How to use phpunit with php4 code - php

Question

I have the following example test code (PHP4) I need to run with phpunit:
<?php
require_once 'PHPUnit/Framework.php';
class RemoteConnectTest extends PHPUnit_Framework_TestCase
{
public function setUp(){ }
public function tearDown(){ }
public function testConnectionIsValid()
{
$this->assertTrue(true);
}
}
?>
which does not run with phpunit:
PHP Fatal error: require_once(): Failed opening required 'PHPUnit/Framework.php' ...
How do I need to setup my environment to make this work (Linux, Ubuntu 12.04)? Do I need to set a search path? Change php.ini? I AM NOT ABLE TO CHANGE THE TEST CODE ITSELF.

Answer 1

The answer is an incompatibility between the used versions. Newer versions of phpunit do have a different internal setup (see example for 3.7 here) which are different from older phpunit versions.
One need to 'downgrade' phpunit, as example as follows:
sudo pear uninstall phpunit/PHPUnit
sudo pear install phpunit/PHPUnit-3.2.8
to install version 3.2.8, for example. It can be verified the existance of the file Framework.php:
> ls /usr/share/php/PHPUnit
Extensions Framework Framework.php Runner TextUI Util
The example code should work now when called as
phpunit SimpleTest.php
(assuming identical name of class and file [excluding the php of course]).

Answer 2

Since you can run phpunit from command line, you most likely have the source code installed with PEAR already (or composer, which is less likely). But path to framework is not in global include paths (or in system variable PATH).
The path to PHPUnit is usually inside PEAR. And PEAR is usually near php installation. You can always use global filesearch in terminal with
find / -name 'Framework.php' 2>/dev/null
You either need to either
edit php.ini and add path to PHPUnit in include_path directive
require_once absolute path
use autoloading (but thats only from PHP 5.3)
