# --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。

`match()` 断言一个值匹配一个正则表达式（第二个参数）。

# --instructions--

使用 `assert.match()` 让所有测试通过。

# --hints--

不应有未通过的测试

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=14').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

请选择正确的断言—match 或 notMatch

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=14').then(
    (data) => {
      assert.equal(
        data.assertions[0].method,
        'match',
        "'# name: John Doe, age: 35' matches the regex"
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

请选择正确的断言—match 或 notMatch

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=14').then(
    (data) => {
      assert.equal(
        data.assertions[1].method,
        'notMatch',
        "'# name: Paul Smith III, age: twenty-four' does not match the regex (the age must be numeric)"
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```
