php - How to test file upload with laravel and phpunit? -

i'm trying run functional test on laravel controller. test image processing, want fake image uploading. how do this? found few examples online none seem work me. here's have:

public function testresizemethod() {     $this->preparecleandb();      $this->_createaccessablecompany();      $local_file = __dir__ . '/test-files/large-avatar.jpg';      $uploadedfile = new symfony\component\httpfoundation\file\uploadedfile(         $local_file,         'large-avatar.jpg',         'image/jpeg',         null,         null,         true     );       $values =  array(         'company_id' => $this->company->id     );      $response = $this->action(         'post',         'filestoragecontroller@store',         $values,         ['file' => $uploadedfile]     );      $readable_response = $this->getreadableresponseobject($response); } 

but controller doesn't passed check:

elseif (!input::hasfile('file')) {     return response::error('no file uploaded'); } 

so somehow file isn't passed correctly. how go this?

update

based on max.lanin's suggestin, tried:

public function setup() {     // tried parent::setup() here , @ end     // parent::setup();     $local_file = __dir__ . '/test-files/large-avatar.jpg';      print($local_file);      $_files = array(         'file' => array (             'tmp_name' => $local_file,             'name' => 'large-avatar.jpg',             'type' => 'image/jpeg',             'size' => 335057,             'error' => 0,         ),         'image' => array (             'tmp_name' => $local_file,             'name' => 'large-avatar.jpg',             'type' => 'image/jpeg',             'size' => 335057,             'error' => 0,         ),     );      parent::setup(); } 

but without succes. file used exists , size correct.

docs crawlertrait.html#method_action reads:

parameters
string $method
string $action
array $wildcards
array $parameters
array $cookies
array $files
array $server
string $content

so assume correct call should be

$response = $this->action(     'post',     'filestoragecontroller@store',     [],     $values,     [],     ['file' => $uploadedfile] ); 

unless requires non-empty wildcards , cookies.

as side note, no means unit test.
