# Coverage report: runs the test suite and collects coverage information.
# use llvm-cov to build and collect coverage and outputs in a format that
# is compatible with codecov.io
#
# note that codecov as of v4 requires that CODECOV_TOKEN from
#
# https://app.codecov.io/gh/<user or org>/<project>/settings
#
# is set in two places on your repo:
#
# - https://github.com/jonhoo/guardian/settings/secrets/actions
# - https://github.com/jonhoo/guardian/settings/secrets/dependabot
#
# (the former is needed for codecov uploads to work with Dependabot PRs)
#
# PRs coming from forks of your repo will not have access to the token, but
# for those, codecov allows uploading coverage reports without a token.
# it's all a little weird and inconvenient. see
#
# https://github.com/codecov/feedback/issues/112
