PDO模拟对象缺少getConnection

Question

像这样模拟PDO对象之后:

class AdProvidersTest extends PHPUnit_Framework_TestCase
{
    public function dataProvider()
    {
        $providers =  array (
            array (1, '1st', 'desc_1', 101),
            array (2, '2nd', 'desc_2', 202),
            array (3, '3rd', 'desc_3', 303)
          );

        return $providers;
    }
    /**
     * @dataProvider dataProvider
     */
    public function testAdProviders_getConnection($id, $name, $desc, $account_id)
    {
        $data = array (
            array (
                'id' => $id,
                'name' => $name,
                'desc' => $desc,
                'account_id' => $account_id,
            )
        );

        $stmt = $this->getMock('PDOStatement', array ('execute','fetchAll'));
        $stmt->expects($this->any())
             ->method('execute')
             ->will($this->returnValue(true));
        $stmt->expects($this->any())
             ->method('fetchAll')
             ->will($this->returnValue($data));

        $pdo = $this->getMock('PDO', array('prepare'),
            array('sqlite:dbname=:memory'),'PDOMock_' . uniqid(),true);
        $pdo->expects($this->any())
            ->method('prepare')
            ->will($this->returnValue($stmt));


    }
}

我想使用此函数测试连接:

      function getDbh() 
      {
        if ($this->db === null){
          $this->db = Slim::getInstance()->db;
        }
        return $this->db->getConnection();
      }

但在使用pdo mock设置数据库后,我在尝试获取连接时遇到此错误:

PHP Fatal error:  Call to undefined method AdProvidersTest::getMockConnection() in /home/al/adserver/adserver/test/classes/AdProvidersTest.php on line 48

有没有办法将此getConnection功能添加到模拟的PDO？

Answer 1

您的错误消息指出，第 48 行正在调用中的AdProvidersTest.php方法，并且您尚未在 中定义该方法getMockConnection()class AdProvidersTest getMockConnection()class AdProvidersTest

这是否有助于您缩小答案范围？
