A faster way to deal with apartment in specs.

apartment_setup_database_test.rake

# This rake will setup the tenant like rails
# setup the test database.

Rake::Task['db:test:prepare'].enhance do
  # Connect in the test database.
  Rails.env = 'test'
  ActiveRecord::Base.establish_connection('test')

  Apartment::Tenant.drop('app') rescue nil
  Apartment::Tenant.create('appp')
end

spec_support_database_cleaner.rb

RSpec.configure do |config|
  config.before(:suite) do
    # Clean all tables to start
    DatabaseCleaner.clean_with :truncation
    # Use transactions for tests
    DatabaseCleaner.strategy = :transaction
    # Truncating doesn't drop schemas, ensure we're clean here, app *may not* exist
    Apartment::Tenant.drop('app') rescue nil
    # Create the default tenant for our tests
  end

  config.before do
    # Start transaction for this test
    DatabaseCleaner.start
    # Switch into the default tenant
    Apartment::Tenant.switch! 'app'
  end

  config.after do
    # Rollback tenant transaction
    Apartment::Tenant.switch('app') do
      DatabaseCleaner.clean
    end
    # Reset tentant back to `public`
    Apartment::Tenant.reset
    # Rollback transaction
    DatabaseCleaner.clean
  end
