I wrote a small pytest plugin that is inspired by pytest-doctestplus, whose purpose is to enable doctest discovery for Numpy ufuncs:
https://github.com/lpsinger/pytest-doctest-ufunc

It is used by another project of mine:
https://git.ligo.org/lscsoft/ligo.skymap

The code is very similar to pytest-doctestplus because it is adapted from it. Would it be appropriate to contribute its functionality to pytest-doctestplus?
