PHPunit忽略getConnection（）和getDataSet（）

Question

abstract class App_Tests_DatabaseTestCase extends PHPUnit_Extensions_Database_TestCase {
    protected $App;

    /**
     * @return PHPUnit_Extensions_Database_DB_IDatabaseConnection
     */
    public function log($text)
    {
        $file = '/Applications/MAMP/htdocs/zumba/app/vendors/billing/tests/abstract/log.txt';

        $current = file_get_contents($file);
        $current .= $text."\n";
        file_put_contents($file, $current);
    }

    final public function getConnection()
    {
        $this->log("Initiate Get Connection");
        $this->App = new App();
        if ($this->conn === null) {
            if (self::$pdo == null) {
                self::$pdo = new PDO( $GLOBALS['DB_DSN'], $GLOBALS['DB_USER'], $GLOBALS['DB_PASSWD'] );
            }
            $this->conn = $this->createDefaultDBConnection(self::$pdo, $GLOBALS['DB_DBNAME']);
        }

        return $this->conn;
    }

    protected function getDataSet()
    {
        $this->log("Initiate GetDataSet");
        return new ZumbaDbUnitArrayDataSet(array(
            'guestbook' => array(
                array('id' => 1, 'content' => 'Hello buddy!', 'user' => 'joe', 'created' => '2010-04-24 17:15:23'),
                array('id' => 2, 'content' => 'I like it!',   'user' => null,  'created' => '2010-04-26 12:14:20'),
            ),
        ));
    }

    protected function setUp() {
        $this->log("Initiate Setup");
        $this->App = new App();
    }

    protected function tearDown() {
        $this->log("Initiate Tear Down");
        unset($this->App);
    }
}

我添加了一个日志来跟踪进度但结果相同

以下是输出

Configuration read from 

F Initiate Setup Initiate Tear Down

Time: 0 seconds, Memory: 6.25Mb

There was 1 failure:

1) BillingControlTest::test_funrun
Failed asserting that false is true.



FAILURES!
Tests: 1, Assertions: 1, Failures: 1.

我执行此文件

class BillingControlTest extends App_Tests_DatabaseTestCase {
    function test_funrun()
    {
        $returnVal = $this->App->query("UPDATE guestbook SET created = NOW() WHERE id = 1");
        $this->assertTrue($returnVal);
    } 
}

如你所见。它贯穿setup和tearDown但跳过getConnection和getDataset。我正在关注网站上的教程。
