## Description
<section id='description'>
请注意，本项目在 <a href="https://repl.it/github/freeCodeCamp/boilerplate-mochachai">这个 Repl.it 项目</a> 的基础上进行开发。你也可以从 <a href='https://repl.it/github/freeCodeCamp/boilerplate-mochachai'>GitHub</a> 上克隆。
<code>strictEqual()</code> 使用 <code>===</code> 比较对象。
</section>

## Instructions
<section id='instructions'>
使用 <code>assert.strictEqual()</code> 或 <code>assert.notStrictEqual()</code> 让所有测试通过。

</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: 不应有未通过的测试
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(data => {assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—strictEqual 或 notStrictEqual
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(data => {  assert.equal(data.assertions[0].method, 'notStrictEqual', 'with strictEqual the type must match'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—strictEqual 或 notStrictEqual
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(data => {  assert.equal(data.assertions[1].method, 'strictEqual', '3*2 = 6...'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—strictEqual 或 notStrictEqual
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(data => {  assert.equal(data.assertions[2].method, 'strictEqual', '6 * \'2\' is 12. Types match !'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—strictEqual 或 notStrictEqual
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(data => {  assert.equal(data.assertions[3].method, 'notStrictEqual', 'Even if they have the same elements, the Arrays are notStrictEqual'); }, xhr => { throw new Error(xhr.responseText); })
