База данных с PHPUnit -Selenium Framework

Может ли кто-нибудь предоставить мне хороший и полный источник для тестирования баз данных с помощью PHPUnit?
В настоящее время я имею в виду это
Источник

Делая так, я получил эту ошибку:

Хотя я включил файл в строку № 3.
Мой полный исходный код:

<?php
require_once "PHPUnit/Autoload.php";
require_once "ArticleDAO.php";

class ArticleDAOTest extends PHPUnit_Extensions_Database_TestCase implements IArticleDAO
{
public function getConnection() {
$db = new PDO(
"mysql:host=localhost;dbname=bulletproof",
"root", "password");
return $this->createDefaultDBConnection($db, "bulletproof");
}

public function getDataSet() {
return $this->createXMLDataSet("seed.xml");
}
public function getArticles($sectionId, $isHome) {
$db = new PDO(
"mysql:host=localhost;dbname=bulletproof",
"root", "password");

$result = $db->query("SELECT a.id, a.title FROM features f LEFT JOIN articles a ON f.article_id = a.id AND f.section_id = 1");
$articles = array();
while ($row = $result->fetch(PDO::FETCH_ASSOC)) {
$articles[] = $row;
}
$result->closeCursor();

return $articles;
}
public function testGetArticlesNonHome() {
$articleDAO = new ArticleDAO();
$articles = $articleDAO->getArticles(1, false);
$this->assertEquals(
array(
array("id" => 1, "title" => "Android vs iOS"),
array("id" => 2, "title" => "Android vs Wp7"),
array("id" => 3, "title" => "iOS 5")),
$articles);
}
}

Мой файл ArticleDAO.php

<?php
interface IArticleDAO
{
public function getArticles($sectionId, $isHome);
}
