Running this test on a small system produces different failures every test checking deletions, and some flushes. From different test runs:
TEST: Common host entries configuration tests (L2) [FAIL] Failed to delete L2 host entry
TEST: Common port group entries configuration tests (IPv4 (S, G)) [FAIL] IPv4 (S, G) entry with VLAN 10 not deleted when VLAN was not specified
TEST: Common port group entries configuration tests (IPv6 (*, G)) [FAIL] IPv6 (*, G) entry with VLAN 10 not deleted when VLAN was not specified
TEST: Flush tests [FAIL] Entry not flushed by specified VLAN ID
TEST: Flush tests [FAIL] IPv6 host entry not flushed by "nopermanent" state
Add a short sleep after deletion and flush to resolve this.
Create a delay variable just for this test to allow short sleep, the lib.sh WAIT_TIME of 5 seconds makes the test far longer than necessary.
Tested on several weak systems with 0.1s delay:
- Ivy Bridge Celeron netbook (2014 x86_64)
- Raspberry Pi 3B (2016 aarch64)
- Small KVM VM on Intel 10th gen (2020 x86_64)
All these systems ran 25 test runs in a row with 100% pass OK.
