pytest fixture执行顺序

module和function的调用顺序：

import pytest

@pytest.fixture(scope="module", params=["mod1", "mod2"])
def modarg(request):
    param = request.param
    print ("  SETUP modarg %s" % param)
    yield param
    print ("  TEARDOWN modarg %s" % param)

@pytest.fixture(scope="function", params=[1,2])
def otherarg(request):
    param = request.param
    print ("  SETUP otherarg %s" % param)
    yield param
    print ("  TEARDOWN otherarg %s" % param)

def test_0(otherarg):
    print ("  RUN test0 with otherarg %s" % otherarg)


def test_1(modarg):
    print ("  RUN test1 with modarg %s" % modarg)


def test_2(otherarg, modarg):
    print ("  RUN test2 with otherarg %s and modarg %s" % (otherarg, modarg))

结果：
