# To get coverage
# On Local, default (HTML) output coverage is turned on with Ruby 2.7+:
#   bundle exec rspec spec
# On Local, all output formats with Ruby 3.0+:
#   COVER_ALL=true bundle exec rspec spec
#
# On CI, all output formats, but coverage only runs for the coverage workflow.
#   The ENV variable CI is always set,
#   and COVER_ALL, and CI_CODECOV, are set in the coverage.yml workflow only,
#   so coverage only runs in that workflow, and outputs all formats.
