[aspect-devel] Aspect 2.0 tests failure question

[Wolfgang Bangerth]

Ravi,

> I ran Aspect (2.0 pre) tests with "make setup_tests", and "make test" from the

> the (attached) summary screen output from the tests, I see that 194/558 (or 
> nearly 35%) tests failed.

That is a pretty normal number. It is because every compiler and processor 
produces results that differ very slightly. ASPECT stores "correct" output in 
the tests/<TESTNAME>/ directories (corresponding to the tests/<TESTNAME>.prm 
file) and after running the ASPECT executable on the .prm file, simply does a 
diff between your output and the stored one.

If you want to see the differences, do something like
   ctest -V -R <TESTNAME>
and it will give you an idea how these differences look like -- generally, 
they should be in the 6th or 7th digit of all outputs.

Best
  W.
