The AbstractFile class has the method checkIsUploadedFile. However if I want to mock/fake an uploaded file for in example unit testing, I have implement/override all these classes, since they all extend from it:

• Phalcon\Filter\Validation\Validator\File\Resolution\Min
• Phalcon\Filter\Validation\Validator\File\Resolution\Max
• Phalcon\Filter\Validation\Validator\File\Resolution\Equal
• Phalcon\Filter\Validation\Validator\File\Size\Min
• Phalcon\Filter\Validation\Validator\File\Size\Max
• Phalcon\Filter\Validation\Validator\File\Size\Equal
• Phalcon\Filter\Validation\Validator\File\MimeType
• Phalcon\Filter\Validation\Validator\File

Would be much easier if an option would be implemented like:

    protected function checkIsUploadedFile(string name) -> bool
    {
         if ($this->getOption('ignoreCheckUploadedFile')) {
            return true;
        }

        return is_uploaded_file(name);
    }

As an addition, it would also be nice if this validator accepted the Phalcon native $this->request->getUploadedFiles() instead of the PHP's $_FILES.
