Php – Error when running PHPUnit

PHPphpunitubuntu-11.10unit testing

I get the following error when I try to run phpunit . from within my project's tests folder:

PHP Fatal error:  Call to undefined method PHP_CodeCoverage_Filter::getInstance() in /usr/share/php/PHPUnit/Framework.php on line 46

I installed PHPUnit via these commands:

sudo pear channel-discover pear.symfony-project.com
sudo pear channel-discover components.ez.no
sudo pear install --alldeps phpunit/PHPUnit

As none of the other methods seem to work, including apt-get.

I think CodeCoverage changed their singleton pattern at some point in time and hence removed getInstance but I don't know how to fix this error. How can I either downgrade CodeCoverage or upgrade PHPUnit?

I tried manually installing the latest versions of everything via the following commands:

sudo apt-get install git
mkdir phpunit && cd phpunit
git clone git://github.com/sebastianbergmann/phpunit.git
git clone git://github.com/sebastianbergmann/dbunit.git
git clone git://github.com/sebastianbergmann/php-file-iterator.git
git clone git://github.com/sebastianbergmann/php-text-template.git
git clone git://github.com/sebastianbergmann/php-code-coverage.git
git clone git://github.com/sebastianbergmann/php-token-stream.git
git clone git://github.com/sebastianbergmann/php-timer.git
git clone git://github.com/sebastianbergmann/phpunit-mock-objects.git
git clone git://github.com/sebastianbergmann/phpunit-selenium.git
git clone git://github.com/sebastianbergmann/phpunit-story.git
git clone git://github.com/sebastianbergmann/php-invoker.git
sudo cp -r dbunit/PHPUnit /usr/share/php/
sudo cp -r php-code-coverage/PHP /usr/share/php/
sudo cp -r php-file-iterator/File /usr/share/php/
sudo cp -r php-invoker/PHP /usr/share/php/
sudo cp -r php-text-template/Text /usr/share/php/
sudo cp -r php-timer/PHP /usr/share/php/
sudo cp -r php-token-stream/PHP /usr/share/php/
sudo cp -r phpunit/PHPUnit /usr/share/php/
sudo cp -r phpunit-mock-objects/PHPUnit /usr/share/php/
sudo cp -r phpunit-selenium/PHPUnit /usr/share/php/
sudo cp -r phpunit-story/PHPUnit /usr/share/php/
sudo cp -r phpunit/phpunit.php /usr/share/php/

But that didn't help any. Now I just have a bunch of junk all over the place :\

you can try this, I have done it on my Ubuntu 12.04

sudo pear uninstall phpunit/PHPUnit
sudo pear uninstall pear.phpunit.de/PHPUnit_MockObject
sudo pear install pear.phpunit.de/PHPUnit_MockObject
sudo pear install --alldeps pear.phpunit.de/PHPUnit

I have tried many other methods. This works when I get the error blow.

Short Answer

Use $this to refer to the current object. Use self to refer to the current class. In other words, use $this->member for non-static members, use self::$member for static members.

Full Answer

Here is an example of correct usage of $this and self for non-static and static member variables:

<?php
class X {
    private $non_static_member = 1;
    private static $static_member = 2;

    function __construct() {
        echo $this->non_static_member . ' '
           . self::$static_member;
    }
}

new X();
?>

Here is an example of incorrect usage of $this and self for non-static and static member variables:

<?php
class X {
    private $non_static_member = 1;
    private static $static_member = 2;

    function __construct() {
        echo self::$non_static_member . ' '
           . $this->static_member;
    }
}

new X();
?>

Here is an example of polymorphism with $this for member functions:

<?php
class X {
    function foo() {
        echo 'X::foo()';
    }

    function bar() {
        $this->foo();
    }
}

class Y extends X {
    function foo() {
        echo 'Y::foo()';
    }
}

$x = new Y();
$x->bar();
?>

Here is an example of suppressing polymorphic behaviour by using self for member functions:

<?php
class X {
    function foo() {
        echo 'X::foo()';
    }

    function bar() {
        self::foo();
    }
}

class Y extends X {
    function foo() {
        echo 'Y::foo()';
    }
}

$x = new Y();
$x->bar();
?>

The idea is that $this->foo() calls the foo() member function of whatever is the exact type of the current object. If the object is of type X, it thus calls X::foo(). If the object is of type Y, it calls Y::foo(). But with self::foo(), X::foo() is always called.

Php – Best practices to test protected methods with PHPUnit

If you're using PHP5 (>= 5.3.2) with PHPUnit, you can test your private and protected methods by using reflection to set them to be public prior to running your tests:

protected static function getMethod($name) {
  $class = new ReflectionClass('MyClass');
  $method = $class->getMethod($name);
  $method->setAccessible(true);
  return $method;
}

public function testFoo() {
  $foo = self::getMethod('foo');
  $obj = new MyClass();
  $foo->invokeArgs($obj, array(...));
  ...
}
