解决办法

fixture函数只能传入参数request,要实现不同用户登录，可以使用如下方式

test_user_data = [{'user': 'machao341', 'pwd': '2gynz30J'}, {'user': 'chenyao007', 'pwd': '2gynz30J'}]
@pytest.fixture(autouse=True,scope='session',params=test_user_data)
def login(request):
    user = request.param['user']
    pwd = request.param['pwd']
    yield  LoginPage().login(user, pwd)

看报错, 就是fixture 的方法login_ITS(username) 没有取到 username, 把username的值写到 fixture 里面去吧. 直接传入试试.

直接写在fixture里是在conftest.py文件里传入么？如果不同用例需要不同的username,需要在用例里传入，可以实现么？

import pytest
from page.loginPage import LoginPage

# 登录ITS
# 可以传入登录的账号名称
# username = 'chenyao007'
@pytest.fixture(scope='class')
def login_ITS():
    login_ITS = LoginPage()
    username=['machao341']
    login = login_ITS.login_ITS(username)
    # 鉴权信息
    authorization = login[2]+' '+login[3]
    # 把鉴权信息放入header中共享给所有接口
    login_ITS.session.headers.update({'Authorization':authorization})

大概是这个意思.

还没有尝试过不同用户登录都写入到fixture里面, 应该也可以这么做.

感觉用例里面的话, 直接写在setup class , 里面要方便点吧. 直接取到对应的测试数据. 然后跑当前用例.
