Description:
So, I've just cloned this repo, ran tests for datepicker component, all tests passed. But I think there is a problem with subscriptions in those tests, e.g:

But RxJS throws error asynchorinously since version 6 https://v6.rxjs.dev/guide/v6/migration#typescript-prototype-operators . You can even add throw new Error('Should fail') to the subscription callback, and the test will pass. So some of these tests fail silently. In this case, this code block should look some thing like this:

    let view = await firstValueFrom(datepickerContainerInstance[`_store`].select((state) => state));
    expect(view.maxDate).toEqual(correctDateEnd);
