Installation Steps

[bmulholland]

It wasn't obvious how to install & use this, so recording my steps here:

1. Add to Gemfile for test and development groups: gem "turbo_test"
2. Add test env number to database.yml, just like with parallel_tests: https://github.com/grosser/parallel_tests#add-to-configdatabaseyml
3. Set that env for each worker by creating a new file turbo_test.rb at the project root, with (via Possible incompatibility w/ other gems that work using "parallel_tests" #4 (comment)):

ENV["RAILS_ENV"] = "test"

worker do |index|
  index = index + 1
  ENV['TEST_ENV_NUMBER'] = index == 1 ? "" : index.to_s

  # create a database for each worker
  system("bin/rails", "db:drop", "db:create", "db:migrate")
end

4. Run with bundle exec turbo_test

Yes, that looks acceptable to me. Did it work as expected?

Not yet, because databases did not exist. See #8 for steps necessary before turbo_test can be run.
