In doctests, I often need a temporary directory for the duration of the test.
In the test setup/teardown code, I create it and clean it up afterwards. So
the test setup/teardown methods looks something like:
import tempfile
import
... [More]
shutil
def setup(test):
test.tempdir = tempfile.mkdtemp()
# other stuff
test.globs.update({'tempdir': test.tempdir})
def teardown(test):
shutil.rmtree(test.tempdir)
variable that got injected into
the test globs (=globals):
The test setup created a temp directory for us:
>>> print tempdir
/tmp/kdf34klsdj3200880f/
This directory is placed inside the default
temporary directory on our os, which is:
>>> import tempfile
>>> tempfile.gettempdir()
'/tmp'
Well, not quite. The name of the tempdir is different all the time. And
. And on osx it is something like
and sometimes
, the doctest standard placeholder for
"something". But that can hide something:
The ... matches a lot:
>>> delete_files_but_not_too_much()
deleted ...
deleted ...
So we think we just deleted two files, but the ... also matches
complete sets of lines, so the following test could also pass:
>>> delete_files_but_not_too_much()
deleted ...
deleted ...
deleted ...
deleted ...
Oops.
from zope.testing import renormalizing
checker = renormalizing.RENormalizing([
# tempfile.gettempdir() is the OS's base tempdir
(re.compile(re.escape(tempfile.gettempdir())),
'TMPDIR')])
# Don't forget to pass the checker to the testrunner.
This grabs the default base temporary directory where tempfile creates its
items. So creates a temporary directory inside the
folder. Your doctests can be more explicit this
way:
>>> delete_files_but_not_too_much()
deleted TMPDIR/...
deleted TMPDIR/...
You can do one better by also normalizing the actual created temporary
directory. The trick here is to call
...
def setup(test):
test.tempdir = tempfile.mkdtemp(prefix='mytest')
...
. We cannot
directly use the created tempdir's name in a normalizer regex as the tempdir
is normally created in the setup method and the normalizer method is outside
it. The prefix helps us however in doing it anyway:
checker = renormalizing.RENormalizing([
# Normalize tempdirs. For this to work reliably, we need
# to use a prefix in all tempfile.mkdtemp() calls. We
# look for the base tempdir, followed by the prefix,
# followed by several non-slash characters.
(re.compile(
'%s/mytest[^/] ' % re.escape(tempfile.gettempdir())),
'MYTEST'),
# We probably also still need TMPDIR. Place it after
# the more specific checks otherwise it matches first...
(re.compile(re.escape(tempfile.gettempdir())),
'TMPDIR')])
Tadah, the doctest can now be really specific with no chance of erroneous
hiding of lines:
MYTEST is the tempdir the setup prepared for us
>>> delete_files_but_not_too_much()
deleted MYTEST/file1.txt
deleted MYTEST/file4.txt
base
tempdir. Mostly when you call the python executable from within your
doctest. So I had to add an extra normalizer to also detect that variant... [Less]

A couple of years ago I got a script from Guido Wesdorp for cleaning up EOL
styles in svn. I've long kept a private (modified) copy of that file and only
later found out that it was from the pypy project:
: The script goes through a
... [More]
directory structure and fixes
non-native EOL endings in non-binary files. So the windows line endings are
gone if you work on linux (and probably vice versa, though I didn't try).
When you use svn and you work with programmers both on windows and unix, you
can get EOL differences. Windows uses .
There's a simple fix to prevent any problems: use subversion's native EOL
style support, see for instance
on how to do it and why it is a good idea.
If you don't have it set (mostly programmers working on linux) and you add a
file, it doesn't get the svn setting automatically. Once
a windows programmer makes a checkout and saves it with his windows
lineendings and you re-open it on unix, you get unneeded extras at the end of
your line.
