[gmx-developers] TestReferenceChecker and floatin problem

[David van der Spoel]

Hi,
I'm trying to finalize some test code in my energy patch but getting 
stuck on not being able to change the tolerance. The problem is I'm 
using CommandLineTestBase as a base class, which has a function 
checkOutputFiles. The files are checked but I can not seem to modulate 
the floatingpointtolerance.

E.g. when calling
 
rootChecker().setDefaultTolerance(gmx::test::relativeToleranceAsFloatingPoint(1, 
tolerance));

a fresh rootChecker is generateed for every call since in refdata.h we have

          * Each call returns an independent instance.
          */
         TestReferenceChecker rootChecker();

That means that by the time my code calls checkOutputFiles the tolerance 
settings are reset.

Clues?
