"""
Test module for BaseResource

Test Categories:
1. HTTP methods - _get, _post, _put, _delete
2. URL building - _build_url with path joining
3. Response handling - Success (200-299), errors (4xx, 5xx)
4. Error mapping - HTTP status → custom exceptions
5. Request headers - User-Agent, Content-Type, Accept
