No, there is no such variable. ptests is meant to be executed from the 
toplevel directory of Frama-C or of a plugin, with a subdirectory named 
tests containing other subdirectories. Thus, EXECNOW should be LOG 
res.txt echo toto > tests/test1/result/res.txt

To be frank, ptests has never been thought as a general-purpose testing 
framework. It is only there to perform the non-regression tests of 
Frama-C (and some of its plug-ins). Thus, it must be launched in an 
environment similar to Frama-C sources.
By the way, if you want to launch ptests only on one suite or even on 
one test case, this is perfectly possible from the toplevel directory:
ptests.byte test1
ptests.byte tests/test1/hello.c

Yes, FILTER will be applied to the main command stdout and stderr. The 
command should read from stdin and output its result on stdout.

Hope this helps,
