Can't test throwing an exception. Help needed

[bu4ak]

PHP version: 8.0.2

Description
After adding 'httplug.factory.mock', the HttpMethodsClient is returned from the container.

Additional context

services.yaml

Http\Client\HttpClient $PDAHttpClient: '@httplug.client.pda'

test/httplug.yaml

httplug:
  clients:
    pda:
      factory: 'httplug.factory.mock'
      plugins:
        - vcr:
            mode: replay

PDAService.php

...
    public function __construct(
        HttpClient $PDAHttpClient
    ) {
         $this->httpClient = $PDAHttpClient;
    }
...

    public function executeRequest(RequestInterface $request): string
    {
            ....
            $response = $this->httpClient->sendRequest($request);
            ...
    }

ClientTest.php

...
$exception = new NetworkException('Could not resolve host', $this->createMock(Request::class));
$this->getContainer()->get('httplug.client.mock')->addException($exception);

$this->getContainer()->get(PDAService::class)->executeRequest(...);
...

Inside the PDAService constructor comes Http\Client\Common\HttpMethodsClient instead of Http\Mock\Client.
And instead of throwing an exception, it tries to find for a vcr fixture.

Other tests that work with vcr are performed correctly.

How can I test a case where an http client should throws a transport error?
