This import path triggers smc_trading_agent/monitoring/__init__.py first, which eagerly imports enhanced_monitoring and requires psutil; in a clean environment using the repo requirements, that dependency is missing and test collection fails with ModuleNotFoundError before any test executes. The test should load health_monitor in a way that avoids package-level eager imports (or the package init should be made lazy/optional) so this suite is runnable in CI.

Patching HealthMonitor.perform_health_checks and then asserting the patched return payload does not validate real behavior; this test will pass even if the implementation is broken, so it adds false confidence rather than regression coverage. Mock downstream dependencies instead and exercise the actual perform_health_checks method.
Useful? React with 👍 / 👎.

Pull request overview
Adds pytest coverage for the lightweight HealthMonitor implementation in smc_trading_agent/monitoring/health_monitor.py, focusing on initialization and the shape/content of perform_health_checks() results.
Changes:
- Introduces a new test module covering
HealthMonitorinitialization andperform_health_checks()outputs. - Adds assertions for returned
HealthStatusfield types/values based on the current dummy implementation. - Demonstrates mocking via
unittest.mock.patch(currently by patching the method under test).
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

Import order/formatting in this new test file is unlikely to pass the repo’s formatting/lint gates (Black + isort). For example, standard-library imports (unittest.mock) should be separated and placed before third-party (pytest), and the parenthesized import should include a trailing comma so Black can format it consistently.

This test patches HealthMonitor.perform_health_checks and then asserts on the patched return value, so it doesn’t exercise any HealthMonitor logic (and can inflate perceived coverage without validating behavior). Consider removing it or instead mocking dependencies inside perform_health_checks (or, with the current dummy implementation, patch health_monitor.services and assert the real method builds HealthStatus objects from it).

When patching an async method, prefer new_callable=AsyncMock (as done in other tests) so the test doesn’t rely on Python’s automatic AsyncMock inference behavior for coroutine functions.
