[OpenAFS] buildbot and packages
Mon, 17 Sep 2012 23:08:04 -0500
Nope, Debian x86-64
Any chance the buildbots can be easily modified to run make check/make tests?
I'm really curious what debian ppc32/ppc64 will do. I have an arm build, but
no fuse kernel module (debian on an sdcard on an android tablet).

You need to have a lot of surrounding infrastructure that involves real control of a fair amount of stuff that random college students won't have. 'make check' on a single machine will never give you useful testing results other than to find packaging or "smoke test" errors, which aren't all that helpful overall.

A uncoordinated test process is unlikely to produce anything useful in that there have to be a sequence of coordinated tests, replacing one component at a time in a known order. I can't see how crowdsourcing would help here.
