Test Improvements

Fixed Failing Tests (23 → 0)

  • Client tests: Corrected method signatures, return types, and Pydantic model usage
  • MCP server tests: Fixed FastMCP tool registration pattern understanding and authentication context mocking
  • Import errors: Updated import paths to match actual code structure

New Test Coverage

  • Rate limiting logic: Test client rate limiting behavior with time mocking
  • OAuth token failures: Test authentication error handling paths
  • Client initialization: Test edge cases and custom configurations
