使用 python 获取所有 pytest 节点 ID 的列表 [英] Get a list of all pytest node ids using python

问题描述

您知道是否有办法收集所有 pytest 节点 ID(如此处) 使用 pytest python API ?

Do you know if there is a way to collect all pytest node ids (as presented here) using the pytest python API ?

我找到了pytest的--collect-only参数，但是我不知道如何使用python获取输出?

I have found the --collect-only parameter of pytest, but I can't figure out how to get the output using python ?

提前致谢！

推荐答案

如果您想以编程方式访问 nodeid，最好编写一个小插件，将它们存储在测试集合中.示例:

If you want to access nodeids programmatically, best is to write a small plugin that will store them on test collection. Example:

import pytest


class NodeidsCollector:
    def pytest_collection_modifyitems(self, items):
        self.nodeids = [item.nodeid for item in items]


def main():
    collector = NodeidsCollector()
    pytest.main(['--collect-only'], plugins=[collector])
    # use collector.nodeids now

如果你想避免 pytest 输出到终端，另外禁用终端插件:

If you want to avoid pytest output to the terminal, disable the terminal plugin in addition:

pytest.main(['--collect-only', '-pno:terminal'], plugins=[collector])
