"""Main configuration file for pytest.

Contents:
adds an --only_changed_modules option to pytest
this allows to turn on/off differential testing (for shorter runtime)
"on" condition ensures that only estimators are tested that have changed,
    more precisely, only estimators whose class is in a module
    that has changed compared to the main branch
by default, this is off, including for default local runs of pytest
