class ChanTest extends PHPUnit_Framework_TestCase
{
    protected $db;

    protected function setUp()
    {
        $this->db = new Core\Database('unitest');
    }

    /**
     * @dataProvider testProvider
     */
    public function testData($a,$b,$c)
    {
        $this->assertEquals($a + $b,$c);
    }

    public function testProvider()
    {
        $this->db->query('SELECT `a`,`b`,`c` FROM `units`');

        return $this->db->rows();
    }
}

连接到数据库本身工作

class ChanTest extends PHPUnit_Framework_TestCase
{
    protected $db;

    protected function setUp()
    {
        $this->db = new Core\Database('unitest');
    }

    public function testData($a,$c)
    {
        $this->db->query('SELECT `a`,`c` FROM `units`');

        foreach ($this->db->rows() as $item) {
            $this->assertEquals($item['a'] + $item['b'],$item['c']);
        }
    }
}

如果我通过dataProvider通过setUp函数连接数据库,它会响应致命错误：调用成员函数query(),但如果连接到数据库本身有效,dataProvider可以获取setUp函数的设置吗？
