> Subject: [ovs-dev] [PATCH] tests: make ovn logical router test case more
> reliable
>
> The "ovn -- 1 HVs, 2 LSs, 1 lport/LS, 1 LR" test case creates a
> configuration including a logical router, then:
> 1) Sends a packet that is expected to be forwarded by the
> logical router.
> 2) Disables the logical router.
> 3) Sends another packet, identical to the one sent in (1), that
> should not be forwarded.
>
> This test case fails intermittently, apparently because the disabling
> of the logical router in (2) has not yet been propagated to the
> forwarding plane at the time the second packet is sent. (When the
> failure occurs, two packets are captured whereas only one is expected.)
>
> Address this issue by adding a one second sleep between steps (2) and
> (3). Adding a sleep does not actually fix anything, but it
> does make this test case more likely to work correctly.
>
> In one series of tests, this test case failed 11 times out of 20
> without this fix and succeeded 20 times out of 20 attempts with
> this fix.
