wget http://svn.python.org/snapshots/python3k.tar.bz2
tar xjf python3k.tar.bz2
cd python
./configure --enable-unicode=ucs4 --with-pydebug
make coverage
./python.exe Lib/test/regrtest.py -T -N test_urllib
This gives the following output:
[1/1] test_urllib
Not printing coverage data for 'Lib/test/regrtest.py': [Errno 2] No such file or directory: 'Lib/test/regrtest.py'

[123146 refs]I'm testing on Mac OS X 10.6.5.
Attached is the complete log of the shell session.
This bug might be related to bpo-10329, as the failing line was introduced in r86303. abalkin commented on Nov 27, 2010 Apparently something in the test changes the cwd.
Both of the following invocations work:
$ ./python.exe `pwd`/Lib/test/regrtest.py -T -N test_urllib
$ ./python.exe -m test.regrtest -T -N test_urllib I would suggest changing the coverage target in the Makefile. pitrou commented on Nov 27, 2010 make coverage is fine, you just have to use the "-m test.regrtest" form when running the tests.
abalkin commented on Nov 27, 2010 I would like to investigate this some more. In theory, regrtest should restore cwd before coverage results are written. doerwalter commented on Nov 29, 2010 ContributorAuthor More actions OK, I reran the test with::
./python -mtest.regrtest -T -N test_urllib
and this does indeed produce coverage files (for _abcoll, _weakrefset, abc, base64, codecs, collections, contextlib, functools, genericpath, hashlib, locale, mimetypes, os, posixpath, quopri, random, re, sre_compile, sre_parse, ssl, stat, tempfile, textwrap, trace, uu, warnings).
However running the complete test suite via::
./python -mtest.regrtest -T -N -uurlfetch,largefile,network,decimal
fails with::
Not printing coverage data for '/tmp/tmp0fdr9o/t4/sub/subsub/__init__.py': [Errno 2] No such file or directory: '/tmp/tmp0fdr9o/t4/sub/subsub/__init__.py'

$ ./python.exe -m test.regrtest -T test_trace test_pkg
... IOError: [Errno 2] No such file or directory: '/var/folders/qs/qsqFUI2xFUKG+9CTf4z7pU+++TI/-Tmp-/tmpy1iyp7/t4/sub/init.py' abalkin commented on Dec 14, 2010 I am attaching a patch that fixes write_results() and makes test_trace tests restore the tracefunc after they run. This fixes generation off the coverage files, but many tests still fail when traced. brettcannon commented on Jan 22, 2011 At least the test_trace fix for preventing the complete destruction of any preset trace should be looked at and possibly applied separately (prevents coverage.py from covering the entire test suite as well). Should probably add a test to regrtest to make sure that the trace function is not mutated after a test file runs. brettcannon commented on Jan 11, 2013 python-dev commented on Jun 29, 2014
