From 1056691b26809e838da67bc2a61761017d20cfda Mon Sep 17 00:00:00 2001 From: David Ahern Date: Tue, 13 Feb 2018 08:37:34 -0800 Subject: [PATCH] selftests: fib_tests: Make test results more verbose fib_tests.sh is failing in a VM: $ fib_tests.sh Running netdev unregister tests PASS: unicast route test PASS: multipath route test Running netdev down tests PASS: unicast route test PASS: multipath route test Running netdev carrier change tests PASS: local route carrier test FAIL: unicast route carrier test The last test corresponds to fib_carrier_unicast_test which 12 places that could be failing. Be more verbose in the output so a failure is easier to track down and separate test setup failures with set -e and set +e pairs. With the verbose logging it is easier to see which checks are failing: $fib_tests.sh Single path route carrier test .... Carrier down IPv4 fibmatch [ OK ] IPv6 fibmatch [ OK ] IPv4 linkdown flag set [FAIL] IPv6 linkdown flag set [FAIL] Second address added with carrier down IPv4 fibmatch [ OK ] IPv6 fibmatch [ OK ] IPv4 linkdown flag set [FAIL] IPv6 linkdown flag set [ OK ] Signed-off-by: David Ahern Signed-off-by: David S.
