运行测试时未找到夹具（DDT Pytest）

我遇到了一个错误；夹具“无效电子邮件”；运行此测试时未找到：

import pytest
import time
from ddt import ddt, data, unpack
from pages.home.signup_page import SignUpPage
from utilities.read_data import get_csv_data
@pytest.mark.usefixtures("base_set_up", "set_up")
@ddt
class TestSignUp():
    @pytest.fixture(autouse=True)
    def class_set_up(self, base_set_up):
        self.test_user = SignUpPage(self.driver)
    @pytest.mark.run(order=2)
    def test_valid_sign_up_with_confirmation(self):
        self.test_user.valid_signup()
        self.test_user.use_mailer()
        result = self.test_user.verify_successful_sign_up()
    @pytest.mark.run(order=1)
    @data(*get_csv_data('/Users/blabla/utilities/test_data.csv'))
    @unpack
    def test_invalid_sign_up_invalid_email(self, invalid_email):
        self.test_user.invalid_signup(invalid_email)
        time.sleep(3)
        result = self.test_user.verify_error_sign_up()

会发生什么？我已经仔细检查了文件testu数据。csv用于额外空间等。文章源自玩技e族-https://www.playezu.com/180095.html

fixture 'invalid_email' not found
available fixtures: base_set_up, browser...
use 'pytest --fixtures [testpath]' for help on them.
