請注意，本項目在[這個 Replit 項目](https://replit.com/github/freeCodeCamp/boilerplate-mochachai)的基礎上進行開發。你也可以從 [GitHub](https://repl.it/github/freeCodeCamp/boilerplate-mochachai) 上克隆。

# --instructions--
|
|
|
|
在 `tests/1_unit-tests.js` 中，在標有 `#8` 的 `Comparisons` 套件裏，將每個 `assert` 改成 `assert.isAbove` 或 `assert.isAtMost` 方法，讓測試通過（結果應該返回 `true`）。 不要改變傳入斷言的參數。
|
|
|
|
# --hints--
|
|
|
|
不應有未通過的測試
|

|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
|
|
(data) => {
|
|
assert.equal(data.state, 'passed');
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
請爲第一個斷言選擇正確的方法 — `isAbove` 或 `isAtMost`。
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
|
|
(data) => {
|
|
assert.equal(
|
|
data.assertions[0].method,
|
|
'isAtMost',
|
|
'5 is at most (<=) 5'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
請爲第二個斷言選擇正確的方法 — `isAbove` 或 `isAtMost`。
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
|
|
(data) => {
|
|
assert.equal(data.assertions[1].method, 'isAbove', '1 is greater than 0');
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
請爲第三個斷言選擇正確的方法 — `isAbove` 或 `isAtMost`。
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
|
|
(data) => {
|
|
assert.equal(
|
|
data.assertions[2].method,
|
|
'isAbove',
|
|
'Math.PI = 3.14159265 is greater than 3'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
請爲第四個斷言選擇正確的方法 — `isAbove` 或 `isAtMost`。
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
|
|
(data) => {
|
|
assert.equal(
|
|
data.assertions[3].method,
|
|
'isAtMost',
|
|
'1 - Math.random() is > 0 and <= 1. It is atMost 1 !'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
