[RFC] Scenario plugin system

[PedroTroller]

Hi.

Just a little reflection. Why not provide a system that allow you to describe some scenarios to execute before to crawl urls.

For example :

// MyProject/centipede.php
$scenarios = new Centipede\Scenario\Collection();

$scenarios->add('customer_account', function ($browser) {
    $broswer->visit('/login');
    $broswer->fillIn('login', 'account@email.com');
    $broswer->fillIn('password', 'strong_password');
    $broswer->press('Connection');
    $broswer->visit('/account');
});

$scenarios->add('backoffice', function ($browser) {
    $broswer->visit('/admin/login');
    $broswer->fillIn('seller[uuid]', '1122334455');
    $broswer->fillIn('seller[password]', 'strong_password');
    $broswer->press('Access to dashboard');
    $broswer->visit('/admin/dashboard');
});

$scenarios->add('public', function ($browser) {
    $broswer->visit('/');
});

return $scenarios;

And then, the crawler will execute scenarios one by one and crawl urls each time.

Yes, this would be interesting approach. In this case browser must share same session with guzzle client used in centipede crawler.

It is in deed simple extension point without reinventing the wheel, I like it.

Thanks @PedroTroller!

You could use Symfony's Client and DomCrawler classes for this (even if not asynchronous).
