PHPUnit_Extensions_Database_Testcase returns undefined method - php

Question

Im getting a Fatal error: Call to undefined method PHPUnit_Extensions_Database_DB_DefaultDatabaseConnection::prepare() on a phpunit test where I'm preparing a PDO statement. If the default database connection is a copy of the pdo object that successfully connects, wouldn't it have access to its methods?
My Class and the function in question:
class User
{
protected $db;
public function __construct($db)
{
$this->db = $db;
}
public function deleteItem($itemId)
{
$sql = "
DELETE FROM Users WHERE id = ?";
$sth = $this->db->prepare($sql);//this is the failed line works on other tests
return $sth->execute(array($itemId));
}
My Test:
class RosterDBTest extends PHPUnit_Extensions_Database_Testcase
{
public function getConnection()
{
$pdo = new PDO('mysql:host=localhost;dbname=users','root','root');
return $this->createDefaultDBConnection($pdo,"users");
}
public function getDataSet()
{
return $this->createFlatXMLDataset(
dirname(__FILE__) . '/users.xml');
}
public function setup()
{
$this->db = $this->getConnection();
}
public function testRemoveUser()
{
$testUser = new User($this->db);
$expectedUsers = 123;
$testUser->deleteItem(91);
$totalUsers = $testUsers->getAllUsers();
$this->assertEquals( $expectedUsers,count($totalUsers), 'Did not delete User 91' );
}

I've just been stuck on a similar problem where I had my abstract database testcase class. Solved it by changing
public function setup()
{
$this->db = $this->getConnection();
}
to
public function setup()
{
$this->db = $this->getConnection()->getConnection();
}
Not sure if this helps with this but hopefully will help someone.
