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