* add forwards slashes to path redirects

* fix cypress path tests again

* 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.

title: 在 JSX 中定義一個 HTML Class
challengeType: 6
forumTopicId: 301393
dashedName: define-an-html-class-in-jsx
---
# --description--
現在已經習慣了編寫 JSX可能想知道它與 HTML 有什麼不同。
到目前爲止HTML 和 JSX 似乎完全相同。
JSX 的一個關鍵區別是你不能再使用 `class` 這個單詞來做爲 HTML 的 class 名。 這是因爲 `class` 是 JavaScript 中的關鍵字。 而 JSX 使用 `className` 來代替。
事實上JSX 中所有 HTML 屬性和事件引用的命名約定都變成了駝峯式。 例如JSX 中的單擊事件是 `onClick`,而不是 `onclick`。 同樣,`onchange` 變成了`onChange`。 雖然這是一個微小的差異,但請你一定要記住。
# --instructions--
將 class `myDiv` 應用於 JSX 提供的 `div`上。
# --hints--
常量`JSX`應該返回一個`div`元素。
```js
assert.strictEqual(JSX.type, 'div');
```
`div` 應該有一個 `myDiv` class。
```js
assert.strictEqual(JSX.props.className, 'myDiv');
```
# --seed--
## --after-user-code--
```jsx
ReactDOM.render(JSX, document.getElementById('root'))
```
## --seed-contents--
```jsx
const JSX = (
<div>
<h1>Add a class to this div</h1>
</div>
);
```
# --solutions--
```jsx
const JSX = (
<div className = 'myDiv'>
<h1>Add a class to this div</h1>
</div>);
```
