Create Unit Tests

[chrisdedman]

Description

We need to add unit tests to ensure the software's reliability and correctness. This will help us catch regressions early and improve overall code quality.

Tasks

• Identify key functions and methods that require testing.
• Write unit tests for the identified functions using a suitable testing framework (Qt Test).
• Ensure tests cover a variety of scenarios, including edge cases.
• Document the testing process and update the Wiki with instructions on running tests locally.

Requirements

• Tests should be written in a separate test file, e.g., test_[module_name].cpp.
• Use mock objects or stubs where necessary to isolate the unit under test.
• Target at least 80% code coverage.
• Ensure that tests are independent and can be run in any order.
