How to make py.test run doctests as well as normal tests directory?

问题

We currently have py.test 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.

回答1:

Now it is implemented :-).

To use, either run py.test --doctest-modules command, or set your configuration with pytest.ini:

$ cat pytest.ini
# content of pytest.ini
[pytest]
addopts = --doctest-modules

Man page: PyTest: doctest integration for modules and test files.

回答2:

Could you try with the repo version of pytest and paste a session log? I'd think --doctest-modules should pick up any .py files.

回答3:

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.
