It now captures the full initial cache state before adding\ntest rules and verifies that the cache state remains unchanged after adding\nunsupported rules (keeping the intent of the test intact).\n\nSigned-off-by: Matteo Perin <matteo.perin@canonical.com>\n---\n tests/system-route.at | 42 ++++++++++++++++++++----------------------\n 1 file changed, 20 insertions(+), 22 deletions(-)", "diff": "diff --git a/tests/system-route.at b/tests/system-route.at\nindex 0b4b4b7e9..3ff14453b 100644\n--- a/tests/system-route.at\n+++ b/tests/system-route.at\n@@ -343,18 +343,15 @@ on_exit 'ip link del p1-route'\n AT_CHECK([ip tuntap add name p1-route mode tap])\n AT_CHECK([ip link set p1-route up])\n \n-dnl Check there are no non-standard rules cached in OVS.\n-AT_CHECK([ovs-appctl ovs/route/rule/show], [0], [dnl\n-Cached: 0: from all lookup local\n-Cached: 32766: from all lookup main\n-Cached: 32767: from all lookup default\n-])\n-AT_CHECK([ovs-appctl ovs/route/rule/show -6], [0], [dnl\n-Cached: 0: from all lookup local\n-Cached: 32766: from all lookup main\n-])\n-\n-dnl Add unsupported rules to kernel.\n+dnl Capture initial cache state before adding any rules.\n+AT_CHECK([ovs-appctl ovs/route/rule/show | sort], [0], [stdout])\n+AT_CHECK([mv stdout initial_v4])\n+AT_CHECK([ovs-appctl ovs/route/rule/show -6 | sort], [0], [stdout])\n+AT_CHECK([mv stdout initial_v6])\n+\n+dnl Add various unsupported rules.
