From 60b01008610cbb3afe75151997b3d07464356889 Mon Sep 17 00:00:00 2001 From: Jeroen Schweitzer Date: Wed, 10 Dec 2025 02:09:38 +0100 Subject: [PATCH] test(library-desk): add comprehensive entity linking tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add test suite covering: - Entity mention detection (case-insensitive, whole-word matching, sorting) - Content link addition (protection of existing links, longest-first matching) - Integration tests (get entities with paths, create relationships, idempotency) - Multi-tenancy isolation tests All 17 tests passing. Validates entity linking functionality end-to-end. šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- .../library-desk/tests/test_entity_linking.py | 484 ++++++++++++++++++ 1 file changed, 484 insertions(+) create mode 100644 services/library-desk/tests/test_entity_linking.py diff --git a/services/library-desk/tests/test_entity_linking.py b/services/library-desk/tests/test_entity_linking.py new file mode 100644 index 0000000..6ad6b45 --- /dev/null +++ b/services/library-desk/tests/test_entity_linking.py @@ -0,0 +1,484 @@ +""" +Comprehensive tests for Entity Linking system. + +Tests cover: +- Finding entity mentions in pages +- Creating MENTIONS relationships in Neo4j +- Adding hyperlinks to wiki content +- Idempotency (safe to run multiple times) +- Protection of existing links (no nesting) +- Multi-tenancy isolation + +Run with: pytest tests/test_entity_linking.py -v -s +""" + +import pytest +import pytest_asyncio +from typing import AsyncGenerator + +from src.clients.neo4j_client import Neo4jClient +from src.clients.wikijs_client import WikiJSClient +from src.services.graph_service import GraphService +from src.services.wiki_service import WikiService +from src.routers.entity_linking import ( + find_entity_mentions, + add_entity_links_to_content, + get_entities_with_paths +) +from src.config import get_settings + +# Test user to isolate test data +TEST_USER = "entity-link-tester" + + +@pytest.fixture +def settings(): + """Get application settings.""" + return get_settings() + + +@pytest_asyncio.fixture +async def neo4j_client(settings) -> AsyncGenerator[Neo4jClient, None]: + """Get connected Neo4j client.""" + client = Neo4jClient( + uri=settings.neo4j_uri, + user=settings.neo4j_user, + password=settings.neo4j_password + ) + await client.connect() + yield client + await client.close() + + +@pytest_asyncio.fixture +async def wiki_client(settings) -> AsyncGenerator[WikiJSClient, None]: + """Get Wiki.js client.""" + client = WikiJSClient( + base_url=settings.wikijs_url, + username=settings.wikijs_username, + password=settings.wikijs_password + ) + yield client + + +@pytest_asyncio.fixture +async def graph_service(neo4j_client, wiki_client): + """Get GraphService instance.""" + return GraphService(neo4j_client, wiki_client) + + +@pytest_asyncio.fixture +async def wiki_service(wiki_client): + """Get WikiService instance.""" + return WikiService(wiki_client) + + +@pytest_asyncio.fixture +async def test_entities(graph_service): + """Create test entities in graph.""" + from src.core.multi_tenancy import get_neo4j_user_base_label + + user_base_label = get_neo4j_user_base_label(TEST_USER) + + # Clean up any existing test entities + cleanup_query = f""" + MATCH (n:{user_base_label}) + WHERE n.name IN ['Docker', 'Kubernetes', 'PostgreSQL'] + DETACH DELETE n + """ + await graph_service.neo4j.execute_query(cleanup_query) + + # Create test entities + create_query = f""" + CREATE (d:{user_base_label}:Technology {{name: 'Docker', type: 'technology'}}) + CREATE (k:{user_base_label}:Technology {{name: 'Kubernetes', type: 'technology'}}) + CREATE (p:{user_base_label}:Technology {{name: 'PostgreSQL', type: 'technology'}}) + RETURN d.name, k.name, p.name + """ + await graph_service.neo4j.execute_query(create_query) + + yield ["Docker", "Kubernetes", "PostgreSQL"] + + # Cleanup after test + await graph_service.neo4j.execute_query(cleanup_query) + + +# ============================================================================ +# Unit Tests - Entity Mention Detection +# ============================================================================ + +class TestFindEntityMentions: + """Test finding entity mentions in content.""" + + def test_find_single_mention(self): + """Test finding a single entity mention.""" + content = "Docker is a containerization platform." + entities = [ + {"name": "Docker", "type": "technology"} + ] + + found = find_entity_mentions(content, entities) + + assert len(found) == 1 + assert found[0]["name"] == "Docker" + assert found[0]["mentions"] == 1 + + def test_find_multiple_mentions(self): + """Test finding multiple mentions of same entity.""" + content = "Docker containers run on Docker Engine.
