Numerours PytestDeprecationWarning raised when using Sybil

[Scott Dixon]

myvenv/python3.9/site-packages/sybil/integration/pytest.py:58: 193 warnings
  myvenv/lib/python3.9/site-packages/sybil/integration/pytest.py:58: PytestDeprecationWarning: A private pytest class or function was used.
    self._request = fixtures.FixtureRequest(self)

-- Docs: https://docs.pytest.org/en/stable/warnings.html

This has been going on for awhile. Doesn't break anything but it does normalize deviance having a huge number of warnings we are supposed to ignore.

Any ideas how we could fix this?

[Chris Withers]

Do you have the full traceback for one of these?

[J S Borbely]

As of pytest 6.2.0 the FixtureRequest class (and many other classes within _pytest) should be accessed this way.

However, the docs state

Constructing them is not supported (except for MonkeyPatch); they are only meant for use in type annotations. Doing so will emit a deprecation warning, and may become a hard-error in pytest 7.0.

Subclassing them is also not supported. This is not currently enforced at runtime, but is detected by type-checkers such as mypy.

@thirtytwobits You can silence this warning from being displayed by adding the following to your ini file

[pytest]
filterwarnings =
    ignore:A private pytest class or function was used:DeprecationWarning

[Chris Withers]

Yeah, let's see what the latest hoop is that Sybil needs to jump through: pytest-dev/pytest#8832

Awesome! Tested this change against my code and it works great. Thanks.
