Unit test generation was requested by @coderabbitai[bot].

The following files were modified:

  • money-machine/src-python/tests/test_config_internals.py
  • money-machine/src-python/tests/test_ipc_auth.py
  • money-machine/src-python/tests/test_signal_generator_metadata.py
  • money-machine/src-python/tests/test_trading_core_validate.py

Greptile Summary

This PR adds two new unit test files generated by CodeRabbit, covering the private helpers in utils/config.py (_without_secrets, _deep_merge, save_config error path) and the validate_config_update function in engine/trading_core.py. The tests were verified against the actual implementations and the assertions are correct.

  • test_config_internals.py exercises scalar pass-through, nested dict/list secret stripping, in-place merge semantics, and the save_config error return path via monkeypatch; all assertions match the real implementation.
  • test_trading_core_validate.py provides thorough boundary, type, and whitelist coverage for validate_config_update; one test function carries a misleading name (test_integer_value_for_risk_coerced_to_float) that implies a risk-key assertion while the body tests initial_balance, duplicating the adjacent test_integer_value_is_accepted_and_coerced_to_float.

Confidence Score: 4/5

Safe to merge — adds test-only files with no changes to production code; all assertions align with the actual implementations.

Both test files are additive and touch no production paths. All assertions were verified against the real utils/config.py and engine/trading_core.py implementations. The only issues are a misleading test name that duplicates a nearby test, and a missing trailing newline.

No files require special attention; test_trading_core_validate.py has a minor naming inconsistency worth fixing before it causes confusion.

Important Files Changed

Filename Overview
money-machine/src-python/tests/test_config_internals.py New test file covering _without_secrets, _deep_merge, and save_config error path; tests align with the actual implementation but is missing a trailing newline.
money-machine/src-python/tests/test_trading_core_validate.py New test file for validate_config_update with strong boundary and type coverage; one test function has a misleading name that implies it tests a risk key while actually testing initial_balance, duplicating an adjacent test.

P2 Misleading test name — the function is named test_integer_value_for_risk_coerced_to_float, implying it exercises a risk-related key, but the body tests initial_balance. It also duplicates test_integer_value_is_accepted_and_coerced_to_float which tests the identical assertion. Rename it to reflect what it actually exercises, or remove the duplicate.

P2 File is missing a trailing newline. Most linters and editors (including editorconfig, pre-commit, and the POSIX standard) expect text files to end with a newline; its absence can cause noisy diffs.

Suggested change
result = save_config({"max_risk_per_trade": 0.02})
assert result is False
result = save_config({"max_risk_per_trade": 0.02})
assert result is False
