# Requires supporting ruby files with custom matchers and macros, etc, in
# spec/support/ and its subdirectories. Files matching `spec/**/*_spec.rb` are
# run as spec files by default. This means that files in spec/support that end
# in _spec.rb will both be required and run as specs, causing the specs to be
# run twice. It is recommended that you do not name files matching this glob to
# end with _spec.rb. You can configure this pattern with the --pattern
# option on the command line or in ~/.rspec, .rspec or `.rspec-local`.
#
# The following line is provided for convenience purposes. It has the downside
# of increasing the boot-up time by auto-requiring all files in the support
# directory. Alternatively, in the individual `*_spec.rb` files, manually
# require only the support files necessary.

  # [@jeremyf] <2022-02-07 Mon> :: In https://github.com/forem/forem/pull/16423 we were discussing
  #
  # There are three use cases to consider regarding the Listing feature:
  #
  # - Those who will have it enabled (e.g., DEV.to), if they so choose to enable the flag.
  # - Those who will not have it enabled (e.g., those that do nothing)
  # - Our test suite
  #
  # We want our test suite to behave as though it's enabled by default.  This rspec configuration
  # helps with that.  I envision this to be a placeholder.  But we need something to get the RFC out
  # the door (https://github.com/forem/rfcs/issues/291).
