Add comprehensive unit tests for all 12 tools
- Add unit tests for 7 previously untested tools: - pia_search_content_gao - pia_search_content_oig - pia_search_content_crs - pia_search_content_doj - pia_search_content_congress - pia_search_content_executive_orders - fetch - Each tool now has tests for: - Success scenarios with mocked API responses - Error handling when API key is missing - HTTP error handling - Fix test environment isolation by clearing environment variables - Add missing os import for environment mocking - Achieve 100% tool test coverage (12/12 tools tested) - All 23 tests now pass The GitHub Actions workflows are already configured to run these tests automatically on push and pull requests.
