"""Unit tests for the Evaluation Queue functionality.

Tests cover:
  - get_evaluation_queue_df correctly loads and categorizes queue entries
  - Status categorization: Finished, Running, Pending (incl. Waiting/Rerun)
  - Column completeness and data types
  - Robustness against entries missing expected fields (e.g. quant entries)
  - Count consistency: sum of 3 queues == total parseable entries
  - No crashes on the real cache_git/status data
