To run:

in python-frontend/src/main/protobuf directory, run: protoc -I=. --python_out=../../../typeshed_serializer/serializer/proto_out ./symbols.proto

pip install -r requirements.txt

tox -e selective-serialize -- custom

tox -e py314 -- tests/runners/test_tox_runner.py

tox -e py314 -- tests/runners/test_tox_runner.py::ToxRunnerTest::test_dry_run_unchanged_checksums -v

• Use python, not tox.
• Will show which calls to the tox module would have been triggered, depending on the checksums and file-system state.
• Will not perform any change.

python runners/tox_runner.py --dry_run true 

Can also be run in fail fast mode, to reflect the checksum validation used by the QA workflow

python runners/tox_runner.py --dry_run true --fail_fast true
