pytest中的pytest_addoption钩子函数-添加额外命令行,并且在用例中获取命令行传参

详细学习地址：https://blog.csdn.net/fx20211108/article/details/124719004

在conftest.py文件中：

import pytest


# 注册自定义参数 cmdopt 到配置对象
def pytest_addoption(parser):
    parser.addoption("--cmdopt", action="store",
                     default="None",
                     help="将自定义命令行参数 ’--cmdopt' 添加到 pytest 配置中")

测试用例test_1.py中获取命令行参数

def test_1(pytestconfig):
    cmd_val = pytestconfig.option.cmdopt  # 获取命令行参数
    assert cmd_val == 1

执行用例：

pytest test_1.py --cmdopt='123123'

输出结果：
