PyTest中是否有直接将命令行参数传递给conftest.py的方法?

我知道有一种方法可以在测试本身中通过args，就像这里显示的那样，但是有没有一种方法可以直接在conftest.py中通过呢?我想以这种方式为所有测试配置一些通用的东西。 这是我的自白。

 import pytest
 from appium import webdriver
 import json
 import os

 from config import *

 CAPS_FILE = "android_9.0_emulator.json"


 def pytest_addoption(parser):
     parser.addoption("--desired-capabilities", action="store", default=CAPS_FILE)


 def pytest_generate_tests(metafunc):
     # This is called for every test. Only get/set command line arguments
     # if the argument is specified in the list of test "fixturenames".
     option_value = metafunc.config.option.name
     if 'desired-capabilities' in metafunc.fixturenames and option_value is not None:
         # metafunc.parametrize("desired_capabilities", [option_value])
         CAPS_FILE = option_value


 def get_desired_caps(json_file):
     with open(desired_caps_dir_path) as json_file:
         return json.load(json_file)


 @pytest.fixture(scope="session")
 def browser():
     driver = webdriver.Remote(appium_driver_url, desired_capabilities=get_desired_caps(CAPS_FILE))
     # driver = webdriver.Remote(appium_driver_url, desired_capabilities=get_desired_caps(metafunc.config.option))
     yield driver
     driver.quit()

更新:或者我应该使用这个函数来初始化/配置contest .py本身从命令行:

def pytest_configure(config):
     option_val = config.option.name
     if 'desired-capabilities' in config.option and option_val is not None:
         CAPS_FILE = option_val

或者可能有更好的方法? 问题来源StackOverflow 地址：/questions/59386296/is-there-a-way-in-pytest-to-pass-command-line-arguments-to-conftest-py-directly
