Session-scoped fixture executed too many times with -x / --maxfails #1024
Description
This is related, but I think slightly different than #868 and #420 (which deals with the fact that these flags do not stop execution after a fail).
Observe this test file:
import sys
from time import sleep
from pytest import fixture
# hack for live prints (https://stackoverflow.com/questions/27006884)
sys.stdout = sys.stderr
@fixture(scope='session', autouse=True)
def session_fixture():
print('### executing fixture! ###')
def test_1():
assert False
def test_2():
sleep(1)
def test_3():
sleep(1)
def test_4():
sleep(1)Running this with:
pytest test_parallel.py -n 2 -s --maxfail=1
leads to the session_fixture being executed 3 times! Removing --maxfail=1, you can see session_fixture is executed twice (as expected).
