# 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 (src/tests/client/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.
#
# For that, you'd setup your system correctly (see SETUP below) and then simply:
#
#  $ meson -Ddocs=true --prefix=/tmp/nm1 build
#  $ ninja -C build
#  $ ninja -C build install
#  $ NM_TEST_REGENERATE=1 ninja -C build test
#  $ git diff ... ; git add ...
#    # The previous step regenerated the expected output. Review the changes
#    # and consider whether they are correct. Then commit the changes to git.
#
# Beware that you need to install the sources, and beware to choose a prefix that doesn't
# mess up your system (see SETUP below).
#
# SETUP: For regenerating the output, the translations must work. First
# test whether the following works:
#
#  1) LANG=pl_PL.UTF-8 /usr/bin/nmcli --version
#    # Ensure that Polish output works for the system-installed nmcli.
#    # If not, you should ensure that `locale -a` reports the Polish
#    # locale. If that is not the case, how to enable the locale depends on
#    # your distro.
#    #
#    # On Debian, you might do:
#    #   sed -i 's/^# \(pl_PL.UTF-8 .*\)$/\1/p' /etc/locale.gen
#    #   locale-gen pl_PL.UTF-8
#    # On Fedora, you might install `glibc-langpack-pl` package.
#
#  2) LANG=pl_PL.UTF-8 ./src/nmcli/nmcli --version
#    # Ensure that the built nmcli has Polish locale working. If not,
#    # you probably need to first `make install` the application at the
#    # correct prefix. Take care to configure the build with the desired
#    # prefix, like `meson setup build --prefix=/opt/tmp`. Usually, you want to avoid
#    # using /usr as prefix, because that might overwrite files from your
#    # package management system.

# Environment variables to configure test:

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

# in build dir.
ENV_NM_TEST_CLIENT_CLOUD_SETUP_PATH = "NM_TEST_CLIENT_CLOUD_SETUP_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.

# Regenerate the .expected files. Instead of asserting, rewrite the files
# on disk with the expected output.

# whether the file location should include the line number. That is useful
# only for debugging, to correlate the expected output with the test.
# Obviously, since the expected output is commited to git without line numbers,
# you'd have to first NM_TEST_REGENERATE the test expected data, with line
# numbers enabled.
