Laravel unit test always error with code 401 - php

Question

So I'm making unit tests using laravel, I have 50 tests. but when a test that requires auth, the test automatically fails and raises a 401 error
Expected status code 404 but received 401. Failed asserting that 404 is identical to 401.
for the failed test, like this is the code. I use actingAs to work around auth, but it always fails
public function testDenyNonAdminUserAccess()
{
$user = factory(User::class)->create();
$author = factory(Author::class)->create();
$response = $this
->actingAs($user)
->postJson('/api/books', [
'isbn' => '9788328302341',
'title' => 'Clean code',
'description' => 'Lorem ipsum',
'authors' => [$author->id],
]);
$response->assertStatus(403);
}
even though when I use postman to insert data, it always works and there are no problems. is there any solution?
I also put the middleware in the controller
public function __construct()
{
$this->middleware(['auth:api', 'auth.admin'])->except('index');
}
is there any solution?

To me, It seems there is no user in your memory database.
Try this one to check whether there are users saved in your DB or not.
User::factory(10)->create();
$this->assertEquals(10, User::get()->count());
If it is, try to login a specific user like this:
$user = User::find(1);
$this->actingAs($user);
