❯ ./pants help python_test

`python_test` target
--------------------

A single Python test file, written in either Pytest style or unittest style.

All test util code, including `conftest.py`, should go into a dedicated `python_source` target and then be included in the
`dependencies` field. (You can use the `python_test_utils` target to generate these `python_source` targets.)

See https://www.pantsbuild.org/v2.8/docs/python-test-goal

Valid fields:

timeout
    type: int | None
    default: None
    A timeout (in seconds) used by each test file belonging to this target.

    This only applies if the option `--pytest-timeouts` is set to True.
