I have entities which are managed by two entity managers in Symfony 4 project and I would like to load fixtures from both connections for functional tests. For instance :
class AdapterTest extends KernelTestCase
{
    use FixturesTrait;
    ...
    protected function setUp(): void
    {
        self::bootKernel();
        // Not working, just for example
        $this->loadFixtures([CounterFixtures::class], false, 'counter');
        $this->loadFixtures([CountryFixtures::class]);
        ...
    }
    ...
}
Unfortunatly, tables are dropped and only tables related to last entity manager connection are loaded.
I use LiipTestFixturesBundle v1.9.1.
Does this bundle support it or do you know how I can do that?
                        
The second parameter of
loadFixturesis$append, its value isfalseby default.It should work with this code:
