Я пытаюсь выполнить тестирование моей службы, содержащей зависимый компонент Finder symfony2 (http://symfony.com/doc/current/components/finder.html).phpunit должен быть обходным или реализовать интерфейс Iterator
Я получаю:
[Exception] Объекты, возвращаемый Mock_Finder_91776c5c :: getIterator() должна быть проходимой или реализовать итератор
Услуга:
public function getFile($fileName, $path = '/')
{
if($this->wrapper == null || $this->connection == null)
throw new LogicException("call method setFTP first");
// get file on ftp server
$this->connection->open();
$downloadComplete = $this->wrapper->get($this->tmpDir . $fileName, $path . $fileName);
$this->connection->close();
if($downloadComplete == false)
return false; // TODO exception ?
// return file downloaded
$this->finder->files()->in(__DIR__);
foreach ($this->finder as $file) {
return $file;
}
return false; // TODO exception ?
}
И тест
