Ruby on rails: breaking down a large test_helper.rb

We have a pretty large test/test_helper.rb file, which does quite a few unrelated things. Is there a "Rails way" to decompose it into subfiles, stored in some conventional location?

I tried searching the official docs, but couldn't find anything. Any help appreciated!

Solution

  • We do this in our spec/spec_helper.rb (using RSpec rather than Minitest, but the same principle should apply):

    Dir["#{File.dirname(__FILE__)}/support/**/*.rb"].sort.each do |file|
  require file
end

    We then have different configuration files such as spec/support/vcr.rb, spec/support/redis.rb, etc.

    edit: This actually came from the file generated by rspec-rails. Here is that line as of RSpec 3.9:

    Dir[Rails.root.join('spec', 'support', '**', '*.rb')].each { |f| require f }
