Hey everyone. I’m having troubles running

make test-no-spark

on kedro source code. 6 tests failing and seems like all of them related to parallel task runner. Have anyone had similar issue? My current hypothesis that it all fails due to

ModuleNotFoundError: No module named 'tests.runner'

. But wondering what might’ve caused an issue. Here is list of tests failed:

FAILED tests/framework/cli/test_cli.py::TestRunCommand::test_run_successfully_parallel - assert not 1

And here is failure of test in

test_cli.py

reporting ModuleNotFound:

hi @Vladimir Filimonov, What happen if you execute the failing tests directly?

pytest tests/framework/cli/test_cli.py

Hey @Nok Lam Chan. thanks for looking into that. when ran directly tests in

test_cli.py

pass, only complain about coverage target miss

Do you run from the root directory? I suppose it is otherwise make won’t work anyway.

sure, I ran both

make test-no-spark

and

pytest tests/framework/cli/test_cli.py

from the root directory of the git repo

Are you on M1/M2?

Intel, 2019 model

Let us know if it doesn’t work, worst case when you submit PR the CI will still do the checking, so it isn’t too bad if it’s just failing a couple of them locally.
