pytest中fixture异常处理

一、高版本pytest使用fixture时，报异常：

AttributeError: 'str' object has no attribute 'iter_parents'：

def _test_fixtures(item):
        fixturemanager = item.session._fixturemanager
        fixturedefs = []
        if hasattr(item, "fixturenames"):
            for name in item.fixturenames:
>               fixturedef = fixturemanager.getfixturedefs(name, item.nodeid)
E               AttributeError: 'str' object has no attribute 'iter_parents'

二、解决办法

2.1 更改源代码：

fixturedef = fixturemanager.getfixturedefs(name, item.nodeid)
修改为：
fixturedef = fixturemanager.getfixturedefs(name, item)

2.2 回退版本，本质是版本不兼容导致：

回退pytest的版本由8.2.0回退到8.0.2

pip install pytest==8.0.2
