# --description--
|
||
|
||
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。

||
|
||
`isOk()` 用来测试值是否为 `truthy`；`isNotOk()` 用来测试值是否为 `falsy`。 如果你想了解更多关于 truthy 和 falsy 值的内容，请参阅 [Falsy Bouncer](https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/basic-algorithm-scripting/falsy-bouncer) 这道挑战题目。
|
||
|
||
# --instructions--
|
||
|
||
使用 `assert.isOk()` 或 `assert.isNotOk()` 让测试通过。
|
||
|
||
# --hints--
|
||
|
||
不应有未通过的测试
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=2').then(
|
||
(data) => {
|
||
assert.equal(data.state, 'passed');
|
||
},
|
||
(xhr) => {
|
||
throw new Error(xhr.responseText);
|
||
}
|
||
);
|
||
```
|
||
|
||
请选择正确的断言—isOk 或 isNotOk
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=2').then(
|
||
(data) => {
|
||
assert.equal(data.assertions[0].method, 'isNotOk', 'Null is falsy');
|
||
},
|
||
(xhr) => {
|
||
throw new Error(xhr.responseText);
|
||
}
|
||
);
|
||
```
