How to assert paginations in Laravel?

I have a category model with the following method:

public static function index()
{
    return self::has('posts')->paginate(1);
}

My category controller:

public function index()
{
    $categories = Category::index();
    return view('categories.index', compact('categories'));
}

This is what I've tried:

$response = $this->get(route('categories.index'));
$response->assertViewHas('categories', Category::index());

This test fails for some reason:

Failed asserting that two objects are equal.

at tests/Feature/CategoryTest.php:38
    37|         $response->assertViewIs('categories.index');
  > 38|         $response->assertViewHas('categories', Category::index());

I would create 2 categories, and then just make sure that you can only see the first one (because the pagination):

$category1 = factory(Category::class)->create();

$category2 = factory(Category::class)->create();

$response = $this->get(route('categories.index'));

$response
	->assertSee($category1->name)
        ->assertDontSee($category2->name);

Just updated the example with categories.
