Could also be comparing one version of OpenSimulator against another to check for regressions or improvements.<br><br>Testing requires setting up the system under test, creating all the test bot accounts, loading a standard sim configuration, setting up data gathering, firing off one or more clients to exercise the system and then collecting and analyzing the gathered data. Each of the steps presents its own challenge to automation.<br>

<p class="MsoNormal" style="margin-bottom: 12pt;">We also need a pre defined
region with textures, objects (physical/non) and scripts running (just
like a normal scenario), a 'default' oar will work I think</p>

<p class="MsoNormal">yes, this absolutely is one way to go.<br>
<br>
we successfully experimented with<br>
- ec2 linux instances sporting the hippo viewer<br>
- streaming the hippo window output as a .flv source<br>
- emulating keystrokes to the hippo viewer to move the avatar<br>
<br>
all in all this makes a fully qualified client that hits the OpenSimulator as
hard as a real client does, still it is scriptable in a limited way. and it
would be perfectly scalable via the cloud.<br>

I haven't much dug into that, but it seems to me that a scalable cloud<br>
infra should be perfect for what you describe : large numbers of<br>
clients for a limited time, *real* different ips,...<br>
1 loader script piloting 'on the fly' created ec2/whaterver client<br>
instances, only for the time they're needed. Even for large load<br>
tests, the overall cost should noy go beyond a few dollars.<br>
<br>
> Testing the load of a large number of clients requires a lot of
infrastructure -- multiple client systems and a lot of networking. That makes
stress testing difficult to set up and to create a portable, automated stress
tester.<br>
