* 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 方法用于将 action 分派给 Redux store 调用 store.dispatch() 将从 action creator 返回的值发送回 store。

回想一下,动作创建者返回一个具有 type 属性的对象,该属性指定已发生的动作。 然后该方法会将一个 action 对象发送到 Redux store。 基于上一个挑战的示例,下面的行是等效的,两者都会调度类 LOGIN 类型的 action

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

--instructions--

代码编辑器中的 Redux store 具有初始化状过的 state包含 login 属性当前设置为 false的对象, 还有一个名为 loginAction() 的 action creator它返回类型为 LOGIN 的 action 然后通过调用 dispatch 方法将 LOGIN 的 action dispatch 给 Redux store并传入 loginAction() 创建的 action。

--hints--

调用函数 loginAction 应该返回一个 type 属性设置为字符串 LOGIN 的对象。

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

store 应该用属性 login 设置为 false 的对象初始化。

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

store.dispatch() 方法应该被用于 dispatch 一个类型为 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());
