Hånende PDO med phpunit

Du behøver ikke at håne PDO. Her er et eksempel på, hvordan det virker:

ConnectionTest.php:

<?php

class ConnectionTest extends PHPUnit_Extensions_Database_TestCase
{
    public function getConnection()
    {
        $database = 'myguestbook';
        $user = 'root';
        $password = '';
        $pdo = new PDO('mysql:host=localhost;dbname=myguestbook', $user, $password);
        $pdo->exec('CREATE TABLE IF NOT EXISTS guestbook (id int, content text, user text, created text)');
        return $this->createDefaultDBConnection($pdo, $database);
    }

    public function getDataSet()
    {
        return $this->createFlatXMLDataSet(__DIR__.'/dataSets/myFlatXmlFixture.xml');
    }

    public function testGetRowCount()
    {
        $this->assertEquals(2, $this->getConnection()->getRowCount('guestbook'));
    }
}

myFlatXmlFixture.xml

<?xml version="1.0" ?>
<dataset>
    <guestbook id="1" content="Hello buddy!" user="joe" created="2010-04-24 17:15:23" />
    <guestbook id="2" content="I like it!" user="nancy" created="2010-04-26 12:14:20" />
</dataset>

Resultat:

PHPUnit 4.7.6 by Sebastian Bergmann and contributors.

OK (1 test, 1 assertion)

Hovedpointen i test mod db er ikke at håne db, men også skabe absolut samme PDO-forbindelse ikke til produktions-db, men til db for test, det kan være mysql, sqlite osv...
