Zend Framework 2 数据库测试 - 非对象上的 canCallMagicCall()

Question

我一直在尝试使用本教程测试我的模型表：http://framework.zend.com/manual/2.1/en/tutorials/unittesting.html

我尝试将它们应用到我自己的应用程序中，实际上它与教程中的专辑非常相似，只是做了一些小修改。

当我尝试运行 fetchAll() 测试时，我收到以下错误：

PHP Fatal error:  Call to a member function canCallMagicCall() on a non-object in C:\Program Files (x86)\Zend\Apache2\htdocs\ukazka2\vendor\zendframework\zendframework\library\Zend\Db\TableGateway\AbstractTableGateway.php on line 470

我的测试代码如下：

public function testFetchAllReturnsAllBooks(){
    $resultSet = new ResultSet();
    $mockTableGateway = $this->getMock('Zend\Db\TableGateway\TableGateway',
            array('select'), array(), '', false);
    $mockTableGateway->expect($this->once())
                     ->method('select')
                     ->with()
                     ->will($this->returnValue($resultSet));

    $bookTable = new BookTable($mockTableGateway);

    $this->assertSame($resultSet, $bookTable->fetchAll());
}

这是我的 fetchAll() 函数：

public function fetchAll(){
    if(($resultSet = $this->cache->getItem('books')) == FALSE){
        $resultSet = $this->tableGateway->select();
        $resultSet = $resultSet->toArray();
        $this->cache->setItem('books', $resultSet);         
    }
    $books = array();
    $hydrator = new Hydrator\ArraySerializable();
    foreach($resultSet as $result){
        $books[] = $hydrator->hydrate($result, new Book());
    }
    return $books;
}

你有什么提示可能存在错误吗？

Answer 1

你确定你调用的方法是正确的就行了：

$mockTableGateway->expect($this->once())

据我在 Zend 文档中看到的，它应该是 expects()。如果是这种情况，请尝试让我知道。
