Testing Laravel Livewire sorting component - laravel-livewire

Question

I'm trying to test a sort by call for a table, The sort by works in practice but I cannot generate a failing test, my test always passes so I'm not testing it correctly.
Steps to Reproduce:
This is the test:
Livewire::test(Roles::class)
->call('sortBy', 'blah')
->assertSet('sortField', 'blah')
->call('roles')
->assertStatus(200);
the param blah should match a database column, I don't have a column called blah so should fail, but it passes.
the component:
class Roles extends Component
{
use WithPagination;
public $paginate;
public $query;
public $sortField = 'name';
public $sortAsc = true;
protected $queryString = ['query'];
public function render()
{
abort_if_cannot('view_roles');
return view('livewire.roles.roles');
}
public function builder()
{
return Role::orderBy($this->sortField, $this->sortAsc ? 'asc' : 'desc');
}
public function sortBy($field)
{
if ($this->sortField === $field) {
$this->sortAsc = ! $this->sortAsc;
} else {
$this->sortAsc = true;
}
$this->sortField = $field;
}
public function roles()
{
$query = $this->builder();
if ($this->query) {
$query->where('name', 'like', '%'.$this->query.'%');
}
return $query->paginate($this->paginate);
}
public function deleteRole($id): void
{
abort_if_cannot('delete_roles');
$this->builder()->findOrFail($id)->delete();
$this->dispatchBrowserEvent('close-modal');
}
}
Are you using the latest version of Livewire: v2.3.6
If I attempt to run:
wire:click.prevent="sortBy('blah')
Then I do get an SQL error as expected.
Anyone know how I can update my test to actually see there's an error.
