Instructions

In this assignment, you will extend your App for PS $05-$ Extending Dental Appointment Scheduler assignment by writing unit tests using JUnit to ensure the correctness of your application's functionality. The goal is to practice writing effective tests that validate both the app's business logic and input validation.

Requirements

Ensure that JUnit is properly set up in your Android project. If it$$s not already configured, add JUnit to your project dependencies.

Write JUnit tests to validate the functionality of the Appointment class $($or equivalent class$)$ that stores appointment data.

Write JUnit tests to validate the input fields in your app, such as empty fields and date and time slot availability.

Ensure the app correctly identifies and handles attempts to book the same time slot for multiple patients.

Write tests to validate this functionality if your app includes navigation based on certain conditions $($e$.$g$.,$ directing the user to a favorite section$).$

Run your JUnit tests to ensure they pass. If any tests fail, debug and correct the issues in your app before resubmitting the tests.
