yes... that's the "claim" ...
if we say its been burnt in for 72 hrs...
- they get a list of times and dates ...
- i prefer to do infinite kernel compiles
( rm -rf /tmp/linux-2.x ; cp -par linux-2.x /tmp ; make bzImage ;
( a dumb/simple/easy test that runs few standard operations )

yes... that is the trick .... to get a god set of test suites

keeping testing costs time down and "start testing process all over is
testing and diags
and everybody has their own idea of what tests to do .. and "its
considered tested" ... or the depth of the tests..
1st tests should be visual ..
- check the bios time stamps and version
- check the batch levels of the pcb
- check the manufacturer of the pcb and the chips on sdrams
- blah ... dozens of things to inspect
than the power up tests
- run diags to read bios version numbers
- run diags for various purposes
- diagnostics and testing should be 100% automated including
generating failure and warning notices
- people tend to get lazy or go on vacation
and most are not as meticulous about testing foo-stuff
while the other guyz might care that bar-stuff works
- testing is very very expensive ...
- getting known good mb, cpu, mem, disk, fans
( repeatedly ) is the key ...
- problem is some vendors discontinue their mb in 2 months
so the whole testing clock start over again
- in our case, its cheaper to find smaller distributors
that have inventory of the previously tested known good mb
that we like
- if it aint broke... leave it alone .. if its doing its job :-)
