___________________________________ ERROR collecting test session ____________________________________
Defining 'pytest_plugins' in a non-top-level conftest is no longer supported:
It affects the entire test suite instead of just below the conftest as expected.
/home/vagrant/src/radiasoft/pykern/tests/pkcli/projex_work/proj1/tests/conftest.py
Please move it to a top level conftest file at the rootdir:
/home/vagrant/src/radiasoft/pykern

There's a lot of cruft.
