It's not a matter of an optional doctest flag. The Sage code says (in
cell_complex.py)
if isinstance(self, CubicalComplex):
if have_chomp('homcubes'):
H = homcubes(self, subcomplex, **kwds)
elif isinstance(self, SimplicialComplex):
if have_chomp('homsimpl'):
H = homsimpl(self, subcomplex, **kwds)
So if you are computing the homology of a simplicial complex and Sage can
find the CHomP executable homsimpl, it runs it to compute the homology. See
#16364 for doctest errors related to CHomP.
