Laravel shared hosting , setup test environment

I am using shared hosting to host my website. I would like to setup a test environment. I am currently on Laravel 5 and my website works fine.

Any guide, I should follow to setup a test environment online ? I have added a domain "test.domain.com"

added this folder in public_html The content of index file is

require __DIR__.'/./domain.dev1/bootstrap/autoload.php';

$app = require_once __DIR__.'/./domain.dev1/bootstrap/app.php';


$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);

$response = $kernel->handle(
    $request = Illuminate\Http\Request::capture()
);

$response->send();

$kernel->terminate($request, $response);

But when i try to open the website "test.domain.com" I get the following error in error_log

[22-Sep-2016 09:13:12 Etc/GMT] PHP Warning:  require(/home/exelrqma/public_html/http://ift.tt/2cJ4xUT): failed to open stream: No such file or directory in /home/exelrqma/public_html/http://ift.tt/2d6htGQ on line 22

What do I need to do to ensure test.domain.com works fine. I have also copied my project folder and added to home (same structure as my main "domain.com")
