Test an upload with PHPUnit in Laravel - php

Question

Currently, i try to test a file upload with PHPUnit for Laravel. After some searches, i found a first solution :
$file = new \Symfony\Component\HttpFoundation\File\UploadedFile(
app_path() . '/tests/Files/default.png', 'default.png');
$response = $this->call('POST', 'students',
[
'firstname' => 'firstname',
'lastname' => 'lastname',
'promotion' => '2016',
'isCoop' => 1
],
[
'avatar' => [$file]
]
);
It works, but it failed when I push this code on Travis, and i'm not sure it's very clean to do that...
You can see my test failed here.
Thank's you.

Answer 1

You should use virtual file system for your tests. Check mocking file system in the phpunit documentation

Answer 2

You can use this class \Illuminate\Http\UploadedFile to test your upload file as you can see on this answer
mine working using test case like this :
public function testUploadLanscapseValid()
{
$uploadFile= new \Illuminate\Http\UploadedFile(
base_path()."/resources/fakerFile/mobileScreen/bg_land.jpg", //path image
'example.jpg',
'image/jpeg',
filesize(base_path()."/resources/fakerFile/mobileScreen/bg_land.jpg"), // file size
null,
true
);
//checking UI validation response
$this->visit('/mobile-screen')
->attach($uploadFile, 'image-landscape')
->press('upload-image-landscapse')
->seePageIs('/mobile-screen')
->see('Mobile screen successfully uploaded.');
//checking database is inserted
$this->seeInDatabase('mobile_screen',['link_lanscapse'=>'bg_land.jpg']);
//checking file exist
if(file_exists(base_path() . '/public/mobileScreen/bg_land.jpg')){
$this->assertTrue(true);
}else{
$this->assertTrue(false);
}
}
when you are testing upload using file please use \Illuminate\Http\UploadedFile instead of \Symfony\Component\HttpFoundation\File\UploadedFile
UPDATE
when seeing your test I think it is incomplete you can get the response of your test like mine here :
public function testUploadFunctionalTest()
{
$uploadedFile= new \Illuminate\Http\UploadedFile(
base_path()."/resources/fakerFile/mobileScreen/bg_land.jpg", //path image
'example.jpg',
'image/jpeg',
filesize(base_path()."/resources/fakerFile/mobileScreen/bg_land.jpg"), // file size
null,
true
);
// you can use this or
$parameters = [];
$response = $this->action(
'POST',
'AdminWeb\MobileScreenController#store',
[],
$parameters,
[],
['image' => $uploadedFile]
);
// you can use this choose One !
$response =$this->call('POST', 'mobile-screen#store',
[
'firstname' => 'firstname',
'lastname' => 'lastname',
'promotion' => '2016',
'isCoop' => 1
],
[
'image' => [$uploadedFile]
]);
$result = json_decode($response->content()); // you can dump or whatever you want with the test
var_dump($result->your_response);
$this->assertEquals($result->your_response,'expected output');
}
Note : I'm using laravel 5.2, and this test will write the file on your disk

Answer 3

$file = new \Symfony\Component\HttpFoundation\File\UploadedFile(
app_path() . '/tests/Files/default.png', 'default.png', "image/jpeg", null, null, true);
