Class __PHP_Incomplete_Class has no unserializer

Question

I am trying to run the tests in PHPUnit and getting this error.

Fatal error: Uncaught exception 'ErrorException' with message 'Class __PHP_Incomplete_Class has no unserializer' in /opt/lampp/lib/php/PHPUnit/Util/PHP.php:237

PHP - 5.4.7
PHPUnit - 3.7.21

PHPUnit setting :

processIsolation = "true"

Have you tried googling this? google.co.uk/… Seems to be an issue specific to PHPUnit and symfony2 – Rillings

https://mcmap.net/q/829525/-unserialize-error-when-runinseparateprocess might be related. When working with a framework that put a PDO connection in its global scope, the solution was to add that variable to the backupglobalblacklist: phpunit.de/manual/3.7/en/fixtures.html#idp7165424 – Papistry

Answer 1

Try clearing the cache for the test environment. php app/console cache:clear --env=test

Thanks, but it did not work, I know the reason but i am not sure about it since i do not have any solution to it. This problem is due do the "GLOBALS" handling differently in PHP and PHPUNIT, i have even tried out this option(phpunit.de/manual/3.7/en/…) – Marabelle

Answer 2

Here's a debugging solution that might help you finding where the unserialize method is failing:

<?php
ini_set('unserialize_callback_func', 'debug_unserialize');

function debug_unserialize($classname) 
{
    die(var_dump($classname));
}

That way you will see which classname is causing problem.

Useful command. However, my output shows a class that does not exist. Any ideas on why that would be? I have a feeling it is due to something gone wrong with composer or the cache, but I have cleared both and re-installed composer packages – Weissman

Answer 3

Try opening your site in a browser and then again try to execute the test. I am sure it would work, it seems that there is some difference in cache generation by Php Unit and by Symfony

Updating symfony to symfony 3.3.18 works for me!
