## Name: test_preserve_and_reused_fip
## Desc: The steps in this test case:
## 1. Create load balanccer with loadbalancer.openstack.org/keep-floatingip: "true" annotation
## 2. Delete the load balancer
## 3. Check if the floating IP is preserved after deletion
## 4. Create new load balancer reassigning the floating IP allocated in point 1.
## 5. Delete the service and the allocated floating ip.

openstack floating ip show and checking return code?

Same here, plus I'd rather rely on ID here to double-check if IP wasn't deleted and recreated.

You could do show with an exact expected name. That could be useful if we'll add new tests with healthmonitors later.

HM=`openstack loadbalancer healthmonitor show "$HM_ID" -f json`

HM_DELAY=`echo "$HM" | jq '.delay'`
HM_MAX_RETRIES=`echo "$HM" | jq '.max_retries'`
HM_TIMEOUT=`echo "$HM" | jq '.timeout'`
HM_MAX_RETRIES_DOWN=`echo "$HM" | jq '.max_retries_down'`

if [ "$HM_DELAY" -ne "61" ]; then
printf "The healthmonitor DELAY doesn't match the one in the service specification"
exit 1

if [ "$HM_MAX_RETRIES" -ne "7" ]; then

exit 1

if [ "$HM_TIMEOUT" -ne "32" ]; then
