Ok, let's take a > look at new one our engineers found today in 4.10:
So, the point is, how do we (users, devs, all) improve quality? Marvin is great for smoke testing but CloudStack is dealing with many infra vendor components, which are not covered by the tests. How can we detect flows not covered by marvin? For me, I decided (independent of this discussion) to write integration tests in a way one would not expect, not following the "happy path": Try to break CloudStack, to make a better CloudStack. Put a chaos monkey in your test infra: Shut down storage, kill a host, put latency on storage, disable network on hosts, make load on a host. read only fs on a cluster wide primary fs. shut down a VR, remove a VR. Things that can happen! Not surprisingly I use Ansible. It has an extensive amount of modules which can be used to battle prove anything of your infra. Ansible playbooks are fairly easy to write, even when you are not used to write code. I will share my works when ready. René
