The tested use case is an autoscaling group of web app servers behind a loadbalancer. Test template was rewritten to use AutoScalingGroup, wait conditions and outputs, so no other client than heat one is used. Now there is no need to check for VM connectivity, as stack/resources status COMPLETE now quite reliably means that the listening servers are running. This patch should probably also help with narrowing down the causes of bug 1437203, since it does not checks instance connectivity with SSH.

Template which tests Neutron load balancing requests to members of
|
|
Heat AutoScalingGroup.
|
|
Instances must be running some webserver on a given app_port
|
|
producing HTTP response that is different between servers
|
|
but stable over time for given server.
