单元测试 上传文件.php 在 PHPSpec 中

Question

我正在尝试测试一个数据传输对象类，该类在 Laravel 中构造SymfonyComponentHttpFoundationFileUploadedFile.php类。我没有运气在PHPSpec中测试此实现。这是我到目前为止所拥有的：

测试

public function let($event_id)
{
    $prophet = new Prophet;
    $prophecy = $prophet->prophesize();
    $prophecy->willBeConstructedWith(array('path', 'name'));
    $prophecy->willExtend('SymfonyComponentHttpFoundationFileUploadedFile');
    $attendee_list = $prophecy->reveal();
    $this->beConstructedWith($event_id, $attendee_list);
}
public function it_is_initializable()
{
    $this->shouldHaveType('CaptixAttendeesImportAttendeesCommand');
}

类

class ImportAttendeesCommand
{
/**
 * Event primary key
 * @var $event_id
 */
protected $event_id;
/**
 * CSV file
 * @var $attendee_list
 */
protected $attendee_list;
/**
 * Constructor for ImportAttendeesCommand
 */
public function __construct($event_id, UploadedFile $attendee_list)
{
    $this->event_id = $event_id;
    $this->attendee_list = $attendee_list;
}
}

结果

我已经尝试了几种方法来测试这一点，使用Mockery，Prohpecy，stdClass，似乎没有任何效果。对此的任何帮助将不胜感激。我欢迎此测试的任何实施。提前感谢大家。

Answer 1

创建一个接口：

interface UploadedFileInterface
{}

创建实现此接口并扩展 Symfony 类的类。

class MyUploadedFile extends UploadedFile implements UploadedFileInterface
{}

更改命令中的构造函数：

public function __construct($event_id, UploadedFileInterface $attendee_list)
{
    $this->event_id = $event_id;
    $this->attendee_list = $attendee_list;
}

现在，您可以轻松地单独测试您的类：

public function let($event_id, UploadedFileInterface $attendeeList)
{
    $this->beConstructedWith($event_id, $attendeeList);
}

如果有一天你将不得不从Symfonys UploadedFile切换到另一个实现，你唯一需要改变的地方将是MyUploadedFile类。

我在使用预言来模拟上传文件时遇到了同样的问题，所以我提交了一个问题以供反馈 （https://github.com/phpspec/prophecy/issues/184）。

解决方案是"不要嘲笑你不拥有的东西"。我还不确定您将如何将其付诸实践，但我想您可能会感兴趣。
