1# This file was generated by the `rspec --init` command. Conventionally, all
  2# specs live under a `spec` directory, which RSpec adds to the `$LOAD_PATH`.
  3# The generated `.rspec` file contains `--require spec_helper` which will cause
  4# this file to always be loaded, without a need to explicitly require it in any
  5# files.
  6#
  7# Given that it is always loaded, you are encouraged to keep this file as
  8# light-weight as possible. Requiring heavyweight dependencies from this file
  9# will add to the boot time of your test suite on EVERY test run, even for an
 10# individual file that may not need all of that loaded. Instead, consider making
 11# a separate helper file that requires the additional dependencies and performs
 12# the additional setup, and require it from the spec files that actually need
 13# it.
