Something like this ```php set_error_handler(function ($errno, $errstr) { // $errstr can be "exec() has been disabled for security reasons" if disable_functions=exec ini exists }, E_WARNING); $vendorDir = exec('composer config vendor-dir');...

So, am I have to create pull request without error handler?

uuf as I see there is no way to write test - vendor autoloader paths hardcoded inside e2etest runner

@maks-rafalko I don't fully understand what should I do to complete this pr.
