# --description--
请注意,本项目在[这个 Replit 项目](https://replit.com/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。
# --instructions--
`tests/2_functional-tests.js` 中,在 `'Submit the surname "Vespucci" in the HTML form'` 测试(`// #5`),自动执行以下操作:
1. 在表格中填写姓氏 `Vespucci`
2. 点击提交按钮
`pressButton` 回调中:
1. 断言状态是正常的 `200`
2. 断言元素 `span#name` 中的文本是 `'Amerigo'`
3. 断言元素 `span#surname` 元素中的文本是 `'Vespucci'`
4. 断言有 `span#dates` 元素,它们的计数是 `1`
不要忘记删除 `assert.fail()` 调用。
# --hints--
应通过所有测试。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=6').then(
(data) => {
assert.equal(data.state, 'passed');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
应断言无头浏览器成功执行请求。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=6').then(
(data) => {
assert.equal(data.assertions[0].method, 'browser.success');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
应断言元素 `span#name` 中的文本是 `'Amerigo'`
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=6').then(
(data) => {
assert.equal(data.assertions[1].method, 'browser.text');
assert.match(data.assertions[1].args[0], /('|")span#name\1/);
assert.match(data.assertions[1].args[1], /('|")Amerigo\1/);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
应断言元素 `span#surname` 中的文本是 `'Vespucci'`
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=6').then(
(data) => {
assert.equal(data.assertions[2].method, 'browser.text');
assert.match(data.assertions[2].args[0], /('|")span#surname\1/);
assert.match(data.assertions[2].args[1], /('|")Vespucci\1/);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
应该断言元素 `span#dates` 存在,且它的值为 1。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=6').then(
(data) => {
assert.equal(data.assertions[3].method, 'browser.elements');
assert.match(data.assertions[3].args[0], /('|")span#dates\1/);
assert.equal(data.assertions[3].args[1], 1);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
