Subject: selftests: forwarding: Skip test when no interfaces are specified
From: Ido Schimmel <idosch@xxxxxxxxxx>
commit d72c83b1e4b4a36a38269c77a85ff52f95eb0d08 upstream.
As explained in [1], the forwarding selftests are meant to be run with
either physical loopbacks or veth pairs. The interfaces are expected to
be specified in a user-provided forwarding.config file or as command
line arguments. By default, this file is not present and the tests fail:
# make -C tools/testing/selftests TARGETS=net/forwarding run_tests
[...]
TAP version 13
1..102
# timeout set to 45
# selftests: net/forwarding: bridge_igmp.sh
# Command line is not complete. Try option "help"
# Failed to create netif
not ok 1 selftests: net/forwarding: bridge_igmp.sh # exit=1
[...]
Fix by skipping a test if interfaces are not provided either via the
configuration file or command line arguments.
# make -C tools/testing/selftests TARGETS=net/forwarding run_tests
[...]
TAP version 13
1..102
# timeout set to 45
# selftests: net/forwarding: bridge_igmp.sh
# SKIP: Cannot create interface. Name not specified
ok 1 selftests: net/forwarding: bridge_igmp.sh # SKIP
