Disable jaxtyping for individual tests

Hi, I'm using jaxtyping in my test suite have a particular test that is slowed down extremely by jaxtyping and typeguard. I'm talking ~7 minutes with

[tool.pytest.ini_options]
addopts = "--jaxtyping-packages=mypackage,typeguard.typechecked"

and only ~4s without. I tried disabling type checking for this test using

@typing.no_type_check
def test_my_function() -> None:
    ...

but sadly, that doesn't seem to speed things up.

Are there any workarounds for this?

P.S.:

The above example is a simplified version of the following decorator which I am already using successfully on "normal" functions outside of the test files.

W = TypeVar("W")
def no_runtime_typecheck(fun: W) -> W:
    """Applies the ``no_type_check`` decorator during runtime (for typeguard/beartype/
    jaxtyping/...) but not during static analysis (e.g. mypy)."""
    if typing.TYPE_CHECKING:
        return fun
    return typing.no_type_check(fun)  # type: ignore[unreachable]

Start by tracing how the pytest option --jaxtyping-packages=mypackage,typeguard.typechecked applies runtime checking to individual tests, and compare that behavior with typing.no_type_check and the shown no_runtime_typecheck decorator. Done means a single test can opt out of jaxtyping and typeguard overhead without disabling checking for the rest of the suite; the issue does not name a file or test to run.
