From 42c257c3def0dc1b6d75783bcde3d0761d82f526 Mon Sep 17 00:00:00 2001 From: Daniel Chalef <131175+danielchalef@users.noreply.github.com> Date: Mon, 25 Aug 2025 20:43:50 -0700 Subject: [PATCH] feat: Add comprehensive Neo4j integration testing to GitHub Actions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Neo4j Service Integration ### ๐Ÿ—„๏ธ Database Service Container - Added Neo4j 5.26 service container with proper configuration - **Health checks**: Cypher-shell connectivity validation with 30s startup period - **Memory optimization**: 256-512MB heap, 256MB pagecache for CI environment - **APOC plugin**: Included for enhanced graph operations - **Ports**: 7687 (Bolt), 7474 (HTTP) exposed for testing ### ๐Ÿงช Integration Test Suite - **Neo4j Connection Test**: Direct driver connectivity validation - **HTTP Integration Tests**: Full MCP server testing via HTTP endpoint - **MCP SDK Integration Tests**: Official MCP Python SDK validation - **Server Startup Test**: End-to-end server initialization with database ### โš™๏ธ Test Environment Configuration - **Environment Variables**: Proper Neo4j credentials and OpenAI test keys - **Timeouts**: Robust 120s timeout for integration tests, 30s for startup - **Wait Conditions**: Smart Neo4j readiness detection with retry logic - **Error Handling**: Graceful failure reporting for timeout/connection issues ### ๐Ÿ”ง Test Infrastructure Improvements - **Updated Integration Tests**: Fixed server command from `graphiti_mcp_server.py` โ†’ `main.py` - **Dependency Management**: Added neo4j Python driver for connection testing - **Multi-Stage Validation**: Connection โ†’ Integration โ†’ Server startup progression - **Comprehensive Coverage**: Unit + Integration + End-to-end testing ### ๐Ÿ“Š Testing Workflow Enhancements ```yaml services: neo4j: image: neo4j:5.26 env: NEO4J_AUTH: neo4j/testpassword options: --health-cmd "cypher-shell ..." ``` ### ๐ŸŽฏ Benefits - **Complete Testing**: Database integration validation in CI - **Real Environment**: Actual Neo4j instance for realistic testing - **Fail-Fast**: Early detection of database connectivity issues - **Production Parity**: CI environment matches deployment requirements - **Integration Confidence**: Full MCP server stack validation The workflow now provides comprehensive testing from syntax validation through full database integration, ensuring the MCP server works correctly with Neo4j in production-like conditions. ๐Ÿค– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .github/workflows/mcp-server-tests.yml | 121 ++++++++++++++++++++++- mcp_server/tests/test_mcp_integration.py | 2 +- 2 files changed, 121 insertions(+), 2 deletions(-) diff --git a/.github/workflows/mcp-server-tests.yml b/.github/workflows/mcp-server-tests.yml index 8e80082a..a2d2fb7e 100644 --- a/.github/workflows/mcp-server-tests.yml +++ b/.github/workflows/mcp-server-tests.yml @@ -14,6 +14,26 @@ jobs: permissions: contents: read id-token: write + + services: + neo4j: + image: neo4j:5.26 + env: + NEO4J_AUTH: neo4j/testpassword + NEO4J_PLUGINS: '["apoc"]' + NEO4J_dbms_memory_heap_initial__size: 256m + NEO4J_dbms_memory_heap_max__size: 512m + NEO4J_dbms_memory_pagecache_size: 256m + ports: + - 7687:7687 + - 7474:7474 + options: >- + --health-cmd "cypher-shell -u neo4j -p testpassword 'RETURN 1'" + --health-interval 10s + --health-timeout 5s + --health-retries 10 + --health-start-period 30s + steps: - name: Checkout repository uses: actions/checkout@v4 @@ -95,4 +115,103 @@ jobs: print('โœ… Graphiti Core available') except ImportError: print('โš ๏ธ Graphiti Core not available (may be expected in CI)') - " \ No newline at end of file + " + + - name: Wait for Neo4j to be ready + run: | + echo "๐Ÿ”„ Waiting for Neo4j to be ready..." + max_attempts=30 + attempt=1 + while [ $attempt -le $max_attempts ];
