Nosetests ran 0 tests

When I run

nosetests --doctest-extension=.txt

I get

Ran 0 te开发者_开发问答sts in 0.002s

OK

Why does it say 0 tests when I have tests in the file README.txt?

If you're using doctest you also have to specify that nose has to run with the doctest plugin enabled.

This should do the trick:

nosetests --with-doctest --doctest-extension=txt
