Testing

You may use fake method to simulate responses from Telegram API instead of sending real requests:

use Tests\Lib\AskNameHandler;
use Tests\Lib\PopupHandler;
use WeStacks\TeleBot\Foundation\TeleBotResponse;
use WeStacks\TeleBot\Objects;
use WeStacks\TeleBot\TeleBot;

$bot->fake([

            'id' => 1,
            'type' => 'private',
        ],
        'text' => 'Please enter your name.',
    ])),
