test: Macae v4 unittestcases kd by Kingshuk-Microsoft · Pull Request #790 · microsoft/Multi-Agent-Custom-Automation-Engine-Solution-Accelerator

Kingshuk-Microsoft · 2026-01-28T10:56:00Z

Purpose

This pull request introduces significant improvements to testing infrastructure, test coverage, and code organization for the backend, especially in the authentication module. The main changes include adding comprehensive unit and integration tests for authentication utilities, updating test configuration for better maintainability and coverage, and refactoring imports for clarity and correctness.

Testing Infrastructure & Coverage Improvements:

Added a .coveragerc configuration file to standardize code coverage measurement, specifying source directories, files to omit, and exclusion patterns for coverage reporting.
Updated the GitHub Actions workflow (.github/workflows/test.yml) to use the new coverage configuration and simplified ignore patterns for test execution.
Enhanced pytest.ini with explicit Python paths, test discovery patterns, and test class/function naming conventions for improved test discovery and execution.

Authentication Module Testing:

Added comprehensive unit and integration tests for backend.auth.auth_utils in src/tests/backend/auth/test_auth_utils.py, covering various scenarios including valid/invalid headers, base64 decoding, error handling, and integration flows.
Introduced fixtures and test configuration in src/tests/backend/auth/conftest.py to support reusable test data and setup for authentication tests.
Created empty __init__.py files for test packages to ensure correct package recognition and import behavior by pytest. [1] [2]

Code Organization & Import Refactoring:

Refactored relative imports to absolute imports within backend modules for clarity and to prevent import errors, especially in settings.py, messages.py, and plan_to_mplan_converter.py. [1] [2] [3]
Added placeholder __init__.py files to src and src/backend to clarify package structure. [1] [2]

Pull request overview

This PR significantly expands backend v4 unit/integration test coverage (auth, services, agent lifecycle, utilities) and updates CI to enforce standardized coverage reporting.

Changes:

Added extensive pytest/unittest suites across v4 modules (agents, services, router, callbacks) plus core backend utilities (db factory, dates, events, middleware).
Added test package __init__.py files to ensure consistent test package discovery/imports.
Updated GitHub Actions workflow to run coverage with .coveragerc and enforce an 80% threshold.

The if ...; then ... else "No tests found" logic will treat any pytest failure (including real test failures/import errors) as “no tests found” and not fail the job, because both pytest commands are inside the if condition and the first command silences all output. Consider explicitly handling pytest exit code 5 (no tests collected) and failing on any other non-zero exit; also avoid depending on bc (may be missing) by doing the threshold comparison in Python.

src/tests/backend/v4/api/test_router.py

+                # Import failed but we still get some coverage

+                self.assertTrue(True, "Attempted router import with errors")


This test always passes even when the router import fails, which can mask real regressions (e.g., broken imports, missing dependencies, syntax errors). If the intent is coverage + correctness, the import failure should fail the test (or at least only tolerate “no tests collected” / an explicitly documented exception type), otherwise CI can go green with a broken API module.

Suggested change

print(f"Router import failed with ImportError: {e}")

# Don't fail the test - partial coverage is better than none

self.assertTrue(True, "Attempted router import")

except Exception as e:

# Other errors but we still get some coverage

print(f"Router import failed with error: {e}")

# Don't fail the test

# Other unexpected errors during router import or initialization

Writing directly into sys.modules at import time (module scope) is very likely to leak across the test run and make tests order-dependent. Prefer a fixture that uses monkeypatch/patch.dict(sys.modules, ...) to inject stubs and then automatically restore them after each test/module.

src/tests/backend/test_app.py

+# Check if v4 modules are already properly imported (means we're in a full test run)
+_router_module = sys.modules.get('backend.v4.api.router')
+_has_real_router = (_router_module is not None and 
+                   hasattr(_router_module, 'PlanService'))
+
+if not _has_real_router:
+    # We're running in isolation - need to mock v4 imports
+    # This prevents relative import issues from v4.api.router


This conditional mocking makes the test behavior depend on import order (whether backend.v4.api.router happened to be imported earlier in the session). That can cause flaky CI (“passes locally, fails in CI” depending on collection/import order). Prefer always scoping the sys.modules mocking to a fixture/context manager (or always using a controlled import path) so the test is deterministic regardless of test ordering.

These sys.modules[...] mocks are duplicated back-to-back (and overwrite each other). Removing the duplicate block will reduce confusion and make it clearer which mocks are intended to be active.

There’s duplicated import importlib.util and repeated BaseAPIService loading/setup logic in this file. Consolidating the import and ensuring BaseAPIService is loaded exactly once will reduce brittleness and make future edits less error-prone (especially with the complex sys.modules patching for coverage).

+        # So we just verify the initial registration worked
+        self.assertIn(agent_id, self.registry._agent_metadata)


The test description says GC/weakref cleanup is non-deterministic, but the assertion checks for a specific post-GC state (agent_id still present in metadata). This is likely to be flaky if the implementation changes to clean metadata on GC (or if GC timing differs). Consider asserting only deterministic behavior (e.g., registration added metadata), or explicitly defining what the registry guarantees about metadata lifetime (and testing that contract).

Suggested change

# Delete the agent reference

agent_id = id(agent)

del agent

# Force garbage collection

import gc

gc.collect()

# The weak reference should be cleaned up automatically

# Note: This might not always work immediately due to Python's GC behavior

# So we just verify the initial registration worked

self.assertIn(agent_id, self.registry._agent_metadata)

# Verify that registration added metadata while the agent is still strongly referenced.

agent_id = id(agent)

self.assertIn(agent_id, self.registry._agent_metadata)

# Delete the agent reference and force garbage collection to exercise weakref cleanup.

# We intentionally do not assert on post-GC internal state, as GC timing/cleanup is

# implementation- and runtime-dependent.

+                pass


Catching and ignoring ImportError here means the test can pass without validating the fallback path at all. Instead of tolerating an import failure, it would be more robust to patch the dependency that triggers the ImportError (e.g., provide a fake sample_user module/object via patch.dict(sys.modules, ...)) so you can assert the actual returned fallback user details deterministically.
