A spec helper file for managing database cleaner configuration

spec_helper.rb

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'capybara/rspec'

RSpec.configure do |config|

  config.use_transactional_fixtures = false
  config.treat_symbols_as_metadata_keys_with_true_values = true

  # before everything
  config.before(:suite) do
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.clean_with(:truncation)
  end

  # second on feature specs, first otherwise
  config.before(:each) do
    DatabaseCleaner.start
  end

  # third on feature specs, second/last otherwise
  config.after(:each) do
    p cleaner_strategy
    DatabaseCleaner.clean
  end

  # first on feature specs
  config.prepend_before(:each, :type => :feature) do
    DatabaseCleaner.strategy = :truncation
  end

  # last/fourth on feature specs
  config.append_after(:each, :type => :feature) do
    DatabaseCleaner.strategy = :transaction
  end

end

# how to get at what strategy is active, if you like
def cleaner_strategy
  active_record_cleaner.instance_variable_get(:@strategy).class
end

def active_record_cleaner
  DatabaseCleaner.instance_variable_get(:@cleaners)[[:active_record, {}]]
end

Note, the various befores and afters don't seem to respect order in Rspec 1.3.2.
