Work is heavily inspired by pytest-asyncio

Run into the issue that async tests decorated with hypothesis did not run. After digging into this a bit I found above commit in pytest-asyncio and hypothesis.

if getattr(method, "is_hypothesis_test", False) and asyncio.iscoroutinefunction(
method.hypothesis.inner_test
):
method.hypothesis.inner_test = wrap_in_sync(method.hypothesis.inner_test)

What's is the type of method when is_hypothesis_test is true? Is it something that any of the inspect.iscoroutinefunction / inspect.iscoroutine / inspect.isawaitable functions recognize?

It is just a normal function/callable. Hypothesis given decorator will "swallow" the coroutine and replace it with a normal function.

And what would be the result of method() then? A coroutine / awaitable?

If I recall correct it will be None and a python warning when debug is true.
