* 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--
+
+创建 action 后要将 action 发送到 Redux store，以便它可以更新其状态。 在 Redux 中，可以定义动作创建器来完成此任务， action creator 只是一个返回动作的 JavaScript 函数， 换句话说，action creator 创建表示动作事件的对象。
+
+# --instructions--
+
+定义名为 `actionCreator()` 的函数，该函数在调用时返回 `action` 对象。
+
+# --hints--
+
+函数 `actionCreator` 应该存在。
+
+```js
+assert(typeof actionCreator === 'function');
+```
+
+运行 `actionCreator` 函数应返回 `action` 对象。
+
+```js
+assert(typeof action === 'object');
+```
+
+返回的 `action` 对象应该有一个值为 `LOGIN` 的 `type` 属性。
+
+```js
+assert(action.type === 'LOGIN');
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+const action = {
+  type: 'LOGIN'
+}
+// Define an action creator here:
+```
+
+# --solutions--
+
+```js
+const action = {
+  type: 'LOGIN'
+}
+const actionCreator = () => {
+  return action;
+};
+```
