Thanks to fab's comment. I made the following change and got it working,
$file = $this->getMockBuilder('Symfony\Component\HttpFoundation\File\UploadedFile')
->disableOriginalConstructor()
->getMock();
Question
Say I have the following class:
class Document
{
private file;
public function setFile(UploadedFile $file)
{
$this->file = $file;
}
public function getExt()
{
return $this->file->guessExtension();
}
}
I'd like to test the getExt() method. I tried to set up the test as follows:
$file = $this->getMock('UploadedFile');
$file->expects($this->at(0))
->method('guessExtension')
->will($this->returnValue('png'));
$doc = new Document();
$doc->setFile($file);
...
However, it is giving me error saying that setFile() is expecting an instance of UploadedFile and the mock object is found instead. Can anyone shed some light on how to test this kind of scenario? I am a beginner when it comes to testing with mocks and stubs.
Thanks!

OTHER TIPS
As of PHP 5.5.16 Chieh solution can't be used anymore. See reference.
A possibile solution is creating a temporary dummy file in /tmp
with setUp()/tearDown()
and pass it tot he constructor. Then we mocked the required methods to return what needed.
Note: UploadedFile
will require you to pass two parameters
