# --description--
|
|
|
|
请注意，本项目在[这个 Replit 项目](https://replit.com/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。

# --instructions--
|
|
|
|
在 `tests/1_unit-tests.js` 中，在 `Comparisons` 套件里标有 `#9` 的测试中，将每个 `assert` 改成 `assert.isBelow` 或 `assert.isAtLeast` 方法，让测试通过（结果应该返回 `true`）。 不要修改传给断言的参数。
|
|
|
|
# --hints--
|
|
|
|
应通过所有测试。
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=8').then(
|
|
(data) => {
|
|
assert.equal(data.state, 'passed');
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
应该为第一个断言选择正确的方法：`isBelow` 或 `isAtLeast`。
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=8').then(
|
|
(data) => {
|
|
assert.equal(
|
|
data.assertions[0].method,
|
|
'isAtLeast',
|
|
'5 is at least (>=) 5'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
应该为第二个断言选择正确的方法：`isBelow` 或 `isAtLeast`。
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=8').then(
|
|
(data) => {
|
|
assert.equal(
|
|
data.assertions[1].method,
|
|
'isAtLeast',
|
|
'2 * Math.random() is at least 0'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
应该为第三个断言选择正确的方法：`isBelow` 或 `isAtLeast`。
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=8').then(
|
|
(data) => {
|
|
assert.equal(data.assertions[2].method, 'isBelow', '1 is smaller than 2');
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
应该为第四个断言选择正确的方法：`isBelow` 或 `isAtLeast`。
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=8').then(
|
|
(data) => {
|
|
assert.equal(
|
|
data.assertions[3].method,
|
|
'isBelow',
|
|
'2/3 (0.6666) is smaller than 1'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
