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。

|
|
`equal()` 使用 `==` 比较对象。
|
|
|
|
# --instructions--
|
|
|
|
使用 `assert.equal()` 或 `assert.notEqual()` 让所有测试通过。
|
|
|
|
# --hints--
|
|
|
|
不应有未通过的测试

```js

|
(data) => {
|
|
assert.equal(data.state, 'passed');
