unable to attach test reporter

Hallo

I am using PhpStorm Version 2.1.2 Build #PS-107.425 with Windows7. My local server is a XAMPP version 1.7.4 and I reinstalled an updated version of PHPUnit 3.5.14.

Now I am trying to run a phpunit example:

require_once 'PHPUnit2/Framework/TestCase.php';

class ArrayTest extends PHPUnit2_Framework_TestCase {

    protected function setUp() {
        parent::setUp();
    }

    protected function tearDown() {
        parent::tearDown();
    }

    public function testNewArrayIsEmpty()
    {
        // Create the Array fixture.
        $fixture = array();

        // Assert that the size of the Array fixture is 0.
        $this->assertEquals(0, sizeof($fixture));
    }

    public function testArrayContainsAnElement()
    {
        // Create the Array fixture.
        $fixture = array();

        // Add an element to the Array fixture.
        $fixture[] = 'Element';

        // Assert that the size of the Array fixture is 1.
        $this->assertEquals(1, sizeof($fixture));
    }
}

The test is running and I got the messages in the right window, but in the left there is only one error message 'Unable to attach test reporter to test framework'. There should be a list of the test methods, or not?
