Greptile Summary

This PR consolidates PrefectWorkerHealthTool tests by deleting the co-located tool_test.py and migrating all tests into tests/tools/test_prefect_worker_health_tool.py, introducing a shared @pytest.fixture to remove per-test boilerplate and adding several new, more-granular test cases alongside the existing ones. The migration itself is clean, but the new tests were added without removing the pre-existing tests that cover the same scenarios, leaving three duplicate pairs in the file.

Confidence Score: 5/5

Safe to merge — the migration is correct, no tests are lost, and the only finding is duplicate test cases (P2).

All findings are P2 style issues. The test logic itself is correct, no functionality is changed, and the old file is cleanly deleted. Duplicate tests are a minor maintenance concern but do not affect correctness or CI reliability.

tests/tools/test_prefect_worker_health_tool.py — three redundant test functions should be removed.

Hey @hruico, I walked through the diff and the migration itself looks good: the old app/tools/PrefectWorkerHealthTool/tool_test.py is fully covered by the new tests in tests/tools/test_prefect_worker_health_tool.py, and CI is green ✅

There are a few redundant tests left in the consolidated file though:

• test_is_available_requires_connection_verified overlaps with the new pair:
  • test_is_available_when_connection_verified
  • test_is_available_false_without_connection_verified
• test_run_returns_unavailable_when_no_api_url overlaps with:
  • test_run_returns_unavailable_without_api_url
  • test_run_returns_unavailable_for_whitespace_only_api_url

These older tests are now strictly less expressive than the new ones and just add noise. I suggest deleting:

• test_is_available_requires_connection_verified
• test_run_returns_unavailable_when_no_api_url

This matches the earlier Greptile note about duplicate coverage. After that small cleanup, we can rely on CI and merge 👍
