We currently have pytest with the coverage plugin running over our tests in a tests directory.
What's the simplest way to also run doctests extracted from our main code?  --doctest-modules doesn't work (probably since it just runs doctests from tests).  Note that we want to include doctests in the same process (and not simply run a separate invocation of py.test) because we want to account for doctest in code coverage.
worked with doctest as well as with plain tests in one module. for a non-doctest test to be picked up, standard py.test discovery mechanism applies: a module name with test prefix, test function with test prefix.
How to make pytest run doctests as well as normal tests directory?
