Open Stack

Thanks Eli for the analysis.  I notice that the time to download the image
is only around 1:15 mins out of some 21 mins to set up devstack.  So it
seems trying to reduce the size of the image won't make a significant
improvement in the devstack time.   I wonder how the image size affects the
VM creation time for the cluster.  If we can look at the Heat event stream,
we might get an idea.
Ton,

Eli,

First of all I would like to say thank you for your effort (I never seen so
many path sets ;)), but I don’t think we should remove “tls_disabled=True”
tests from gates now (maybe in L).
It’s still vey commonly used feature and backup plan if TLS doesn’t work
for some reasons.

I think it’s good idea to group tests per pipeline we should definitely
follow it.

?

Subject: [openstack-dev] [Magnum][Testing] Reduce Functional testing on
gate.

hello all:

I will update some Magnum functional testing status, functional/integration
testing
is important to us, since we change/modify the Heat template rapidly, we
need to
verify the modification is correct, so we need to cover all templates
Magnum has.
and currently we only has k8s testing(only test with atomic image), we need
to
add more, like swarm(WIP), mesos(under plan), also , we may need to support
COS image.
lots of work need to be done.

for the functional testing time costing, we discussed during the Tokyo
summit,
Adrian expected that we can reduce the timing cost to 20min.

I did some analyses on the functional/integrated testing on gate pipeline.
the stages will be follows:
take k8s functional testing for example, we did follow testing case:

1) baymodel creation
2) bay(tls_disabled=True) creation/deletion
3) bay(tls_disabled=False) creation to testing k8s api and delete it after
testing.

for each stage, the time costing is follows:

  *   devstack prepare: 5-6 mins
  *   Running devstack: 15 mins(include downloading atomic image)
  *   1) and 2) 15 mins
  *   3) 15 +3 mins

totally about 60 mins currently a example is 1h 05m 57s
see
http://logs.openstack.org/10/243910/1/check/gate-functional-dsvm-magnum-k8s/5e61039/console.html

for all time stamps.

I don't think it is possible to reduce time to 20 mins, since devstack
setup will take 20 mins already.

To reduce time, I suggest to only create 1 bay each pipeline and do vary
kinds of testing
on this bay, if want to test some specify bay (for example, network_driver
etc), create
a new pipeline .

So, Ｉ think we can delete 2), since 3) will do similar things
(create/delete), the different is
3) use tls_disabled=False. what do you think ?
see https://review.openstack.org/244378 for the time costing, will reduce
to 45 min (48m 50s in the example.)

=================================
For other related functional testing works:
I 'v done the split of functional testing per COE, we have pipeline as:

  *   gate-functional-dsvm-magnum-api 30 mins
  *   gate-functional-dsvm-magnum-k8s 60 mins

And for swam pipeline, patches is done, under reviewing now(works fine on
gate)
