[Test] [Issue- 221] : Add unit test for ChatBot

[kallel-anobom]

Description

This change includes the setup of mocks for dependencies used in the ChatBot component tests. It mocks the idGenerator, ChatBotContext, ChatBotLoader, and ChatBotContainer to isolate the component being tested and ensure that the tests are not affected by the actual implementations of these dependencies.

Closes #221
