# --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。
|
||
|
||
接下來，我們將瞭解如何使用請求的 payload（body）發送數據。 我們需要測試一個 PUT 請求， `'/travellers'` 接收如下的 JSON 對象：
|
||
|
||
```json
|
||
{
|
||
"surname": [last name of a traveller of the past]
|
||
}
|
||
```
|
||
|
||
路由響應如下：
|
||
|
||
```json
|
||
{
|
||
"name": [first name], "surname": [last name], "dates": [birth - death years]
|
||
}
|
||
```
|
||
|
||
更多細節請查看服務器代碼。
|
||
|
||
# --instructions--
|
||
|
||
在 `tests/2_functional-tests.js` 中，修改 `'send {surname: "Colombo"}'` 測試（`// #3`）：
|
||
|
||
發送以下 JSON 響應作爲有效載荷：
|
||
|
||
```json
|
||
{
|
||
"surname": "Colombo"
|
||
}
|
||
```
|
||
|
||
在 `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，請務必移除 `assert.fail()`。
|
||
|
||
# --hints--
|
||
|
||
應通過所有測試。
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').then(
|
||
(data) => {
|
||
assert.equal(data.state, 'passed');
|
||
},
|
||
(xhr) => {
|
||
throw new Error(xhr.responseText);
|
||
}
|
||
);
|
||
```
|
||
|
||
應測試 “res.status” 是否爲 200。
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').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=2').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” 是否爲 “Cristoforo”。
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').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], /('|")Cristoforo\1/);
|
||
},
|
||
(xhr) => {
|
||
throw new Error(xhr.responseText);
|
||
}
|
||
);
|
||
```
|
||
|
||
需要測試 “res.body.surname” 是否爲 “Colombo”。
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').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], /('|")Colombo\1/);
|
||
},
|
||
(xhr) => {
|
||
throw new Error(xhr.responseText);
|
||
}
|
||
);
|
||
```
