PHPUnit TeaDownAfterClass 使用 ZendStudio 调用得太快

Question

我在 Zend Studio 中的 PHPUnit 遇到了一个非常奇怪的问题。我有一个使用两种当前测试方法的单元测试。我使用setUpBeforeClass() 和tearDownAfterClass() 来初始化数据库连接并销毁它。我遇到的问题是在第一个测试方法之后调用tearDownAfterClass()。之后调用 setUp() 时，由于不存在数据库连接，因此会出现错误。我一辈子都搞不清楚到底发生了什么。我已经通过使用 ZendDebugger 逐步完成测试来确认该问题。我还使用 ZendStudio 中嵌入的 PHPUnit 版本。这是测试代码：

    <?php
require_once '../Code\includes\classes\datamapper\basedatamapper.class.php';
require_once '../Code\includes\classes\datamapper\userdatamapper.php';
require_once '../Code\includes\classes\users\user.class.php';
require_once 'PHPUnit\Framework\TestCase.php';

use DataMapper\UserDataMapper, Users\User;

/**
 * UserDataMapper test case.
 */
class UserDataMapperTest extends PHPUnit_Framework_TestCase {
    /**
     * @var UserDataMapper
     */
    private $UserDataMapper;

    protected static $db;

    static public function setUpBeforeClass() {
        self::$db = new PDO('mysql:host=localhost;dbname=cfoundtest', 'root', 'Andrea30Cook');
        self::$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    }
    /**
     * Prepares the environment before running a test.
     */
    protected function setUp() {
        parent::setUp();
        $this->UserDataMapper = new UserDataMapper(self::$db, simplexml_load_file(dirname(__DIR__) . '/Code/mapping/userMapping.xml')); 
    }   
    /**
     * @dataProvider UserGenerator
     */
    public function testSaveNewUser($firstname, $lastname, $password, $username, $userType, $email) {
        $user = new User();
        $user->setFirstname($firstname)
                ->setLastname($lastname)
                ->setPassword($password)
                ->setUsername($username)
                ->setUserType($userType)
                ->setEmail($email);
        $this->assertTrue($this->UserDataMapper->save($user));
        $this->assertType('int', $user->getId());
        $this->assertType('string', $user->getConfString());
        $this->assertSame(40, strlen($user->getConfString()));
    }
    /**
     * @dataProvider UserGenerator
     */
    public function testAddingUserException($firstname, $lastname, $password, $username, $userType, $email) {
        $user = new User();
        $user->setFirstname($firstname)
                ->setLastname($lastname)
                ->setPassword($password)
                ->setUsername($username)
                ->setUserType($userType)
                ->setEmail($email);
        $this->setExpectedException('InvalidArgumentException', sprintf('Username "%s" is already taken in DataMapper\UserDataMapper::insert', $user->getUsername()));
        $this->UserDataMapper->save($user);
    }

    public static function UserGenerator() {
        return array(
            array(
                'Foo',
                'Bar',
                'Secret Test',
                'Foobar',
                'Authorizer',
                '[email protected]'
            ),
            array(
                'Fred',
                'Flintstone',
                'Secret Test',
                'BarBaz',
                'Admin',
                '[email protected]'
            )
        );
    }
    /**
     * Cleans up the environment after running a test.
     */
    protected function tearDown() {
        // TODO Auto-generated UserDataMapperTest::tearDown()


        $this->UserDataMapper = null;

        parent::tearDown();
    }

    static public function tearDownAfterClass() {
        self::$db->exec('DELETE FROM failedlogins');
        self::$db->exec('DELETE FROM users');
        self::$db = NULL;
    }
}

好的，我认为这是 ZendStudio 或与其捆绑的 PHPUnit 版本的问题。该测试通过 PEAR 在命令行上安装的 PHPUnit 3.5 运行良好。我已将测试重构为测试数据中的硬代码，而不是使用数据提供程序（我知道，一点也不理想），这暂时解决了问题。
