#
# This test starts NetworkManager stub service in a user D-Bus session,
# and runs nmcli against it. The output is recorded and compared to a pre-generated
# expected output (clients/tests/test-client.check-on-disk/*.expected) which
# is also committed to git.
#
###############################################################################
#
# HOWTO: Regenerate output
#
# When adjusting the tests, or when making changes to nmcli that intentionally
# change the output, the expected output must be regenerated.
#
# $ make install
# # (step not required every time)
# # The test also compare the translated output, hence, the translation
# # file must be installed at the configured --prefix.
# # You don't need to type `make install` every time, but a suitable version
# # of translations must be installed. In practice, the tests only care about
# # Polish (pl) translations.
# # The important part is that translations work. Test
# # $ LANG=pl_PL.UTF-8 ./clients/cli/nmcli --version
# # also ensure that `locale -a` reports the Polish locale.
# $ NM_TEST_REGENERATE=1 make check-local-clients-tests-test-client
# # Set NM_TEST_REGENERATE=1 to regenerate all files.
# $ git diff ... ; git add ...
# # (optional step)
# # Inspect what changed, and whether it makes sense. Then commit changes
# # to git.

# (optional) The build dir. Optional, mainly used to find the nmcli binary (in case
# ENV_NM_TEST_CLIENT_NMCLI_PATH is not set.

# In particular, you can test also a nmcli binary installed somewhere else.
ENV_NM_TEST_CLIENT_NMCLI_PATH = "NM_TEST_CLIENT_NMCLI_PATH"
# (optional) The test also compares tranlsated output (l10n). This requires,
# that you first install the translation in the right place. So, by default,
# if a test for a translation fails, it will mark the test as skipped, and not
# fail the tests. Under the assumption, that the test cannot succeed currently.
# By setting NM_TEST_CLIENT_CHECK_L10N=1, you can force a failure of the test.

# on disk with the expected output.

# only for debugging, to correlate the expected output with the test.
