I am working with some code which, for MPI-related reasons, is
constructed around a custom-built Python interpreter. I am trying to
write some tests for this code using py.test.
Trying to use the --exec option to instruct py.test to use the custom-
built Python interpreter in question, results in the following failure.
$ py.test interface/nmag --exec=~/nsim/pyfem3/pyfem3
inserting into sys.path: /home/jacek/nsim/py
Traceback (most recent call last):
File "/home/jacek/nsim/py/py/bin/py.test", line 4, in ?

File "/home/jacek/nsim/py/py/test/cmdline.py", line 13, in main
session = config.initsession()
File "/home/jacek/nsim/py/py/test/config.py", line 140, in

session = cls(self)

__init__
self._setexecutable()
File "/home/jacek/nsim/py/py/test/terminal/remote.py", line 70, in
_setexecutable
assert executable is not None, executable
AssertionError
Looking at the source code, it is far from clear to me what the
problem might be. What sort of values of --exec should I expect to
work/fail?
Thanks.
P.S. I'm puzzled by the purpose of ", executable" in line 70 of
remote.py: when the assertion fails, executable will always be None,
so no message will ever appear.
