Mock models / controller methods in tests

Hey!

I switched a while back from CI3 to CI4 but wasn't able to migrate my tests as I can't find a way to mock my models or even QueryBuilder like I did on CI3 with kenjis/ci-phpunit-test.
Is there any way to do something like that on CI4?

PHP Code:

$mock = $this->getDouble(
    'PreferenceModel',
    ['getPreference' => new Preference([])]
);

$this->request->setCallable(
    function ($CI) use ($mock) {
        $CI->PreferenceModel = $mock;
    }
); 


This code would mock $this->PreferenceModel in the controller.

Plus, is there any way to mock controller methods?

I'm still looking for a solution

In what context are you using it? Inside a controller? You can use PHPUnit's mock methods.
