# --description--

As a reminder, this project is being built upon the following starter project cloned from <a href="https://github.com/freeCodeCamp/boilerplate-mochachai/" target="_blank" rel="noopener noreferrer nofollow">GitHub</a>.

`deepEqual()` asserts that two objects are deep equal.

# --instructions--

Within `tests/1_unit-tests.js` under the test labeled `#7` in the `Equality` suite, change each `assert` to either `assert.deepEqual` or `assert.notDeepEqual` to make the test pass (should evaluate to `true`). Do not alter the arguments passed to the asserts.

# --hints--

All tests should pass.

```js
(async () => {
  const response = await fetch(code + '/_api/get-tests?type=unit&n=6');
  if (!response.ok) {
    throw new Error(await response.text());
  }
  const data = await response.json();
  assert.equal(data.state, 'passed');
})();
```

You should choose the correct method for the first assertion - `deepEqual` vs. `notDeepEqual`.

```js
(async () => {
  const response = await fetch(code + '/_api/get-tests?type=unit&n=6');
  if (!response.ok) {
    throw new Error(await response.text());
  }
  const data = await response.json();
  assert.equal(
    data.assertions[0].method,
    'deepEqual',
    'The order of the keys does not matter'
  );
})();
```

You should choose the correct method for the second assertion - `deepEqual` vs. `notDeepEqual`.

```js
(async () => {
  const response = await fetch(code + '/_api/get-tests?type=unit&n=6');
  if (!response.ok) {
    throw new Error(await response.text());
  }
  const data = await response.json();
  assert.equal(
    data.assertions[1].method,
    'notDeepEqual',
    'The position of elements within an array does matter'
  );
})();
```
