Testing cases are:

• Onboarding (signing up and hitting the paywall).

• Creating a schedule (employer).

• Adding employees.

• Joining a schedule (employee).

• Upgrading to premium subscriptions (employee + employer).

• Using premium subscriptions (employee + employer, check each subscription and its benefits).

• Building schedules (for employers) / previews (for employees) - with expected results that the algorithm works and calculates proper shifts out of the priorities (makes order).
