Requirements

PHP 5.6+ or newer
Composer
Java(JDK) >=1.8

Installation

Via composer.

$ composer require shimabox/screru
$ cd vendor/shimabox/screru
$ cp .env.default .env

Develop.

$ git clone https://github.com/shimabox/screru.git
$ cd screru
$ composer install

Copy the .env.default file and create an .env file.

Setting (.env | .env.default)

If you need to change the default settings, copy the .env.default file, create an .env file, and modify the .env file.
The default setting looks at .env.default file.

$ vim .env

Control the style of the element when scrolling the screen.
When you want to change the default selenium server url.

$ vim .env

// selenium server url
SELENIUM_SERVER_URL='your selenium server url'

When you want to change the default UserAgent.

$ vim .env

// you can override the default User-agent (Android 7.1.1)
OVERRIDE_DEFAULT_USER_AGENT='Mozilla/5.0 (Linux; Android 7.1.1; Nexus 5X Build/N4F26I) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.91 Mobile Safari/537.36'

When using with PHPUnit.

use \SMB\Screru\Traits\Testable

class Sample extends \PHPUnit_Framework_TestCase
{
    // use Trait
    use \SMB\Screru\Traits\Testable {
        setUp as protected traitSetUp;
        tearDown as protected traitTearDown;
    }

    /**
     * setUp
     */
    protected function setUp()
    {
        $this->traitSetUp();
    }

    /**
     * tearDown
     */
    protected function tearDown()
    {
        $this->traitTearDown();
    }

    // do someting ...
}

If you want to capture when an assertion fails.

takeCaptureWhenAssertionFails = true;

class Sample extends \PHPUnit_Framework_TestCase
{
    // use Trait
    use \SMB\Screru\Traits\Testable {
        setUp as protected traitSetUp;
        tearDown as protected traitTearDown;
    }

    // Set this property to true
    protected $takeCaptureWhenAssertionFails = true;

    /**
     * setUp
     */
    protected function setUp()
    {
        $this->traitSetUp();
    }

    /**
     * tearDown
     */
    protected function tearDown()
    {
        $this->traitTearDown();
    }

    // do someting ...
}

or call the function below.

$this->enableCaptureWhenAssertionFails();

// To disable, call the following function
$this->disableCaptureWhenAssertionFails();

Headless Chrome

Edit .env

// true to start headless chrome
ENABLED_CHROME_HEADLESS=true

Headless Firefox

For the latest firefox, you can use headless mode.

Edit .env

// true to start headless firefox
ENABLED_FIREFOX_HEADLESS=true
