Pytest如何使用多个场景参数化测试？

Question

我正在使用pytest、boto3和aws，并希望使用参数化测试进行动态断言。如何改进此代码，使其仅在特定的子网组上断言

production_private_ids = ["subnet-08f6d70b65b5cxx38", "subnet-0b6aaaf1ce207xx03", "subnet-0e54fda8f811fxxd8"]) ....
nonproduction_private_ids = ["subnet-11f6xx0b65b5cxx38", "subnet-116aaaf1ce207xx99", "subnet-11xxfda8f811fxx77"]) ....


@pytest.mark.parametrize("subnet", ["production_private_ids", "nonproduction_private_ids", "nonproduction_public_ids","production_public_ids ")

# if environment = production, then only check if production_private_ids exists in team_subnet

def test_sharing_subnets_exist(subnet,accountid):
    team_subnet =  get_team_subnets(accountid)
    assert subnet in team_subnet


# if environment = nonproduction, then only check if nonproduction_private_ids exists in team_subnet
def test_sharing_subnets_exist(subnet,accountid):
    team_subnet =  get_team_subnets(accountid)
    assert subnet in team_subnet

如果需要在参数化上执行其他逻辑，可以通过metafunc参数化测试。例如：

import os
import pytest

production_private_ids = [...]
nonproduction_private_ids = [...]


def pytest_generate_tests(metafunc):
    # if the test has `subnet` in args, parametrize it now
    if 'subnet' in metafunc.fixturenames:
        # replace with your environment check
        if os.environ.get('NAME', None) == 'production':
            ids = production_private_ids
        else:
            ids = nonproduction_private_ids
        metafunc.parametrize('subnet', ids)


def test_sharing_subnets_exist(subnet, accountid):
    team_subnet =  get_team_subnets(accountid)
    assert subnet in team_subnet

现在运行pytest ...将只检查非生产ID，而NAME="production" pytest ...将只检查生产ID
