如何将参数传递给最远的夹具？

Question

我想创建一个具有特定用户电子邮件和密码的会话，因为我需要将这两条信息作为参数传递给pytest治具。

我试图这样做：

from pytest import fixture
from api_methods import ApiMethods


@fixture(scope="session")
def user_session():

    def _update_credentials(email, password):
        user_credentials = {
            "email": email,
            "password": password
        }
        return user_credentials

    session = ApiMethods()
    session.get_authorized(_update_credentials)
    return session

问题是_update_credentials返回一个函数对象而不是JSON，这会引发TypeError:函数类型的对象不能被JSON序列化

怎样才能正确地提供电子邮件和密码？请帮帮我:)

您所要做的似乎是像这样使用工厂化夹具图案：

from pytest import fixture
from api_methods import ApiMethods


@fixture(scope="session")
def update_credentials():
    def _update_credentials(email, password):
        user_credentials = {
            "email": email,
            "password": password
        }
        return user_credentials

    return _update_credentials


@fixture(scope="session")
def user_session(update_credentials):
    user_credentials = update_credentials("email1", "password1")
    session = ApiMethods()
    session.get_authorized(user_credentials)

    return session

但似乎你可以这样做：

from pytest import fixture
from api_methods import ApiMethods


@fixture(scope="session")
def user_session():
    user_credentials = {
        "email": email,
        "password": password
    }
    session = ApiMethods()
    session.get_authorized(user_credentials)

    return session
