Laravel策略在测试中的工作方式有所不同

use Tests\TestCase;
use App\Models\User;
use App\Models\Post;
use App\Policies\PostPolicy;

class PostPolicyTest extends TestCase
{
    public function testUserCanUpdateOwnPost()
    {
        $user = User::factory()->create();
        $post = Post::factory()->create(['user_id' => $user->id]);

        $policy = new PostPolicy();

        $this->assertTrue($policy->update($user, $post));
    }

    public function testUserCannotUpdateOtherUserPost()
    {
        $user1 = User::factory()->create();
        $user2 = User::factory()->create();
        $post = Post::factory()->create(['user_id' => $user2->id]);

        $policy = new PostPolicy();

        $this->assertFalse($policy->update($user1, $post));
    }
}
