Pytest中我们经常会用到数据参数化，我们来介绍下装饰器@pytest.fixture()配合request传参的使用
user = request.param
如果想把登录操作放到前置操作里，也就是用到@pytest.fixture装饰器，传参就用默认的request参数
user = request.param 这一步是接收传入的参数，本案例是传一个参数情况
@pytest.mark.parametrize("input_user",user_list,indirect=True)中indirect=True是指用user_list、pwd_list数据对“input_user”、“input_pwd”这个fixture进行参数化，虽然装饰器写在测试用例上，但是却是对测试用例使用的fixture进行传递数据，这正是indirect的意思.
request传多个参数、多个fixtrue
import pytest
user_list=['wangxiao','zhangxiao']
pwd_list=['123456','123']
@pytest.fixture(scope="module")
def input_user(request):
user=request.param
print("用户名：%s"%user)
return user
@pytest.fixture(scope="module")
def input_pwd(request):
pwd = request.param
print("密码：%s"%pwd)
return pwd
@pytest.mark.parametrize("input_user",user_list,indirect=True)
@pytest.mark.parametrize("input_pwd",pwd_list,indirect=True)
def test_login(input_user,input_pwd):
print(input_user,input_pwd)
