Comment #8 on issue 1641 by smichr: doctests require newline only when run
for single file
http://code.google.com/p/sympy/issues/detail?id=1641
There is a difference (apparently) between python's doctest.testfile which
will
extract and run tests from the specified file and this other approach for
assembling
the tests:
tests = doctest.DocTestFinder().find(module)
for test in tests:
runner = doctest.DocTestRunner(optionflags=doctest.ELLIPSIS | \
doctest.NORMALIZE_WHITESPACE)
old = sys.stdout
new = StringIO()
sys.stdout = new
f, t = runner.run(test, out=new.write, clear_globs=False)
The latter approach is what is being used when docstrings in *.py files are
being
tested by sympy's doctest; the former is being used when the doc/src/*
files'
docstrings are being tested.
Note in comment 4 that I got different results because I was using two
different
methods of doing the tests: first, sympys doctest which uses the 'runner'
and then
the python doctest which uses doctest.testfile.
I don't get a difference in the interpreter or command line when I run the
tests (at
least with my modified runtests.py file) EXCEPT in the case of the doc/src
tests.
From the interpreter I get error; from the command line I get NO errors

It might be useful if we came up with a little test suite for just the test
and
doctest testing files.
