How did you install PHPUnit? Looks like an issue with files from an older version being included.

[faridmovsumov]

I upgraded my php version from 5.3 to 5.5 maybe it is source of problem

[whatthejeff]

This shouldn't be a problem as PHPUnit is tested against 5.5. How did you install PHPUnit?

[faridmovsumov]

I installed phpunit with apt-get install phpunit command

[faridmovsumov]

This problem occured when I work in vagrant

[whatthejeff]

Which version of linux are you running?

[faridmovsumov]

My linux version is 12.04

[sebastianbergmann]

We cannot offer support for distribution-packaged versions of PHPUnit.

[whatthejeff]

Seems like an outdated version of PHPUnit. Does this solve your problem http://zechim.com/blog/2012/05/16/install-phpunit-on-ubuntu/?

[whatthejeff]

Alright, going to close this since @sebastianbergmann says we cannot support distribution-packed versions of PHPUnit. Unfortunately, many of these packages are either broken or very dated.

If the link I sent you doesn't work, I'd recommend downloading the phar or using composer to install PHPUnit.

I am having this same issue currently on Ubuntu 13.04 with PHP 5.4.9 running in Vagrant using packages from apt-get

[sebastianbergmann]

Follow the instructions on http://phpunit.de/getting-started.html

[tomtom87]

Thanks Sebastian, I have followed those instructions for the phar and I still remain with this error below:

$ phpunit
PHP Fatal error: Uncaught exception 'Exception' with message 'Unknown class name PHPUnit_TextUI_Command. Not found at /var/www/lib/PHPUnit/TextUI/Command.php' in /home/vagrant/web/site/lib/Object.php:106

[sebastianbergmann]

I assume that phpunit invokes the binary installed by your system package.

[tomtom87]

How can I ensure that it invokes the other one, where is that getting installed and how can I remove the default system package..

[tomtom87]

It was a issue with a existing framework causing this, everything fixed. thanks very much for your help sebastian :)
