如何将 redux saga yield 导入我的 detox + jest 测试文件。我需要在我的测试设置中访问存储在 redux 存储中的数据

这是一个 react-native 应用程序，我目前正在编写一些端到端的测试。

令牌存储在如下所示的 redux 存储中，我正在使用 detox/jest 测试登录功能。我需要检测令牌是否存在于我的 login.spec.js 的商店中。如果令牌存在，我想从商店中擦除它，这样当我重新加载应用程序以将用户带回另一个场景时，用户不会自动登录。有问题的主要功能是 refreshUserToken() 和行：-

const { refresh_token } = yield select(token);

这是位于以下位置的 redux saga 文件 User.js：-MyApp/App/Sagas/User.js

import { call, put, takeEvery, select } from "redux-saga/effects";
import Config from "MyApp/App/Config";
import API from "MyApp/App/Services/API";
import { when } from "MyApp/App/Helpers/Predicate";
import Credentials from "MyApp/App/Helpers/Credentials";
import ActionCreator from "MyApp/App/Actions";

const appendPayload = payload => {
  return {
    ...payload,
    // Removed because no longer needed unless for testing purposes.
    // username: Config.TEST_USERNAME,
    // password: Config.TEST_PASSWORD,
    client_id: Config.CLIENT_ID,
    client_secret: Config.CLIENT_SECRET,
  };
};

const token = state => state.token;

const user = state => state.user;


const attemptUserLogin = function*(action) {
  const { payload } = action;
  const login = "/oauth/token";
  const grant_type = "password";
  const loginPayload = appendPayload(payload);

  action.payload = {
    ...loginPayload,
    grant_type,
  };

  yield attemptUserAuthorisation(login, action);
};

const attemptUserRegister = function*(action) {
  const register = "/api/signup";
  const { payload } = action;
  yield Credentials.save(payload);
  yield put(ActionCreator.saveUserCredentials(payload));
  yield attemptUserAuthorisation(register, action);
};

const refreshUserToken = function*(action) {
  const login = "/oauth/token";
  const grant_type = "refresh_token";
  const { refresh_token } = yield select(token);

  action.payload = {
    ...action.payload,
    grant_type,
    refresh_token,
  };
  yield attemptUserAuthorisation(login, action);
};

const watchExampleSaga = function*() {
  yield takeEvery(ActionCreator.AUTO_USER_LOGIN, autoUserLogin);
  yield takeEvery(ActionCreator.USER_LOGIN, attemptUserLogin);
  yield takeEvery(ActionCreator.USER_REGISTER, attemptUserRegister);
  yield takeEvery(ActionCreator.USER_REFRESH_TOKEN, refreshUserToken);
};

export default watchExampleSaga;

这是我的 detox/jest 规范文件，位于：-MyApp/App/e2e/login.spec.js

    describe('Login Actions', () => {

  it('Should be able to enter an email address', async () => {
    await element(by.id('landing-login-btn')).tap()
    const email = '[email protected]'

    await element(by.id('login-email')).tap()
    await element(by.id('login-email')).replaceText(email)
  });

  it('Should be able to enter a password', async () => {
    const password = 'secret'

    await element(by.id('login-password')).tap()
    await element(by.id('login-password')).replaceText(password)
  });

  it('Should be able to click the continue button and login', async () => {
    await element(by.id('login-continue-btn')).tap()
    await waitFor(element(by.id('dashboard-logo'))).toBeVisible().withTimeout(500)

    // If token exists destroy it and relaunch app. This is where I need to grab the token from the redux saga!
    await device.launchApp({newInstance: true});
  });
})
