You can also use getObjectForTrait , then assert the actual result if you want.

class YourTraitTest extends TestCase
{
    public function testGetQueueConfigFactoryWillCreateConfig()
    {
        $obj = $this->getObjectForTrait(YourTrait::class);

        $config = $obj->getQueueConfigFactory();

        $this->assertInstanceOf(QueueConfigFactory::class, $config);
    }

    public function testGetQueueServiceWithoutInstanceWillCreateConfig()
    {
        $obj = $this->getObjectForTrait(YourTrait::class);

        $service = $obj->getQueueService();

        $this->assertInstanceOf(QueueService::class, $service);
    }
}
