For those `pytest` [recommends](https://docs.pytest.org/en/7.0.x/how-to/capture-warnings.html#additional-use-cases-of-warnings-in-tests)
```python
# no_warnings
with warnings.catch_warnings():
    warnings.simplefilter(""error"")

    ...

# or, without the stacktrace
with warnings.catch_warnings(record=True) as record:
    ...

    assert len(record) == 0

# or, with `pytest.warns()`
with pytest.warns() as record:
    ...

    assert len(record) == 0

# suppress
with warnings.catch_warnings():
    warnings.simplefilter(""ignore"")

    ...
```

but those can easily get a name and be a bit easier to read. E.g. for the version of `no_warnings()` used in this PR:
```python
@contextmanager
def no_warnings():
    with warnings.catch_warnings(record=True) as record:
        yield
        assert len(record) == 0
