Is there some way to postpone execution of fixtures until into the spawned

One solution would be to do a small refactoring in your fixtures, to also
expose their functionality as functions. For example:

@pytest.fixturedef resource(tmp_path):
    result = Resource(tmp_path)
    yield result
    result.close()

Into:

@contextmanagerdef using_resource(path):
    result = Resource(path)
    try:
        yield result
    finally:
        result.close()
@pytest.fixturedef resource(tmp_path):
    with using_resource(tmp_path) as result:
        yield result

Cheers,
Bruno.
