Livewire test with mocking

Hello,

I have a few questions about mock in Livewire test files.

My UploadMedia component uses a MediaService i want mock.

$this->instance(
    MediaService::class,
    Mockery::mock(MediaService::class, function (MockInterface $mock) {
        $mock->shouldReceive('store')
            ->andReturn('image_hash');
    })
);

$component = Livewire::test(UploadMedia::class);

$component
    ->set('mediaType', 'image')
    ->set('media', $image)
    ->call('updated')
    ->assertEmitted('mediaUpdated');

However when i call updated my mock doesn’t effect :

Mockery\Exception\InvalidCountException: Method store(<Any Arguments>) from Mockery_1__Tests_Livewire_Form_MediaService should be called

I have the feeling that Livewire::test does not use the mock.

Any ideas?

Thx !
