- Add @cpython_only decorator to lazy import tests
- Rename reference to SOURCE format
- Always two newlines between test case classes
- Merge two classes of ForwardRef tests
- Use get_annotations instead of annotationlib.get_annotations
- Format test_annotationlib with Black (not expecting that we'll keep this up
but it's close to Black-formatted right now)
This ensures that if we jump through some hoops to make sure something is imported
lazily, we don't regress on importing it.
I recently already accidentally made typing import warnings and annotationlib eagerly.

I started with just moving ForwardRefTests to test_annotationlib,
but found that it contained a number of tests for no_type_check, which
I moved to a new class in test_typing, as well as a number of tests that
are more appropriately classified as tests for get_type_hints().
One test, test_forward_equality_namespace(), was somewhat accidentally
depending on a global class A in test_typing. I added a class A in the
annotationlib tests instead.
Also add a useful comment in annotationlib.
It doesn't make sense to use a deprecation for evaluate_forward_ref,
as it is a new function in Python 3.14 and doesn't have compatibility
guarantees.
I considered making it throw an error if type_params it not passed and
there is no owner. However, I think this is too unfriendly for users. The
case where this param is really needed is fairly esoteric and I don't think
this case is worth the pain of forcing users to write "type_params=()".
Add the following methods:
* assertHasAttr() and assertNotHasAttr()
* assertIsSubclass() and assertNotIsSubclass()
* assertStartsWith() and assertNotStartsWith()
* assertEndsWith() and assertNotEndsWith()
Also improve error messages for assertIsInstance() and
assertNotIsInstance().
Fix _PyArg_UnpackKeywordsWithVararg for the case when argument for
positional-or-keyword parameter is passed by keyword.
There was only one such case in the stdlib -- the TypeVar constructor.
Unfortunately, released versions of typing_extensions
monkeypatch this function without the extra parameter, which makes
it so things break badly if current main is used with typing_extensions.
Fortunately, the monkeypatching is not needed on Python 3.13, because CPython
now implements PEP 696. By renaming the function, we prevent the monkeypatch
from breaking typing.py internals.
We keep the old name (raising a DeprecationWarning) to help other external users who call it.
