StillKnotKnown 4f1b7b2a95 test: improve backend memory system test coverage to 100% (#1780)
* test: add comprehensive test suite for backend memory system

Add 25 test files covering the integrations/graphiti memory system:
- Core module tests (client, queries, search, graphiti, schema)
- Migration tests (migrate_embeddings, kuzu_driver_patched)
- Provider tests (6 embedder + 6 LLM providers)
- Cross-encoder and config tests

Coverage achievements:
- 134 passing tests for core modules
- graphiti.py: 95%, queries.py: 87%, client.py: 96%
- cross_encoder.py: 74%, search.py: 95%, config.py: 94%
- Overall: 51% coverage (up from 46%)

Tests were moved from apps/backend/tests/ (gitignored) to
tests/integrations/ to be included in version control.

* test: add pytest configuration with markers for long-running tests

Add pyproject.toml for backend testing with:
- pytest markers for slow/integration/smoke tests
- optimized test configuration (maxfail, -v, -m "not slow")
- coverage settings with HTML and terminal reporting
- mypy configuration for type checking

This ensures long-running tests are excluded from default CI runs
while maintaining comprehensive test coverage reporting.

* fix: resolve F821 undefined name errors in test_kuzu_driver_patched.py

Fixed 14 F821 undefined name errors for mock_kuzu_driver_module by
adding proper local definitions before each patch.dict call in test
methods that use the mock.

Also fixed encoding issue in test_config.py (added encoding='utf-8' to
open() call).

All 426 tests now pass with pre-commit hooks successful.

* test: add tests for __init__.py and providers.py modules

Added comprehensive test coverage for:
- integrations/graphiti/__init__.py: Test lazy import __getattr__ functionality
- integrations/graphiti/providers.py: Test re-exported items from graphiti_providers

These modules now have 100% test coverage.

* test: add error path tests for cross_encoder.py

Added tests for:
- ImportError when graphiti_core modules not available
- Exception during reranker creation

cross_encoder.py now has 100% test coverage (23 statements).

* test: add test for Windows non-pywin32 import error

Added test for Windows-specific import error that is not a pywin32 error,
which logs a debug message instead of an error.

client.py coverage improved from 95.9% to 96.7% (4 lines remaining).

* test: add fast success path tests for azure_openai_llm and openrouter_llm

Added fast (non-slow) tests for the success paths in:
- azure_openai_llm.py: Now 100% coverage (was 83.3%)

* fix: address AndyMik90 PR review feedback - code duplication

Fixes:
- Extract repeated sys.modules cleanup into isolate_kuzu_module fixture in test_client.py
- Add _build_sys_modules_dict helper to eliminate 25-line sys.modules patching duplication in test_kuzu_driver_patched.py
- Fix inconsistent pragma in memory.py (lines 95-96 now both marked)
- Update testpaths in pyproject.toml to include "integrations/graphiti/tests"
- Remove duplicate test___init__.py file
- Remove coverage.json from git and add to .gitignore

Code reduction: 598 deletions vs 310 insertions
All 666 tests passing.

* fix: address detailed PR review feedback on test files

Fixes:
- test_client.py: Removed redundant _apply_ladybug_monkeypatch() call, fixed convoluted pywin32 assertion, used call.kwargs directly
- test_cross_encoder.py: Extracted duplicate sys.modules mocking into graphiti_core_mocks fixture
- test_kuzu_driver_patched.py: Parameterized slow tests, split test_execute_query_handles_empty_results, updated build_indices assertions to check SQL strings
- test_memory.py: Fixed fragile import mocking to only raise for graphiti_core imports
- test_migrate_embeddings.py: Created distinct MagicMock instances per iteration to avoid mutation issues
- test_provider_naming.py: Removed print statements and script-entry guard, used explicit config values, strengthened assertions
- test_providers_facade.py: Extracted expected_exports list into module-level constant
- test_providers_google.py: Extracted repeated MagicMock setup into google_genai_mock fixture
- test_providers_llm_openai.py: Replaced tautological assertions with concrete expectations and parametrized slow tests
- search.py: Fixed min_score filtering to handle None scores by normalizing to 0.0

All 667 tests passing.

* fix: address additional detailed PR review feedback

Fixes:
- search.py: Normalized result.score in get_patterns_and_gotchas and get_similar_task_outcomes to handle None values
- test_client.py: Fixed test_returns_false_when_ladybug_unavailable to ensure graphiti_core is present, extracted repeated boilerplate into graphiti_mocks fixture
- test_cross_encoder.py: Added concrete assertion for base_url value, removed original_func indirection
- test_kuzu_driver_patched.py: Added module-level MockKuzuDriver class, added DROP_FTS_INDEX assertion to test_build_indices_with_delete_existing
- test_memory.py: Fixed tautological else branch with concrete assertion
- test_migrate_embeddings.py: Renamed mock configs to match actual roles (current_config, source_config, target_config)
- test_provider_naming.py: Removed unused pytest import and unused embedding_model variable
- test_providers_google.py: Added sys.modules patching to test_google_embedder_init_import_error
- test_providers_llm_openai.py: Fixed patch target path for OpenAIClient to use consuming module's namespace

All 667 tests passing.

* fix: remove duplicate tests and improve test coverage

Fixes:
- test_client.py: Removed duplicate test_initialize_returns_false_on_ladybug_unavailable
- test_client.py: Removed duplicate test_updates_state_with_init_info
- test_cross_encoder.py: Changed unused result variable to _ discard
- test_kuzu_driver_patched.py: Removed duplicate test_execute_query_returns_rows

- test_provider_naming.py: Changed `if dim:` to `if dim is not None:`, converted for-loop to pytest.mark.parametrize

All 668 tests passing.

* fix: address PR review feedback - score normalization and code duplication

- Fix score normalization to correctly handle score of 0 vs None
  - Changed `getattr(result, "score", None) or 0.0` to explicit None check
  - This prevents treating a legitimate score of 0 as None

- Refactor test_client.py to eliminate code duplication
  - Created _make_mock_config() helper function for consistent mock config creation
  - Extended graphiti_mocks fixture with better documentation
  - Converted 15+ tests to use the fixture instead of duplicated boilerplate
  - Removed ~330 net lines of duplicated setup/teardown code

Addresses HIGH and MEDIUM severity issues from PR review.

* fix: address remaining medium severity PR review issues

1. Move standalone test scripts out of tests/ directory
   - Renamed test_graphiti_memory.py -> run_graphiti_memory_test.py
   - Renamed test_ollama_embedding_memory.py -> run_ollama_embedding_test.py
   - These are standalone executable scripts with argparse, not pytest tests

2. Remove fragile pytest_collection_modifyitems filtering
   - No longer needed since standalone scripts moved out of tests/
   - Only keep validator function filtering (legitimate use case)

3. Rename shadowing fixtures in test_graphiti.py
   - temp_spec_dir -> graphiti_test_spec_dir
   - temp_project_dir -> graphiti_test_project_dir
   - mock_config -> mock_graphiti_config
   - mock_state -> mock_graphiti_state
   - Names now indicate intentional difference from conftest fixtures

Addresses 3 MEDIUM severity issues from PR review.

* fix: update test_graphiti_connection for embedded LadybugDB

The function was using outdated FalkorDB configuration attributes
(falkordb_host, falkordb_port, falkordb_password) that no longer exist
on GraphitiConfig. Updated to use embedded LadybugDB via
create_patched_kuzu_driver with db_path instead.

- Replace FalkorDriver with patched KuzuDriver for embedded DB
- Use config.get_db_path() instead of host/port credentials
- Update tests to mock the new driver creation path
- Rename test to reflect new driver type

* fix: address PR review feedback on conftest fixtures and test comments

- Fix mock_config fixture to use actual GraphitiConfig fields (database
  instead of dataset_name, openai_model instead of llm_model, etc.)
- Fix mock_state fixture to use actual GraphitiState fields
- Fix mock_env_vars to use correct env var names (GRAPHITI_DATABASE,
  OPENAI_MODEL, OPENAI_EMBEDDING_MODEL)
- Fix test_search.py comments to accurately describe None->0.0 score
  conversion, add assertion to verify the behavior
- Update pyproject.toml testpaths to include core/workspace/tests
  and remove non-existent 'tests' directory

* fix: address all remaining PR review feedback including LOW severity

MEDIUM fixes:
- Update usage docs in run_graphiti_memory_test.py to reference new filename
- Update usage docs in run_ollama_embedding_test.py to reference new filename

LOW fixes:
- Fix get_relevant_context docstring: add min_score param, correct
  include_project_context description (works in SPEC mode, not PROJECT mode)
- Make mock_embedder fixture deterministic using [0.1] * 1536 instead of
  random values for reproducibility
- Add test coverage for None score handling in get_similar_task_outcomes
  and get_patterns_and_gotchas methods
