funcarg/fixture uses a different reference to object

Something like this (using old funcargs) used to work on 2.2
but now fails on 2.3.

#!python
import pytest

class TestClass:
    @pytest.fixture()
    def my_setup(self, request):
        self.foo = True

    def test_method1(self, my_setup):
       assert self.foo

The object instance used to run the test is different from
the instance used to calculate the value of the fixture.
So modification to "self" in the fixture are lost.

seems to be a regression, indeed. Not sure why there wasn't a test for this already.

Meanwhile you can use "request.instance.foo = True".

fix issue203 - fixture functions with a scope=function should have a "self" that points to the actual instance with which the test functions run.

you can install the new version with "pip install -i http://pypi.testrun.org -U pytest" which should give you at least "dev2". Would be good if you confirm it works for you. Willthen do another release on monday or so. Let the bug reports flow :)

works for me. thanks for the quickly reply.

sorry for testing after the release... I planned to try py.test2.3 on the weekend but you were faster than me :D I converted some tests to 2.3 style and i like the result. cheers

thanks for confirmation and feedback! I did a pytest-2.3.1 release - i'd like others to spare the experience/bug :)
