Filamentphp testing with Pest Call to undefined function Pest\Livewire\livewire()

Currently I am using laravel, filamentphp, and pest for testing. I went through the filament testing documentation, but when I try to run the following testing:

use function Pest\Livewire\livewire;
 
it('can list posts', function () {
    $posts = Post::factory()->count(10)->create();
 
    livewire(PostResource\Pages\ListPosts::class)
        ->assertCanSeeTableRecords($posts);
});

I get this error Call to undefined function Pest\Livewire\livewire().

More details:

Mainly it’s because of your project is missing a package that didn’t mentioned in the documentation unfortunately 😔.

How to solve it?

You need to install this package:

composer require pestphp/pest-plugin-livewire --dev

Now, your editor e.g. VS Code should able to detect this:

use function Pest\Livewire\livewire;

BTW, if you have still issue, maybe use composer dump-autoload.

Thanks.
