title: 使用 Assert.isOk() 和 Assert.isNotOK()
challengeType: 2
forumTopicId: 301607

# --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);
    }
  );
```

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[1].method, 'isOk', 'A string is truthy');
    },
    (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[2].method, 'isOk', 'true is truthy');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```
