Consider the following example:
import unittest
def foo():
for x in [1, 2, 'oops', 4]:
print(x + 100)
class TestFoo(unittest.TestCase):
def test_foo(self):
self.assertIs(foo(), None)
if __name__ == '__main__':
unittest.main()
If we were calling `foo` directly we could enter post-mortem debugging via
`python -m pdb test.py`.
However since `foo` is wrapped in a test case, `unittest` eats the exception
and thus prevents post-mortem debugging. `--failfast` doesn't help, the
exception is still swallowed.
Since I am not aware of a solution that enables post-mortem debugging in such a
case (without modifying the test scripts, please correct me if one exists), I
propose adding a command-line option to `unittest` for [running test cases in
debug
mode](https://docs.python.org/3/library/unittest.html#unittest.TestCase.debug)
so that post-mortem debugging can be used.
P.S.: There is also [this SO
question](https://stackoverflow.com/q/4398967/3767239) on a similar topic.
