Getting PHPUnit Working - Include Path not set correctly?

Question

I'm trying to get PHPUnit working on my development environment but I've hit a bit of a roadblock when it comes to including PHPUnit in my scripts. I know that I need to set the include path on PHP but every combination I've tried fails without the compiler seeing the PHPUnit_Framework_TestCase class.

I just ran updates on PHP and PEAR and PHPUnit is installed on the computer because I can access it through the command line just fine.

PHPUnit is installed at /usr/share/php/PHPunit

Pear is at /usr/share/php/PEAR

Is there something I'm missing? This is my first time trying to use PHPUnit or even something from PEAR for that matter. I'm on Ubuntu 10.10. Any help would be appreciated.

Edit - There is nothing in the include path in my PHP ini. Right now the code is just

<?php
class Stacktest extends PHPUnit_Framework_TestCase
{

}

I have no idea what to include or what to set in the include path because it seems that for all the info on the web about PHPUnit, this little bit of information is critically absent.

Answer 1

As of PHPUnit 3.5, you have to include the autoloader yourself:

require 'PHPUnit/Autoload.php'; // PEAR should be in your include_path

Answer 2

If you installed phpunit correctly (through PEAR), then there is no need for an include file; you just need to change the way you use it to test php files (e.g. you use it to test if the file worked by going to the browser type localhost). With phpunit you can use the command line; chapter 5 gives the same example using the command line (I would assume it's a standard). So if you got it installed correctly you can do this:

1. File ExampleTest.php, located at the root of localhost (for me this is /var/www):

   class ExampleTest extends PHPUnit_Framework_TestCase
   {
       public function testOne()
       {
           $this->assertTrue(FALSE);
       }
   }
   

2. Open a console (terminal on Mac or Linux, command prompt on Win), navigate to your localhost document root (where you saved ExampleTest.php) and type the following:

   phpunit --verbose ExampleTest.php
   

3. You should see:

   PHPUnit 3.4.13 by Sebastian Bergmann.
   
   F
   
   Time: 1 second, Memory: 6.50Mb
   
   There was 1 failure:
   
   1) ExampleTest::testOne
   Failed asserting that <boolean:false> is true.
   
   /var/www/ExampleTest.php:6
   
   FAILURES!
   Tests: 1, Assertions: 1, Failures: 1.
   

Notes: All the above assumes you installed phpunit correctly (as stated in chapter 3) and you restarted apache after that .

if you really want to run tests in your browser use the following code

# error reporting
ini_set('display_errors',1);
error_reporting(E_ALL|E_STRICT);

# include TestRunner
require_once 'PHPUnit/TextUI/TestRunner.php';

# our test class
class ExampleTest extends PHPUnit_Framework_TestCase
{
    public function testOne()
    {
        $this->assertTrue(FALSE);
    }
}

# run the test
$suite = new PHPUnit_Framework_TestSuite('ExampleTest');
PHPUnit_TextUI_TestRunner::run($suite);

Edit

Just spotted Ubuntu 10.10 in your question. For Ubuntu install I recommend this: in terminal do:

sudo pear uninstall phpunit/PHPUnit
sudo apt-get install phpunit
sudo /etc/init.d/apache2 restart

Note: Don't issue the first line if you didn't install phpunit through pear. The last line seems to be needed (in my case at least).

sudo /etc/init.d/apache2 reload # Or
sudo service apache2 restart

Answer 3

Add this line to your php.ini :

include_path=".:/usr/share/php:/usr/share/pear:/usr/share/php/PHPunit:/usr/share/php/PEAR"

Save the file and restart apache.

Also, make sure you editing the correct php.ini. Try using locate php.ini to find all the places it might be hiding. It's usually under the /usr directory somewhere.

Answer 4

Make sure every time to use include() or require(), you prefix the actual file name with dirname(__FILE__). This ensures that the file you are including is at the path you specify relative to the actual file that the include is in. By deftault, PHP includes relative to the file that is invoked to start the program.
