Testing Image upload and crop/move

Hi, im trying to test image uploading and cropping after upload. Manual testing everything is fine.

I get this error Intervention\Image\Exception\NotReadableException' with message 'Unable to read image from file (/Users/ho/.....

My test

    /** @test */
    public function a_user_can_create_a_new_category()
    {
        $user = factory(App\User::class)->create();
        $this->actingAs($user)
             ->visit('admin/categories/create')
             ->type('Category Name','name')
             ->attach('storage/dummy/image.jpg','photo')
             ->press('submit__category')
             ->seePageIs('admin/categories');

         $this->seeInDatabase('categories', ['name' => 'Category Name','slug' => 'category-name']);
    }

My store function

    public function store(Request $request)
    {
        $destination = 'uploads/categories/';
        $file = $request->file('photo');
        $fileName = $file->getClientOriginalName();
        $extension = $file->getClientOriginalExtension();

        $name = md5( $fileName . time() ) . '.' . $extension;
        Image::make($file)->fit(200, 200)->save($destination . $name);

        $category = Category::create($request->all());

        $category->update(['photo' => $destination . $name]);
        return redirect('admin/categories');
    }

Result/error when running my test

1) CategoriesTest::a_user_can_create_a_new_category
A request to [http://localhost/admin/categories] failed. Received status code [500].
