# --description--

请注意，本项目在[这个 Replit 项目](https://replit.com/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。

`deepEqual()` 断言两个对象是否深度相等。

# --instructions--

在 `tests/1_unit-tests.js` 中，在标有 `#7` 的 `Equality` 套件里，将每个 `assert` 替换成 `assert.deepEqual` 或 `assert.notDeepEqual`，让测试通过（应该返回 `true`）。 不要改变传入断言的参数。

# --hints--

不应有未通过的测试

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=6').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

请为第一个断言选择正确的方法 — `deepEqual` 或 `notDeepEqual`。

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=6').then(
    (data) => {
      assert.equal(
        data.assertions[0].method,
        'deepEqual',
        'The order of the keys does not matter'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

请为第二个断言选择正确的方法 — `deepEqual` 或 `notDeepEqual`。

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=6').then(
    (data) => {
      assert.equal(
        data.assertions[1].method,
        'notDeepEqual',
        'The position of elements within an array does matter'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```
