* add forwards slashes to path redirects

* fix cypress path tests again

* plese cypress

* fix: test different challenge

Okay so I literally have no idea why this one particular challenge
fails in Cypress Firefox ONLY. Tom and I paired and spun a full build
instance and confirmed in Firefox the page loads and redirects as
expected. Changing to another bootstrap challenge passes Cypress firefox
locally. Absolutely boggled by this.

AAAAAAAAAAAAAAA

* fix: separate the test

Okay apparently the test does not work unless we separate it into
a different `it` statement.

--description--

dispatch 方法用於將 action 分派給 Redux store 調用 store.dispatch() 將從 action creator 返回的值發送回 store。

回想一下,動作創建者返回一個具有 type 屬性的對象,該屬性指定已發生的動作。 然後該方法會將一個 action 對象發送到 Redux store。 基於上一個挑戰的示例,下面的行是等效的,兩者都會調度類 LOGIN 類型的 action

store.dispatch(actionCreator());
store.dispatch({ type: 'LOGIN' });

--instructions--

代碼編輯器中的 Redux store 具有初始化狀過的 state包含 login 屬性當前設置爲 false的對象, 還有一個名爲 loginAction() 的 action creator它返回類型爲 LOGIN 的 action 然後通過調用 dispatch 方法將 LOGIN 的 action dispatch 給 Redux store並傳入 loginAction() 創建的 action。

--hints--

調用函數 loginAction 應該返回一個 type 屬性設置爲字符串 LOGIN 的對象。

assert(loginAction().type === 'LOGIN');

store 應該用屬性 login 設置爲 false 的對象初始化。

assert(store.getState().login === false);

store.dispatch() 方法應該被用於 dispatch 一個類型爲 LOGIN 的 action。

(getUserInput) =>
  assert(
    (function () {
      let noWhiteSpace = getUserInput('index').replace(/\s/g, '');
      return (
        noWhiteSpace.includes('store.dispatch(loginAction())') ||
        noWhiteSpace.includes("store.dispatch({type: 'LOGIN'})") === true
      );
    })()
  );

--seed--

--seed-contents--

const store = Redux.createStore(
  (state = {login: false}) => state
);

const loginAction = () => {
  return {
    type: 'LOGIN'
  }
};

// Dispatch the action here:

--solutions--

const store = Redux.createStore(
  (state = {login: false}) => state
);

const loginAction = () => {
  return {
    type: 'LOGIN'
  }
};

store.dispatch(loginAction());
