Problem: - There are no unit tests for `MACAddress` class. This makes it difficult to refactor and ensure the same behavior. - `m_data` private member variable is uninitialized leading to undefined behavior of `is_zero()`. Solution: - Add unit tests to cover basic functionality. - Initialize `m_data`.
