如何將 arguments 傳遞給 pytest 夾具？

Question

I'd like to create a session with specific user email and password, for that I need to pass these two pieces of information to a pytest fixture as arguments.

我這樣做的嘗試：

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

The problem is that _update_credentials returns a function object instead of JSON, which raises TypeError: Object of type function is not JSON serializable

我該怎么做才能正確地為這個夾具提供 email 和密碼？ 請幫幫我：）

您似乎想要做的是將工廠用作固定模式，如下所示：

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

但似乎你可以這樣做：

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
