In the current version of the new test system, there is support for 'requires: DATAFILESPATH' which then keys off what is configured,
similar to any other requirement on how PETSc is configured.

How would I get wPETSC_DIR?

In this case the data files is in the PETSc share directory so you should use

Hm - we use wPETSC_DIR so that the path is  valid for windows binaries aswell. 
Perhaps
the test harness will need a fix for this..

$ git grep wPETSC_DIR |grep makefile |head -3
