[Insight-developers] Testing and stderr

[Bill Hoffman]

Hi,

I was thinking that the current dashboard software should be changed from
looking for any stderr output to looking for patterns and return values from
executables.

The vnl tests are already printing out PASSED or FAILED for individual tests.
It would be nice if the dashboard software did a grep in the output of each
program, and counted the number of PASSED and FAILED, and printed a summery. 
To be a general purpose testing framework, check for cerr output is a bit
limiting, and is often used for non error conditions.   Counting passed and
failed gives more information and gets around flagging stderr output as an
error.
