Comment #14 on issue 1641 by smichr: doctests require newline only when run
for single file
http://code.google.com/p/sympy/issues/detail?id=1641
Comment five notes a difference in behavior when running doctest with and
without and
argument. The reason for this is that when no argument is given that means
all files
will be tested. In sympy's doctest there are two levels of testing:
1) testing of *.py files with python's doctest which tests source code
files ( NOT
the doctest.testfile routine)
2) testing of doc/src/*.txt files if no argument was given OR a testing of
what was
specified with the sympy.docstring() argument. In this case, however,
doctest.testfile is used and this is better at extracting all docstrings
whether they
occur in function, class, are vectorized, or don't appear in any function
at all. The
caveat, I believe, here is that a newline is expected after code -- and
that would
usually be there in a *txt file. In a *.py file, however, it is not
uncommon to close
a docstring without a newline after the interactive code snippet and this
generates
an error.
Summary
sympy.doctest(path) =
test everything on path and if path has files AND test with
doctest.testfile
but don't do the *txt files
sympy.doctest() =
test everything on path and test ONLY doc/src/*txt files (don't test
*py files)
