| # --description--
 | |
| 
 | |
| As a reminder, this project is being built upon the following starter project on [Repl.it](https://repl.it/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.element('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.  The 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.element');
 | |
|       assert.match(data.assertions[3].args[0], /('|")span#dates\1/);
 | |
|       assert.equal(data.assertions[3].args[1], 1);
 | |
|     },
 | |
|     (xhr) => {
 | |
|       throw new Error(xhr.responseText);
 | |
|     }
 | |
|   );
 | |
| ```
