There seems to be one intermediate step missing:

example --> doctest --> runner

>>> import doctest
>>> example = doctest.Example(
...     "print('hello world')\n",
...     want="hello world\n")
>>> test = doctest.DocTest([example], {}, None, None, None, None)
>>> runner = doctest.DocTestRunner(verbose=True)
>>> runner.run(test)
Trying:
    print('hello world')
Expecting:
    hello world
ok
TestResults(failed=0, attempted=1)

But why would you want to do that?
