	+In-Browser Tests
	+================
	+
	+The idea of these testing suite is to make it as simple as possible to execute
	+the tests. So, you don't have to run any additional services, nor download
	+and install anything manually.
	+
	+The tests are using [Laravel Dusk][laravel-dusk] and Chrome WebDriver.
	+PHP server is used to serve Roundcube instance on tests run.
	+
	+
	+INSTALLATION
	+------------
	+
	+Installation:
	+
	+1. Add `"laravel/dusk": "~5.7.0"` to your composer.json file and run `composer update`.
	+2. Install Chrome WebDriver for the version of Chrome/Chromium in your system. Yes,
	+ you have to have Chrome/Chromium installed.
	+```
	+php tests/Browser/install.php [version]`
	+```
	+3. Configure the test account and Roundcube instance.
	+
	+Create a config file named `config-test.inc.php` in the Roundcube config dir.
	+That file should provide specific `db_dsnw` and
	+`default_host` values for testing purposes as well as the credentials of a
	+valid IMAP user account used for running the tests with.
	+
	+Add these config options used by the Browser tests:
	+
	+```php
	+ // Unit tests settings
	+ $config['tests_username'] = 'roundcube.test@example.org';
	+ $config['tests_password'] = '<test-account-password>';
	+```
	+
	+WARNING
	+-------
	+Please note that the configured IMAP account as well as the Roundcube database
	+configred in `db_dsnw` will be wiped and filled with test data in every test
	+run. Under no circumstances you should use credentials of a production database
	+or email account!
	+
	+Please, keep the file as simple as possible, i.e. containing only database
	+and imap/smtp settings needed for the test user authentication. We would
	+want to test default configuration. Especially only Elastic skin is supported.
	+
	+
	+EXECUTING THE TESTS
	+-------------------
	+
	+To run the test suite call `phpunit` from the tests/Browser directory:
	+
	+```
	+ cd <roundcube-dir>/tests/Browser
	+ phpunit # or ../../vendor/bin/phpunit
	+```

	-Running Selenium Tests
	-======================
	-
	-In order to run the Selenium-based web tests, some configuration for the
	-Roundcube test instance need to be created. Along with the default config for a
	-given Roundcube instance, you should provide a config specifically for running
	-tests. To do so, create a config file named `config-test.inc.php` in the
	-regular Roundcube config dir. That should provide specific `db_dsnw` and
	-`default_host` values for testing purposes as well as the credentials of a
	-valid IMAP user account used for running the tests with.
	-
	-Add these config options used by the Selenium tests:
	-
	-```php
	- // Unit tests settings
	- $config['tests_username'] = 'roundcube.test@example.org';
	- $config['tests_password'] = '<test-account-password>';
	- $config['tests_url'] = 'http://localhost/roundcube/index-test.php';
	-```
	-
	-The `tests_url` should point to Roundcube's index-test.php file accessible by
	-the Selenium web browser.
	-
	-WARNING
	--------
	-Please note that the configured IMAP account as well as the Roundcube database
	-configred in `db_dsnw` will be wiped and filled with test data in every test
	-run. Under no circumstances you should use credentials of a production database
	-or email account!
	-
	-
	-Run the tests
	--------------
	-
	-First you need to start a Selenium server. We recommend to use the
	-[Selenium Standalone Server][selenium-server] but the tests will also run on a
	-Selenium Grid. The tests are based in [PHPUnit_Selenium][phpunit] which can be
	-installed through [PEAR][pear-phpunit].
	-
	-To start the test suite call `phpunit` from the Selenium directory:
	-
	-```
	- cd <roundcube-dir>/tests/Selenium
	- phpunit
	-```
	-
	-[phpunit]: http://phpunit.de/manual/4.0/en/selenium.html
	-[pear-phpunit]: http://pear.phpunit.de/
