+
+## Setup
+Create a Joomla website in your local web server.
+
+Go to the folder where your website is located and run:
+
+```bash
+composer require codeception/codeception --dev
+```
+
+Then run:
+
+```
+vendor/bin/codecept bootstrap --empty
+```
+
+Previous command will have createed `codeception.yml` and `tests` directory.
+
+### Acceptance Testing
+
+#### Using headless browser
+
+To test the User Interface of a Joomla Template or an Extension (plugin, module, component, language pack,...) you should simulate the user interaction with a browser.
+
+For UI testing you will the first step will be to create an  acceptance tests suite:
+
+```
+vendor/bin/codecept generate:suite acceptance
+```
+
+This will create `acceptance.suite.yml` and `acceptance` folder inside `tests`. 
+
+```yaml
+class_name: AcceptanceTester
+modules:
+    enabled:
+        - PhpBrowser:
+            url: http://joomla.box/codeception/
+        - \Helper\Acceptance          
+```
+
+Acceptance tests should be described in Cest format. Run Cest test generator to generate your very first test `tests/acceptance/AdminLoginCest.php`: 
+
+```
+vendor/bin/codecept generate:cest acceptance AdminLoginCest
+```
+
+Each method of a Cest class (except `_before` and `_after`) is a test. Tests use `$I` object (instance of `AcceptanceTester` class) to perform actions on a webpage. 
+
+Modify your `tests/acceptance/AdminLoginCest.php` using the following example code:
+
+```php
+<?php
+
+class AdminLoginCest
+{
+    public function login(AcceptanceTester $I)
+    {
+        $I->amOnPage('/administrator/index.php');
+        $I->comment('Fill Username Text Field');
+        $I->fillField('#mod-login-username', 'admin');
+        $I->comment('Fill Password Text Field');
+        $I->fillField('#mod-login-password', 'admin');
+        $I->comment('I click Login button');
+        $I->click('Log in');
+        $I->comment('I see Administrator Control Panel');
+        $I->see('Control Panel', '.page-title');
+    }
+}
+```
+
+To generate method stubs for `AcceptanceTester` run:
+
+```
+vendor/bin/codecept build
+```
+
+Now you are able to run your first test:
+
+
+```
+vendor/bin/codecept run acceptance
+```
+
+Or, try this command to see the execution step by step:
+
+```
+vendor/bin/codecept run acceptance --steps
+```
+
+#### Using a real browser
+
+Previous execution was done using a headless browser: PHPBrowser.  This is the fastest way to run User Interface tests since it doesn’t require running an actual browser. Instead, uses a PHP web scraper, which acts like a browser (it sends a request, then receives and parses the response). Read more about PHPBrowser at [http://codeception.com/docs/03-AcceptanceTests#PHP-Browser](http://codeception.com/docs/03-AcceptanceTests#PHP-Browser).
+
+If you prefer to run your test on a real browser like Firefox you are required to use the Codeception Webdriver Module. Unlike PHPBrowser it will allow you to test the visibility of elements or test javascript interactions (but the test execution will be considerably slower).
+
+The Joomla Community provides an extended Webdriver Codeception Module called [Joomla-Browser](http://codeception.com/addons#Joomla-Browser). With Joomla-Browser you can execute, with one command, common joomla actions like: install Joomla, do Adminitrator Login, publish a module, and many more. See the full list at [Joomla Browser Documentation](https://github.com/joomla-projects/joomla-browser#joomla-browser-codeception-module).
+
+In the following example we are going to refactor our previous "administrator login test" by using Joomla-Browser and executing it in a Firefox browser:
+
+First, install Joomla-browser:
+
+```bash
+composer require joomla-projects/joomla-browser --dev
+```
+
+Modify your acceptance.suite.yml file like as follows:
+
+```yaml
+class_name: AcceptanceTester
+modules:
+    enabled:
+        - JoomlaBrowser
+        - AcceptanceHelper
+    config:
+        JoomlaBrowser:
+            url: 'http://localhost/tests/joomla-cms3'     # the url that points to the joomla installation at /tests/system/joomla-cms
+            browser: 'firefox'
+            window_size: 1024x768
+            capabilities:
+              unexpectedAlertBehaviour: 'accept'
+            username: 'admin'                      # UserName for the Administrator
+            password: 'admin'                      # Password for the Administrator
+            database host: 'localhost'             # place where the Application is Hosted #server Address
+            database user: 'root'                  # MySQL Server user ID, usually root
+            database password: ''                  # MySQL Server password, usually empty or root
+            database name: 'testjoomla'            # DB Name, at the Server
+            database type: 'mysqli'                # type in lowercase one of the options: MySQL\MySQLi\PDO
+            database prefix: 'jos_'                # DB Prefix for tables
+            install sample data: 'No'              # Do you want to Download the Sample Data Along with Joomla Installation, then keep it Yes
+            sample data: 'Default English (GB) Sample Data'    # Default Sample Data
+            admin email: 'admin@mydomain.com'      # email Id of the Admin
+            language: 'English (United Kingdom)'   # Language in which you want the Application to be Installed
+            joomla folder: 'home/.../path to Joomla Folder' # Path to Joomla installation where we execute the tests
+
+```
+
+Modify your previous `tests/acceptance/AdminLoginCest.php` using the following example code:
+
+```php
+<?php
+
+class AdminLoginCest
+{
+    public function login(AcceptanceTester $I)
+    {
+        $I->doAdministratorLogin();
+    }
+}
+```
+
+Run the test:
+
+```
+vendor/bin/codecept run acceptance --steps
+```
+
+**Important note**, in order to run the previous test you need to have [Selenium](http://docs.seleniumhq.org/download/) running in your system. If you are new to Selenium, you can find an example of useage at the [Weblinks Joomla Official supported extension](https://github.com/joomla-extensions/weblinks#tests). Just follow the "running the tests" instructions to learn how to easily lauch Selenium in your system.

+### BDD
+
+If you prefer to describe application with feature files, Codeception can turn them to acceptance tests.
+
+Your previous test would look like:
+
+```gherkin
+Feature: administrator login
+  In order to manage my web application
+  As administrator
+  I need to be able to login
+
+  Scenario: Successful login
+    Given I am registered administrator named "admin"
+    When I login into Joomla Administrator with username "admin" and password "admin"
+    Then I should see administrator dashboard
+```
