## Tests
<section id='tests'>
# --hints--
```yml
tests:
- text: <code>hofstadterQ</code>是一个函数。
testString: assert(typeof hofstadterQ === 'function');
- text: <code>hofstadterQ()</code>应该返回<code>integer</code>
testString: assert(Number.isInteger(hofstadterQ(1000)));
- text: <code>hofstadterQ(1000)</code>应该返回<code>502</code>
testString: assert.equal(hofstadterQ(testCase[0]), res[0]);
- text: <code>hofstadterQ(1500)</code>应该返回<code>755</code>
testString: assert.equal(hofstadterQ(testCase[1]), res[1]);
- text: <code>hofstadterQ(2000)</code>应该返回<code>1005</code>
testString: assert.equal(hofstadterQ(testCase[2]), res[2]);
- text: <code>hofstadterQ(2500)</code>应该返回<code>1261</code>
testString: assert.equal(hofstadterQ(testCase[3]), res[3]);
```
</section>
## Challenge Seed
<section id='challengeSeed'>
<div id='js-seed'>
`hofstadterQ`是一个函数。
```js
function hofstadterQ (n) {
// Good luck!
return n;
}
assert(typeof hofstadterQ === 'function');
```
</div>
### After Test
<div id='js-teardown'>
`hofstadterQ()`应该返回`integer`
```js
console.info('after the test');
assert(Number.isInteger(hofstadterQ(1000)));
```
</div>
</section>
## Solution
<section id='solution'>
`hofstadterQ(1000)`应该返回`502`
```js
// solution required
assert.equal(hofstadterQ(testCase[0]), res[0]);
```
/section>
`hofstadterQ(1500)`应该返回`755`
```js
assert.equal(hofstadterQ(testCase[1]), res[1]);
```
`hofstadterQ(2000)`应该返回`1005`
```js
assert.equal(hofstadterQ(testCase[2]), res[2]);
```
`hofstadterQ(2500)`应该返回`1261`
```js
assert.equal(hofstadterQ(testCase[3]), res[3]);
```
