Help creating proper redirect assertion tests with Spatie Sluggable

[eballeste]

given a named route admin.work.show with the following pattern: /works/{work}

and given the following simple test:

public function managers_can_create_works()
{
    $this->createManager();
    $this->loginManager();

    $workRawAttributes = Work::factory()->raw();
        
    // create a new work
    $response = $this->from(route('admin.work.create'))
        ->post(route('admin.work.store'), $workRawAttributes);

    // assert that the the db has this work
    $this->assertDatabaseHas('works', $workRawAttributes);

    // and assert that we are redirected to the work view page
    $response->assertRedirect(route('admin.work.show', [missing parameter]));
}

my test fails in the second assert because I am missing the required {work} parameter from my url.
How do I access either the slug or the model generated in my Work controller's store method?

a possible solution would be to generate the slug from the raw attributes in my test using Str::slug and use that instead for the final assertion but something feels off about it. I think it's because, in this scenario, I'm generating this slug with Laravel and comparing it to a slug generated by Sluggable which somehow feels nimble to me. I feel like this could produce unexpected results but please correct me if I am wrong or if I shouldn't be worrying about this, thanks ✌️

this works but feels... off?

public function managers_can_create_works()
{
    $this->createManager();
    $this->loginManager();

    $workRawAttributes = Work::factory()->raw();
    $slug = Str::slug($workRawAttributes['name']); // i don't like this
        
    // create a new work
    $response = $this->from(route('admin.work.create'))
        ->post(route('admin.work.store'), $workRawAttributes);

    // assert that the the db has this work
    $this->assertDatabaseHas('works', $workRawAttributes);

    // and assert that we are redirected to the work view page
    $response->assertRedirect(route('admin.work.show', $slug));
}
