# --description--
|
||
|
||
请注意，本项目在 [这个 Repl.it 项目](https://repl.it/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。
|
||
|
||
接下来，我们将了解如何使用请求的 payload（body）发送数据。 我们需要测试一个 PUT 请求， `'/travellers'` 接收如下的 JSON 对象：
|
||
|
||
```json
|
||
{
|
||
"surname": [last name of a traveller of the past]
|
||
}
|
||
```
|
||
|
||
路由响应如下：
|
||
|
||
```json
|
||
{
|
||
"name": [first name], "surname": [last name], "dates": [birth - death years]
|
||
}
|
||
```
|
||
|
||
更多细节请查看服务器代码。
|
||
|
||
# --instructions--
|
||
|
||
在 `tests/2_functional-tests.js` 中，修改 `'send {surname: "Colombo"}'` 测试（`// #3`）：
|
||
|
||
发送以下 JSON 响应作为有效载荷：
|
||
|
||
```json
|
||
{
|
||
"surname": "Colombo"
|
||
}
|
||
```
|
||
|
||
在 `request.end` 返回中检查以下情况：
|
||
|
||
1. `status`
|
||
2. `type`
|
||
3. `body.name`
|
||
4. `body.surname`
|
||
|
||
请按照以上顺序书写断言，顺序错误会影响系统判定。 完成后，请务必移除 `assert.fail()`。
|
||
|
||
# --hints--
|
||
|
||
应通过所有测试。
|
||
|
||
```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);
|
||
}
|
||
);
|
||
```
|
||
|
||
应测试 “res.status” 是否为 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);
|
||
}
|
||
);
|
||
```
|
||
|
||
需要测试 “res.type” 是否为 “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);
|
||
}
|
||
);
|
||
```
|
||
|
||
需要测试 “res.body.name” 是否为 “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);
|
||
}
|
||
);
|
||
```
|
||
|
||
需要测试 “res.body.surname” 是否为 “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);
|
||
}
|
||
);
|
||
```
