` 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 `
` element matches `'Marco'`
+3. The text within the `
` element matches `'Polo'`
+4. The there is `1` `
` element.
+
+Finally, the `done` callback is invoked, which is needed due to the asynchronous test.
+
## Instructions
+
-This exercise is similar to the preceding one.
-Look at the code for directions. Follow the assertions order: we rely on it.
+
+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 to remove the `assert.fail()` call.

## Description
+
+
As a reminder, this project is being built upon the following starter project on Repl.it, or cloned from GitHub.
+
In the next challenges we are going to simulate the human interaction with a page using a device called 'Headless Browser'.
+
A headless browser is a web browser without a graphical user interface. This kind of tool is particularly useful for testing web pages, as it is able to render and understand HTML, CSS, and JavaScript the same way a browser would.
+For these challenges we are using Zombie.JS. It's a lightweight browser which is totally based on JS, without relying on additional binaries to be installed. This feature makes it usable in an environment such as Repl.it. There are many other (more powerful) options.
+
+Mocha allows You to prepare the ground running some code before the actual tests. This can be useful for example to create items in the database, which will be used in the successive tests.
+
+With a headless browser, before the actual testing, we need to **visit** the page we are going to inspect. The `suiteSetup` 'hook' is executed only once at the suite startup. Other different hook types can be executed before each test, after each test, or at the end of a suite. See the Mocha docs for more information.
+

-For these challenges we are using Zombie.JS. It's a lightweight browser which is totally based on JS, without relying on additional binaries to be installed. This feature makes it usable in an environment such as Repl.it. There are many other (more powerful) options.
-Look at the examples in the code for the exercise directions Follow the assertions order, We rely on it.
+
+Within `tests/2_functional-tests.js`, immediately after the `Browser` declaration, add your project URL to the `site` property of the variable:
+
+```js
+Browser.site = 'https://sincere-cone.gomix.me'; // Your URL here
+```
+
+If you are testing on a local environment replace the line above with
+
+```js
+Browser.localhost('example.com', process.env.PORT || 3000);
+```
+
+Within `tests/2_functional-tests.js`, at the root level of the `'e2e Testing with Zombie.js'` suite, instantiate a new instance of the `Browser` object with the following code:
+
+```js
+const browser = new Browser();
+```
+
+Then, use the `suiteSetup` hook to direct the `browser` to the `/` route with the following code:
+
+```js
+suiteSetup(function(done) {
+ return browser.visit('/', done);
+});
+```

-equal() compares objects using ==.

+`equal()` compares objects using `==`.
+
## Instructions
+
-Use assert.equal() or assert.notEqual() to make the tests pass.
+
+Within `tests/1_unit-tests.js` under the test labelled `#5` in the `Equality` suite, change each `assert` to either `assert.equal` or `assert.notEqual` to make the test pass (should evaluate to `true`). Do not alter the arguments passed to the asserts.
## Tests
