I'm working with Selenium and Laravel 5.1

I am testing with Selenium with the great Jeffrey way's extension Integrated, but it seems to do basic stuff, but it doesn't do evertything Selenium does.

My problem is I can't find very well a way to extend it, I don't really get it how does it work. Most of selenium docs are in JS, and I need PHP.

When I open file Selenium.php in Integrated package, I don't really see what is the bridge between PHP and Selenium.

My main issue right now is I must deal with autocomplete field.

So, user should enter a CP number, wait 2 sec, and clic an autocomplete list ( < li >item< /li > )

I saw a lot of docs about selenium + autocomplete fields, but I don't actually understand how to apply it to Laravel and to integrated..

Any idea that can help???
