我正在尝试对我的服务进行单元测试,其中包含symfony2(http://symfony.com/doc/current/components/finder.html)的依赖项查找器组件。
我得到了:
Mock_Finder_91776c5c::getIterator()返回的
异常对象必须是可遍历的或实现接口迭代器
服务:
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 ?
}
和测试
class FtpServiceTest extends \PHPUnit_Framework_TestCase
{
protected $connectionMock;
protected $ftpWrapperMock;
protected $finderMock;
protected function setUp()
{
$this->connectionMock = $this->getConnectionMock();
$this->ftpWrapperMock = $this->getFTPWrapperMock();
$this->finderMock = $this->getFinderMock();
}
protected function tearDown()
{
}
private function getFinderMock()
{
return $this->getMockBuilder(Finder::class)
->disableOriginalConstructor()
->getMock('Iterator');
}
private function getConnectionMock()
{
return $this->getMockBuilder(Connection::class)
->disableOriginalConstructor()
->getMock();
}
private function getFTPWrapperMock()
{
return $this->getMockBuilder(FTPWrapper::class)
->disableOriginalConstructor()
->getMock();
}
// tests
public function testMe()
{
// arrange
$host = 'localhost';
$user = 'user';
$password = '1234';
$filesArray = new ArrayObject(array(''));
$service = new FtpService('var/tmp/');
$service->setFTP($this->connectionMock, $this->ftpWrapperMock);
$service->setFinder($this->finderMock);
$this->connectionMock
->expects($this->once())
->method('open');
$this->ftpWrapperMock
->expects($this->once())
->method('get')
->will($this->returnValue(true));
$this->connectionMock
->expects($this->once())
->method('close');
$this->finderMock
->expects($this->once())
->method('files')
->will($this->returnValue($this->finderMock));
$this->finderMock
->expects($this->once())
->method('in')
->will($this->returnValue($filesArray));
// act
$file = $service->getFile('/file.zip');
// assert
$this->assertInstanceOf(SplFileInfo::class, $file);
}
}

Finder
类的模拟实例需要实现/模拟方法getIterator
。getMock
方法不接受参数,因此不要传递字符串'Iterator'
-change代码,如下所示:
private function getFinderMock()
{
return $this->getMockBuilder(Finder::class)
->disableOriginalConstructor()
->getMock();
}
并在测试方法中添加模拟期望,例如:
$this->finderMock->expects($this->once())
->method('getIterator')
->willReturn(new \ArrayObject([$this->createMock(SplFileInfo::class)]));
希望这能有所帮助。
