# --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。 这个练习与上一个类似, 我们详细看看。
你已经看到了它是如何完成的,现在你需要从零开始搭建。
# --instructions--
`tests/2_functional-tests.js` 中,修改 `'send {surname: "da Verrazzano"}'` 测试(`// #4`)。
发送以下 JSON 响应作为有效载荷到 `/travellers` 路径:
```json
{
"surname": "da Verrazzano"
}
```
`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。 完成后请务必删除 `assert.fail()`
# --hints--
需要通过所有测试。
```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);
}
);
```
需要测试 “res.status” 是否为 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);
}
);
```
需要测试 “res.type” 是否为 “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);
}
);
```
需要测试 “res.body.name” 为 “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);
}
);
```
需要测试 “res.body.surname” 是否为 “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);
}
);
