Add Unit Tests for Alert System

[Somya2010]

Description

The alert system is a critical component of the project, but it lacks unit tests. Adding tests will ensure that it works as expected and catches regressions.

Steps to Implement

1. Identify the main functionalities of the alert system.
2. Write unit tests for each functionality using a testing framework like pytest.
3. Mock external dependencies where necessary.

Expected Outcome

A robust suite of tests that validates the functionality of the alert system.
