Target class [livewire] does not exist.

I have installed the Pest Livewire plugin according to the documentation:
https://pestphp.com/docs/plugins#livewire
I set up a TestCase, configuring the default user and panel.
I created the following simple test:

<?php

use App\Filament\App\Resources\ImportResource\Pages\ListImports;

use function Pest\Livewire\livewire;

it('can render the index page', function () {
    livewire(ListImports::class)
        ->assertSuccessful();
});

<?php

use App\Filament\App\Resources\ImportResource\Pages\ListImports;

use function Pest\Livewire\livewire;

it('can render the index page', function () {
    livewire(ListImports::class)
        ->assertSuccessful();
});

However, I receive the following error:

FAILED  Tests\Feature\Filament\Resources\ImportResourceTest > it can render the index page                              
BindingResolutionException   
Target class [livewire] does not exist.

FAILED  Tests\Feature\Filament\Resources\ImportResourceTest > it can render the index page

Target class [livewire] does not exist.

LeandroFerreira•5d ago

add the dd inside the test..

Héctor Q. TorresOP•5d ago

My bad 🤣 Ok, return 'false'

LeandroFerreira•5d ago

what is the APP_ENV value from phpunit.xml file?

Héctor Q. TorresOP•5d ago

But I have an env.testing variable set, pointing to a test database.

LeandroFerreira•5d ago

are you using docker?

Héctor Q. TorresOP•5d ago

Yes, i am

LeandroFerreira•5d ago

are you running the test inside the container?

Héctor Q. TorresOP•5d ago

Yes, I am

I recommend double checking your env because definitely dd(app()->runningUnitTests()); should return true.. You could also try the same test in another Filament fresh install

I think this will be better, thank you for your time. If I figure out the problem, I’ll come back here with the solution. I discovered the problem. Actually, I had started the project using the PHPUnit package (since I was used to using it for API tests). However, after creating a new project from scratch and choosing Pest, I noticed that a file is created: /tests/Pest.php:

<?php

pest()->extend(Tests\TestCase::class)
 // ->use(Illuminate\Foundation\Testing\RefreshDatabase::class)
    ->in('Feature');

expect()->extend('toBeOne', function () {
    return $this->toBe(1);
});

function something()
{
    // ..
}

<?php

pest()->extend(Tests\TestCase::class)
 // ->use(Illuminate\Foundation\Testing\RefreshDatabase::class)
    ->in('Feature');

expect()->extend('toBeOne', function () {
    return $this->toBe(1);
});

function something()
{
    // ..
}

This way, everything worked correctly. Since my scenario involves multi-tenancy, I also needed to add the following setup in TestCase:

Filament::setTenant(MyEntityTenant::where(...)->first())

Filament::setTenant(MyEntityTenant::where(...)->first())

Thanks for the help again!
