path)
page.should have_content "You have been sent"
last_email.to.should include(user.email)
end
end
I am using Sidekiq for background jobs and last_email and reset_email come from the following module:
module MailerMacros
def last_email
ActionMailer::Base.deliveries.last
end
def reset_email
ActionMailer::Base.deliveries.clear
end
end
All three of these specs work fine when deactivating devise-async on the User model. When I switch it on, the password reset specs run OK but the register one complains about last_email being nil and I don't understand why. Is the confirmation mail sent out somehow differently compared to the password reset ones?
Note that I have the require 'sidekiq/testing/inline' line in my spec_helper.rb file so that the email sending is done instantaneously and config.action_mailer.delivery_method = :test is set for my test environment so that no actual email sending is taking place.

Answer 1

I have solved the issue with mhfs' help. The problem was that I had config.use_transactional_fixtures set to true in spec_helper.rb and because of this users were created in a transaction and the after_commit hook which would send the email was never called. Password resets apparently didn't run inside transactions, that's why they worked.
So I had to switch use_transactional_fixtures off and use database_cleaner to keep my database tidy.
Here's what I had to modify:
Add gem 'database_cleaner' to my Gemfile.
Obviously modify spec_helper.rb:
config.use_transactional_fixtures = false
Add the following to spec_helper.rb:
config.before(:each) do
with_transaction_callbacks = example.metadata[:with_transaction_callbacks]
if with_transaction_callbacks
DatabaseCleaner.strategy = :truncation
else
DatabaseCleaner.strategy = :transaction
end
DatabaseCleaner.start
end
config.after(:each) do
DatabaseCleaner.clean
end
And lastly redo my block in registers_spec.rb to read:
describe "Registers" do
it "should inform the user to confirm account", with_transaction_callbacks: true do
[ --- 8< snip --- ]
end
end
The magic happens in the second line.
