Indeed, I run it the second way (no command line on the Mac,
remember:-).
The fun thing is that if I run it completely standalone (by dragging
test_descrtut.py to the interpreter, the test can handle this
situation) it works fine! So, there must be something wrong with
either the test framework (or maybe this re-import trick?) that
doesn't work as expected on the Mac.
Maybe test_regrtest can be thought which tests use unittest or
doctest, and not try to be helpful in those cases?
For now I've just put a note in the readme file for MacPython that
this test is expected to fail, but I'd like to fix it eventually, of
course.
I have another gripe with the new unittest stuff (this is the first
time I've seen the doctest thing, never knew it was there!), and
that's that most of the test failures are difficult to
interpret. Whereas the old-style tests simply "print math.sin(math.pi)"
and tell you they expected the output to be 0 but got -1 in stead the
unittest-based tests often don't give that information.
Most of the unittest-based tests use only failUnless/assert_ in stead
of the higher-level functions, i.e. test_time uses things like
self.assert_(time.ctime(self.t)
== time.asctime(time.localtime(self.t)))
where the test results would be a lot easier to interpret if they used
self.assertEqual(time.ctime(self.t),
time.asctime(time.localtime(self.t)),
"ctime(T) != asctime(localtime(T)")
