Let me hijack this thread at least a little...

First: the issue of multiple DB engines and such as real pain in the b...
for me. I'd like to have as many automated tests as possible, but all those
plugins that need "elaborate" setup usually fall short as it is pretty hard
to do (for me and on every dev machine). Remember that for some plugins I
don't even have the slightest idea of how the backend works. And for sure
not even remotely how I could conduct an automated test, which requires

a) getting to a known initial state
b) shuffeling data at a test run
c) extracting the results and check if they are ok
d) probably re-setting things to look untouched again (ok, somewhat
redundant with a).

Keeping the ES example, I know barely how I can do a, c, and d manually so
that I can conduct manual tests (and after some weeks this even requires
review of notes, as I really don't care/use ES in day-to-day operations).
Doing this in an automated way is way above my head. Now think about the
many other plugins, and those that hopefully will be written. I am not that
super-guru, and I think for many folks it's hard to be really good at all
of these tools (congrats if you are!).

Disabling a test if the feature is not enabled might help an end-"user",
but it doesn't solve the core problem that I don't detect regressions right
in time.

So... now to the hijacking. I have a dream. As a community, I think we
would be able to create a machine where we could run nightly builds,
nightly *testbench* runs (on a much more elaborate testbench including all
the backend system), night doc generation and upload ... and so on.

This would need to be a group effort as we would need to drag in all the
experts that could help craft these tests. Also, we would need some folks
who would take care of handling the server itself, I mean the usual admin
things like keeping it secure, creating user accounts for other
collaborators and so on. I know we have many site reliability engineers
(and similar positions) on our list, so they could chime in here. Such a
machine would probably also enable me to find bugs quicker. Right now, for
things like ES that I don't work on regularly, the main obstacle to start a
bughunt is to setup the env, remember how get around with it and so it. If
there is a ready machine with clear procedure, I could hunt bugs much more
efficient. But quite frankly this is a too large task for us small Adiscon
to handle. We simply have no funding for all that talent required.
Regarding the platform, I'd assume that a virtual server somewhere in the
cloud could be used (hopefully a sponsored one). And as I am right now in
"whish mode", it would help immensely to have access to maintained build
environments for Solaris, SmartOS, AIX, *BSD and so on, together with some
helping hands I could ask if I don't find may way around easily enough.

OK, that was the dream. Does anybody think we could realize at least a bit
of it in practice? ;)

Thank,
Rainer
