## 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。

## 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=14').then(data => { assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—match 或 notMatch
    testString: '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); })'
  - text: 请选择正确的断言—match 或 notMatch
    testString: '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); })'
