# --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。
當你測試一個 `PUT` 請求時,你經常會隨同它一起發送數據。 你在 `PUT` 請求中包含的數據被稱爲請求的主體。
要將 `PUT` 請求和 JSON 對象發送到 `'/travellers'` 端點,你可以使用 `chai-http` 插件的 `put``send` 方法:
```js
chai
.request(server)
.put('/travellers')
.send({
"surname": [last name of a traveller of the past]
})
...
```
並且路由響應如下:
```json
{
"name": [first name],
"surname": [last name],
"dates": [birth - death years]
}
```
請參閱服務器代碼以瞭解對 `'/travellers'` 端點的不同響應。
# --instructions--
`tests/2_functional-tests.js` 中,更改 `'Send {surname: "Colombo"}'` 測試(`// #3`),並使用 `put``send` 方法來測試 `'/travellers'` 端點。
在你的 PUT 請求中發送以下 JSON 對象。
```json
{
"surname": "Colombo"
}
```
`request.end` 的返回中檢查以下情況:
1. `status` 應該是 `200`
2. `type` 應該是 `application/json`
3. `body.name` 應該是 `Cristoforo`
4. `body.surname` 應該是 `Colombo`
請按照以上順序書寫斷言,順序錯誤會影響系統判定。 此外,請確保在完成後刪除 `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);
}
);
```
應該測試 `res.status` 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);
}
);
```
應該測試 `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);
}
);
```
你應該測試 `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);
}
);
```
你應該測試 `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);
}
);
```
