[rspec-users] Transactional fixtures for Gem (not Rails) development

[medihack]

Hello.

Is it possible to also use the transactional examples feature for gem
(not Rails) development. It seems that one has to require "rspec-
rails", but I still can't get it to work.

I added this to my spec_helper.rb:
RSpec.configure do |config|
config.use_transactional_fixtures = true
end

And also required:
require 'rubygems'
require 'bundler'
require 'logger'
require 'active_record'
require 'rails'
require 'rspec-rails'
require 'active_support'

But I get that error when running a test:
undefined method `use_transactional_fixtures=' for
#<RSpec::Core::Configuration:0xb706d0bc> (NoMethodError)
although I required rspec-rails and rails as mentioned above

Is it simply not possible to use transactional examples for gem
development?

Best regards,
Kai

Nope. That feature is not implemented in RSpec, it is implemented in Rails. RSpec just provides access to it.

You can (and probably should) use the database_cleaner gem. Directions for using it with RSpec are at the bottom of the README on https://github.com/bmabey/database_cleaner.
