Testing

Pytest is the primary path for focused unit and regression coverage.

For regression coverage around socket/protobuf/login behavior, run:

uv run pytest tests/unit/test_socket_regressions.py

You can also run the broader pytest suite with:

uv run pytest tests/

For broader integration coverage against a real Mezon environment, set the required MEZON_* environment variables and run:

uv run python -m tests.test_runner

The integration runner includes the reconnect/login suite in tests/test_reconnect.py.
