assertRedirect to a URL with an ID when testing

Here's my Pest code which I write by looking at both the FilamentPHP and Livewire testing docs:

it('redirects to view when post created', function () {
    livewire(CreatePost::class)
        ->fillForm([
            'title' => 'Test title'
        ])
        ->call('create')
        ->assertRedirect(ViewPost::class);
});

it('redirects to view when post created', function () {
    livewire(CreatePost::class)
        ->fillForm([
            'title' => 'Test title'
        ])
        ->call('create')
        ->assertRedirect(ViewPost::class);
});

This fails saying,

Missing required parameter for [Route: filament.admin.resources.posts.view] [URI: admin/posts/{record}] [Missing parameter: record]

There doesn't seem to be a way to pass a param to this, so I changed it slightly:

->assertRedirect(route(
    'filament.admin.resources.posts.view', 
    ['record' => 16]
));

->assertRedirect(route(
    'filament.admin.resources.posts.view', 
    ['record' => 16]
));

Ok, that works. But obviously I'm hardcoding the ID. How am I supposed to get the ID when filling a form like this so that I can assert that it redirected to the correct route dynamically?

Solution:

Query for the latest post. Then you’ll have the id from the create method. For the redirect you should use PostResource::getUrl(‘view’, [‘record’ => $post])...

Nice, thank you! Answers both of my questions 🙂 Here's what I ended up with... I'm posting it here in case it helps anyone else or in case I forget and search again in a few weeks 🤪

->assertRedirect(
    PostResource::getUrl('view', ['record' => Post::latest()->first()->id])
)

->assertRedirect(
    PostResource::getUrl('view', ['record' => Post::latest()->first()->id])
)
