# --description--

请注意，本项目在 [这个 Repl.it 项目](https://repl.it/github/freeCodeCamp/boilerplate-mochachai) 的基础上进行开发。你也可以从 [GitHub](https://repl.it/github/freeCodeCamp/boilerplate-mochachai) 上克隆。

# --instructions--

此挑战与之前的挑战十分类似。

请阅读此挑战给出的代码指引，按顺序书写断言。顺序错误会影响此挑战的判定。

# --hints--

不应有未通过的测试

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=5').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

Headless browser 应成功执行请求

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=5').then(
    (data) => {
      assert.equal(data.assertions[0].method, 'browser.success');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

元素 'span#name' 中的文字应为 'Amerigo'.

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=5').then(
    (data) => {
      assert.equal(data.assertions[1].method, 'browser.text');
      assert.match(data.assertions[1].args[0], /('|")span#name\1/);
      assert.match(data.assertions[1].args[1], /('|")Amerigo\1/);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

元素 'span#surname' 中的文字应为 'Vespucci'.

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=5').then(
    (data) => {
      assert.equal(data.assertions[2].method, 'browser.text');
      assert.match(data.assertions[2].args[0], /('|")span#surname\1/);
      assert.match(data.assertions[2].args[1], /('|")Vespucci\1/);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

元素 'span#dates' 应存在，并且只有一个

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=5').then(
    (data) => {
      assert.equal(data.assertions[3].method, 'browser.element');
      assert.match(data.assertions[3].args[0], /('|")span#dates\1/);
      assert.equal(data.assertions[3].args[1], 1);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```
