Class "GuzzleHttp\HandlerStack" not found in (laravel) Pest-Test

Question

i want to test an api-client. the api-client uses Illuminate\Support\Facades\Http to make requests. when i use it in tinker everything is ok:

> $response = Bitwarden::listItems()
= Illuminate\Support\Collection {#6782
    all: [
      {#6854
        +"object": "item",
       ....
      },
    ],
  }

My test looks like this:

it('can list the items', function () {
   $response = Bitwarden::listItems();
   expect($response)->toBeArray();
});

and result is

 FAILED  Tests\BitwardenCliTest > it can list the items                              Error   
  Class "GuzzleHttp\HandlerStack" not found

i guess i missed something in setting up pest. please give me a hint. thx :)

i want the client to work in test like it does in tinker

since i'm using jetstream in this project, i "reinstalled" it using pest as testing-framework like mentioned here https://jetstream.laravel.com/installation.html#:~:text=If%20you%20would%20like%20to%20use%20Pest%20PHP%20for%20testing%2C%20you%20may%20use%20the%20%2D%2Dpest%20switch%20to%20install%20a%20Pest%20test%20suite%20instead%20of%20the%20default%20PHPUnit%20test%20suite.

now my tests are passing!
