# --description--
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。 這個練習與上一個類似, 我們詳細看看。
你已經看到了它是如何完成的,現在你需要從零開始搭建。
# --instructions--
`tests/2_functional-tests.js` 中,修改 `'send {surname: "da Verrazzano"}'` 測試(`// #4`)。
發送以下 JSON 響應作爲有效載荷到 `/travellers` 路徑:
```json
{
"surname": "da Verrazzano"
}
```
`request.end` 返回中檢查以下情況:
1. `status`
2. `type`
3. `body.name`
4. `body.surname`
請按照以上順序書寫斷言,順序錯誤會影響系統判定。 完成後請務必刪除 `assert.fail()`
# --hints--
需要通過所有測試。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=3').then(
(data) => {
assert.equal(data.state, 'passed');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
需要測試 “res.status” 是否爲 200。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=3').then(
(data) => {
assert.equal(data.assertions[0].method, 'equal');
assert.equal(data.assertions[0].args[0], 'res.status');
assert.equal(data.assertions[0].args[1], '200');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
需要測試 “res.type” 是否爲 “application/json”。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=3').then(
(data) => {
assert.equal(data.assertions[1].method, 'equal');
assert.equal(data.assertions[1].args[0], 'res.type');
assert.match(data.assertions[1].args[1], /('|")application\/json\1/);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
需要測試 “res.body.name” 爲 “Giovanni”。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=3').then(
(data) => {
assert.equal(data.assertions[2].method, 'equal');
assert.equal(data.assertions[2].args[0], 'res.body.name');
assert.match(data.assertions[2].args[1], /('|")Giovanni\1/);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
需要測試 “res.body.surname” 是否爲 “da Verrazzano”。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=3').then(
(data) => {
assert.equal(data.assertions[3].method, 'equal');
assert.equal(data.assertions[3].args[0], 'res.body.surname');
assert.match(data.assertions[3].args[1], /('|")da Verrazzano\1/);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
