"""
Test `uv publish` by uploading a new version of astral-test-<test case> to testpypi,
authenticating by one of various options.

# Setup

**astral-test-token**
Set the `UV_TEST_PUBLISH_TOKEN` environment variables.

**astral-test-password**
Set the `UV_TEST_PUBLISH_PASSWORD` environment variable.
This project also uses token authentication since it's the only thing that PyPI
supports, but they both CLI options.
TODO(konsti): Add an index for testing that supports username/password.

**astral-test-keyring**
```console
uv pip install keyring
keyring set https://test.pypi.org/legacy/?astral-test-keyring __token__
```
The query parameter a horrible hack stolen from
https://github.com/pypa/twine/issues/565#issue-555219267
to prevent the other projects from implicitly using the same credentials.

**astral-test-trusted-publishing**
This one only works in GitHub Actions on astral-sh/uv in `ci.yml` - sorry!
