Manipulate Symfony 2 UploadFile object in a unit test - php

Question

I'm working on a Symfony2 project.
I created a simple TempFile class to manipulate an UploadFile. Here is my constructor :
public function __construct(UploadedFile $file, $destination, $suffix)
{
$this->file = $file;
$this->destination = $destination;
$this->fileId = sprintf('%s_%s', uniqid(), (string) $suffix);
}
And my move method
public function move()
{
$extension = $this->file->guessExtension();
if (!$extension) {
throw new \Exception(__METHOD__ . ' -> Unable to detect extension');
}
$this->tmpFileName = sprintf('%s.%s', $this->fileId, $extension);
$this->file->move($this->destination, $this->tmpFileName);
}
I try to create an UploadFile object in my test and here is what I did :
protected function setUp()
{
$this->file = tempnam(sys_get_temp_dir(), 'upload');
imagepng(imagecreatetruecolor(10, 10), $this->file);
$this->uploadedFile = new UploadedFile($this->file, "test.png");
}
public function testMoveWithAValidUploadedFile()
{
$tempFile = new TempFile($this->uploadedFile, '/tmp', 'tmp');
$tempFile->move();
// Future assertion
}
I have the following error :
Symfony\Component\HttpFoundation\File\Exception\FileException: The file "test.png" was not uploaded due to an unknown error
Any ideas ?
Thx,
Regards

From memory, Symfony2 checks if a file was uploaded as part of the request using is_uploaded_file(). This can be overridden using the test mode of the UploadedFile class. You can also define which PHP upload error code constitutes success.
copy(__DIR__ . '/Fixtures/test.pdf', '/tmp/test.pdf');
new UploadedFile(
'/tmp/test.pdf',
'original.pdf',
null,
null,
UPLOAD_ERR_OK,
true /* test */
)
