test_posix.py of Python 3 contains the test, but the test is "disabled" (dead code):
def test_getcwd_long_pathnames(self):
 if hasattr(posix, 'getcwd'):
 dirname = 'getcwd-test-directory-0123456789abcdef-01234567890abcdef'
 curdir = os.getcwd()
 base_path = os.path.abspath(support.TESTFN) + '.getcwd'
 try:
 os.mkdir(base_path)
 os.chdir(base_path)
 except:
# Just returning nothing instead of the SkipTest exception,
# because the test results in Error in that case.
# Is that ok?
# raise unittest.SkipTest("cannot create directory for testing")
 return
 def _create_and_do_getcwd(dirname, current_path_length = 0):
 try:
 os.mkdir(dirname)
 except:
 raise unittest.SkipTest("mkdir cannot create directory sufficiently deep for getcwd test")
 os.chdir(dirname)
 try:
 os.getcwd()
 if current_path_length < 1027:
 _create_and_do_getcwd(dirname, current_path_length + len(dirname) + 1)
 finally:
 os.chdir('..')
 os.rmdir(dirname)
 _create_and_do_getcwd(dirname)
 finally:
 os.chdir(curdir)
 support.rmtree(base_path)
See the issue #17516 for removal of dead code.
