# --description--
|
|
|
|
As a reminder, this project is being built upon the following starter project on [Replit](https://replit.com/github/freeCodeCamp/boilerplate-mochachai), or cloned from [GitHub](https://github.com/freeCodeCamp/boilerplate-mochachai/).
|
|
|
|
In the HTML main view we provided a input form. It sends data to the `PUT /travellers` endpoint that we used above with an Ajax request. When the request successfully completes, the client code appends a `<div>` containing the info returned by the call to the DOM. Here is an example of how to interact with this form:
|
|
|
|
```js
|
|
test('#test - submit the input "surname" : "Polo"', function (done) {
|
|
browser.fill('surname', 'Polo').pressButton('submit', function () {
|
|
browser.assert.success();
|
|
browser.assert.text('span#name', 'Marco');
|
|
browser.assert.text('span#surname', 'Polo');
|
|
browser.assert.elements('span#dates', 1);
|
|
done();
|
|
});
|
|
}
|
|
```
|
|
|
|
First, the `fill` method of the `browser` object fills the `surname` field of the form with the value `'Polo'`. Immediately after, the `pressButton` method invokes the `submit` event listener of the form. The `pressButton` method is asynchronous.
|
|
|
|
Then, once a response is received from the AJAX request, a few assertions are made confirming:
|
|
|
|
1. The status of the response is `200`
|
|
2. The text within the `<span id='name'></span>` element matches `'Marco'`
|
|
3. The text within the `<span id='surname'></span>` element matches `'Polo'`
|
|
4. There is `1` `<span id='dates'></span>` element.
|
|
|
|
Finally, the `done` callback is invoked, which is needed due to the asynchronous test.
|
|
|
|
# --instructions--
|
|
|
|
Within `tests/2_functional-tests.js`, in the `'submit "surname" : "Colombo" - write your e2e test...'` test (`// #5`), automate filling-in and submitting the form:
|
|
|
|
1. Fill in the form
|
|
2. Submit it pressing `'submit'` button.
|
|
|
|
Within the callback:
|
|
|
|
1. assert that status is OK `200`
|
|
2. assert that the text inside the element `span#name` is `'Cristoforo'`
|
|
3. assert that the text inside the element `span#surname` is `'Colombo'`
|
|
4. assert that the element(s) `span#dates` exist and their count is `1`
|
|
|
|
Do not forget to remove the `assert.fail()` call.
|
|
|
|
# --hints--
|
|
|
|
All tests should pass.
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=4').then(
|
|
(data) => {
|
|
assert.equal(data.state, 'passed');
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
You should assert that the headless browser request succeeded.
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=4').then(
|
|
(data) => {
|
|
assert.equal(data.assertions[0].method, 'browser.success');
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
You should assert that the text inside the element 'span#name' is 'Cristoforo'.
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=4').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], /('|")Cristoforo\1/);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
You should assert that the text inside the element 'span#surname' is 'Colombo'.
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=4').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], /('|")Colombo\1/);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
You should assert that the element 'span#dates' exist and its count is 1.
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=4').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);
|
|
}
|
|
);
|
|
```
