* 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.

title: 提供静态资源服务

# --description--
HTML 服务器通常有一个或多个用户可以访问的目录。 你可以将应用程序所需的静态资源 (样式表、脚本、图片) 放在那里。
在 Express 中可以使用中间件 `express.static(path)` 来设置此功能,它的参数 `path` 就是包含静态资源文件的绝对路径。
如果你不知道什么是中间件……别担心,我们将在后面详细讨论。 其实,中间件就是一个拦截路由处理方法并在里面添加一些信息的函数。 使用 `app.use(path, middlewareFunction)` 方法来加载一个中间件, 它的第一个参数 `path` 是可选的, 如果没设置第一个参数,那么所有的请求都会经过这个中间件处理。
# --instructions--
使用 `app.use()` 为路径 `/public` 的请求安装 `express.static()` 中间件, 静态资源的绝对路径是 `__dirname + /public`
现在应用应该能提供 CSS 样式表, 请注意, `/public/style.css` 文件被项目模板的 `/views/index.html` 引用, 首页应该更好看了。
# --hints--
应用应该将资源文件从 `/public` 目录发送到 `/public` 路径
```js
(getUserInput) =>
$.get(getUserInput('url') + '/public/style.css').then(
(data) => {
assert.match(
data,
/body\s*\{[^\}]*\}/,
'Your app does not serve static assets'
);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
# --solutions--

/**
Backend challenges don't need solutions,
because they would need to be tested against a full working project.
