Testing RelationManagers

[titantwentyone]

For regular resources I usually employ two tests to ensure that my resources are rendering and pulling in the data needed. For example:

/**
 * @test
 */
public function it_will_list_the_camp_events()
{
    $campevent = CampEvent::factory()->create();
    $this->assertEquals(CampEvent::withoutGlobalScopes(), CampEventResource::getEloquentQuery());
    $this->assertEquals($campevent->id, CampEventResource::getEloquentQuery()->first()->id);
}

/**
 * @test
 */
public function it_will_display_the_correct_data_when_listing_camp_events()
{
    $campevent = CampEvent::factory()->create();

    Livewire::test(ListCampEvents::class)
        ->assertSee($campevent->date->format('Y-m-d'))
        ->assertSee($campevent->places_available)
        ->assertSee($campevent->capacity - $campevent->places_available)
        ->assertSee($campevent->capacity);
}

For relation managers, the second item is fine to replicate but the first is tricky as RelationManager doesn't have a static function for getEloquentQuery plus I'd need to pass in the ownerRecord somehow and I couldn't see anything equivalent. I know the test may seem like overkill but I do it for completeness and it's useful to run if the relationship changes for some reason. Also good to check it here than rely on assertSee which I find a bit "flakey". Is there a method to retrieve the Eloquent query used from a RelationManager for use within a test like this?

Ryan is working on some testing helpers for tables (and relation managers) right now :)

Brilliant. @ryangjchandler if you need some help with test driving this out, give me a shout.

@titantwentyone I have some news...

Oh wow! This looks awesome. Thank you!

Let me know if you're missing anything, we can easily add more stuff.

Hi @danharrin

I have facing some issues can you resolve it and share solution.

it('can hard delete device key relation manager', function () {
$device = Device::factory()->has(DeviceKey::factory()->count(1))->create();
$deviceKey = $device->deviceKeys->first();
$id = $deviceKey->id;

// Soft delete first
$deviceKey->delete();
expect(DeviceKey::withTrashed()->find($id))->not->toBeNull(); // Ensure soft deletion worked

Livewire::test(DeviceKeysRelationManager::class, [
    'ownerRecord' => $device,
    'pageClass' => EditDevice::class,
])
// ->assertTableActionExists('forceDelete')
->callTableAction(ForceDeleteAction::class, $deviceKey); // Correctly call the action with the record ID
// ->assertHasNoTableActionErrors();

$this->assertModelMissing($deviceKey);

// Now, the record should be completely gone
// expect(DeviceKey::withTrashed()->find($id))->toBeNull();

});

Error:
