I am going to assume, that you did not run the dump-autoload command, since you did not mentioned it. In case you do not know what this command does, click here to find out

ok done i run :

C:\serverapache\htdocs\packtest>composer dumpautoload
Generating autoload files

tried run again a phpunit:

C:\server\packtest\vendor\dvdoug\boxpacker\tests>phpunit PackerTest
.php

Fatal error: Class 'DVDoug\BoxPacker\TestBox' not found in C:\server\packtest\vendor\dvdoug\boxpacker\tests\PackerTest.php on line 517

I think running phpunit should work directly ...

edit: I made a fresh laravel 5.2 installation and run commands like you suggested soon after:

C:\server\packtest>composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
  - Installing dvdoug/boxpacker (1.5.2)
    Loading from cache

Writing lock file
Generating autoload files
> Illuminate\Foundation\ComposerScripts::postUpdate
> php artisan optimize
Generating optimized class loader

C:\server\packtest>composer dump-autoload
Generating autoload files

C:\server\packtest>

running php unit on tests folders in vendor still same error... Am I wrong on running phpunit maybe? anyway if i create a controller in my app folder and use thepackage i got same error...

addendum:

https://github.com/dvdoug/BoxPacker/issues/38

said they resolved adding: " I have got everything to work by adding one more include: require_once $_SERVER['DOCUMENT_ROOT'] . '/../composer/vendor/dvdoug/boxpacker/tests/bootstrap.php'; "

the bootstrap contains basic implementation for packer, box, item ect ect ...

if i want to follow this solution how this "translate" into laravel system? thank guys
