Is it possible to write a doctest unit test that will check that an exception is raised?
For example, if I have a function foo(x) that is supposed to raise an exception if x < 0, how would I write the doctest for that?
Can you check that an exception is thrown with doctest in Python?

Yes. You can do it. The doctest module documentation and Wikipedia has an example of it.
>>> x
Traceback (most recent call last):
...
NameError: name 'x' is not defined
>>> scope # doctest: +IGNORE_EXCEPTION_DETAIL
Traceback (most recent call last):
NameError: name 'scope' is not defined
Don't know why the previous answers don't have the IGNORE_EXCEPTION_DETAIL. I need this for it to work. Py versioin: 3.7.3.
