<?php

// add this macro to your service provider
TestResponse::macro('assertJsonPaths', function ($path, $expected) {
    foreach ($this->json($path) as $real) {
        PHPUnit::assertEquals($expected, $real);
    }

    return $this;
});

// then refactor the test 
public function test_users_can_get_their_categories_list()
{
    factory(Category::class, 5)->create();
    $user = factory(User::class)->create();
    Passport::actingAs($user);

    $this->get('api/categories')
        ->assertSuccessful()
        ->assertJsonCount(5)
        ->assertJsonPaths('*.user_id', $user->id)
        ->assertJsonStructure([
