py.test session level fixtures in setup_method

Question

Is there a way to somehow use pytest fixtures from conftest.py in a test class\'s setup? I need to initialize an object when the session starts and use it in so

Answer 1

I used this kind of a setup for a test class with pytest<=3.7.0 (it stopped working with pytest 3.7.1 release):

# conftest.py:

import pytest

# autouse=True does not work for fixtures that return value
# request param for fixture function is only required if the fixture uses it:
# e.g. for a teardown or parametrization. Otherwise don't use it.
@pytest.fixture(scope="session")
def myfixture():
    return "myfixture"

# test_aaa.py

import pytest

class TestAAA(object):
    @classmethod
    @pytest.fixture(scope="class", autouse=True)
    def setup(self, myfixture):
        self.myfixture = myfixture

    def test_function1(self):
        # now you can use myfixture without passing it as param to each test function   
        assert self.myfixture == "myfixture"
