How to test file upload in Laravel 5.2

When you create an instance of UploadedFile set the last parameter $test to true.

$file = new UploadedFile($path, $name, filesize($path), 'image/png', null, true);                                                                           ^^^^

Here is a quick example of a working test. It expects that you have a stub test.png file in tests/stubs folder.

class UploadTest extends TestCase{    public function test_upload_works()    {        $stub = __DIR__.'/stubs/test.png';        $name = str_random(8).'.png';        $path = sys_get_temp_dir().'/'.$name;        copy($stub, $path);        $file = new UploadedFile($path, $name, filesize($path), 'image/png', null, true);        $response = $this->call('POST', '/upload', [], [], ['photo' => $file], ['Accept' => 'application/json']);        $this->assertResponseOk();        $content = json_decode($response->getContent());        $this->assertObjectHasAttribute('name', $content);        $uploaded = 'uploads'.DIRECTORY_SEPARATOR.$content->name;        $this->assertFileExists(public_path($uploaded));        @unlink($uploaded);    }}

In Laravel 5.4 you can also use \Illuminate\Http\UploadedFile::fake(). A simple example below:

/** * @test */public function it_should_allow_to_upload_an_image_attachment(){    $this->post(        action('AttachmentController@store'),        ['file' => UploadedFile::fake()->image('file.png', 600, 600)]    );    /** @var \App\Attachment $attachment */    $this->assertNotNull($attachment = Attachment::query()->first());    $this->assertFileExists($attachment->path());    @unlink($attachment->path());}

If you want to fake a different file type you can use

UploadedFile::fake()->create($name, $kilobytes = 0)

I think this is the easiest way to do it

$file=UploadedFile::fake()->image('file.png', 600, 600)];$this->post(route("user.store"),["file" =>$file));$user= User::first();//check file exists in the directoryStorage::disk("local")->assertExists($user->file); 

and I think the best way to delete uploaded files in the test is by using tearDownAfterClass static method,this will delete all uploaded files

use Illuminate\Filesystem\Filesystem;public static function tearDownAfterClass():void{        $file=new Filesystem;        $file->cleanDirectory("storage/app/public/images");}
