Testing sorting component

#1

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.
