Php – How to test file upload with laravel and phpunit

laravelPHPphpunit

I'm trying to run this functional test on my laravel controller. I would like to test image processing, but to do so I want to fake image uploading. How do I do this? I found a few examples online but none seem to work for me. Here's what I 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 the controller doesn't get passed this check:

elseif (!Input::hasFile('file'))
{
    return Response::error('No file uploaded');
}

So somehow the file isn't passed correctly. How do I go about this?

For anyone else stumbling upon this question, you can nowadays do this:

    $response = $this->postJson('/product-import', [
        'file' => new \Illuminate\Http\UploadedFile(resource_path('test-files/large-avatar.jpg'), 'large-avatar.jpg', null, null, null, true),
    ]);

UPDATE

In Laravel 6 the constructor of \Illuminate\Http\UploadedFile Class has 5 parameters instead of 6. This is the new constructor:

    /**
     * @param string      $path         The full temporary path to the file
     * @param string      $originalName The original file name of the uploaded file
     * @param string|null $mimeType     The type of the file as provided by PHP; null defaults to application/octet-stream
     * @param int|null    $error        The error constant of the upload (one of PHP's UPLOAD_ERR_XXX constants); null defaults to UPLOAD_ERR_OK
     * @param bool        $test         Whether the test mode is active
     *                                  Local files are used in test mode hence the code should not enforce HTTP uploads
     *
     * @throws FileException         If file_uploads is disabled
     * @throws FileNotFoundException If the file does not exist
     */
    public function __construct(string $path, string $originalName, string $mimeType = null, int $error = null, $test = false)
    {
        // ...
    }

So the above solution becomes simply:

$response = $this->postJson('/product-import', [
        'file' => new \Illuminate\Http\UploadedFile(resource_path('test-files/large-avatar.jpg'), 'large-avatar.jpg', null, null, true),
    ]);

It works for me.
