Terraphim AI Testing Infrastructure Improvement Plan

Created: Tue Nov 11 2025 Status: ACTIVE Priority: HIGH

Executive Summary

This plan addresses critical testing infrastructure issues identified in the test and benchmark report. The focus is on creating a robust, modular testing framework that can execute all tests and benchmarks reliably within reasonable timeframes.

Phase 1: Immediate Fixes (Critical Issues)

1.1 Fix Multi-Agent Benchmark Configuration

Issue: test-utils feature flag missing from benchmark execution Root Cause: run-benchmarks.sh doesn't include required feature flags Status: ⏳ PENDING Solution:

  • Update run-benchmarks.sh line 46 to include --features test-utils
  • Modify cargo bench command: cargo bench --features test-utils --bench agent_operations

1.2 Create Modular Test Execution Strategy

Issue: Full test suite compilation exceeds timeout limits Root Cause: MCP server and heavy dependencies slow down compilation Status: ⏳ PENDING Solution:

  • Create separate test categories: core-tests, integration-tests, mcp-tests
  • Implement --category flag in run_all_tests.sh
  • Exclude MCP server from core test runs

Phase 2: Enhanced Test Infrastructure

2.1 Create Tiered Test Scripts

New Scripts to Create:

  • scripts/run_core_tests.sh - Fast unit tests only
  • scripts/run_integration_tests.sh - Service-dependent tests
  • scripts/run_mcp_tests.sh - MCP-specific tests
  • scripts/run_performance_tests.sh - All benchmarks with proper flags

2.2 Optimize Test Execution

Improvements:

  • Add parallel test execution using --test-threads optimization
  • Implement test result caching
  • Add timeout management per test category
  • Create test dependency graph for optimal execution order

Phase 3: Benchmark Infrastructure Fixes

3.1 Fix All Benchmark Configurations

Actions:

  • Update run-benchmarks.sh to handle feature flags per crate
  • Add benchmark timeout management
  • Implement fallback for missing dependencies
  • Create benchmark-specific Cargo.toml profiles

3.2 Add Missing Benchmark Features

Enhancements:

  • Add memory usage benchmarks for persistence
  • Create performance regression detection
  • Implement automated baseline comparison
  • Add benchmark result archiving

Phase 4: CI/CD Integration

4.1 Implement Parallel CI Pipeline

Strategy:

  • Split CI into stages: unit, integration, performance
  • Use matrix builds for different test categories
  • Add test result aggregation
  • Implement performance regression alerts

4.2 Add Test Coverage Reporting

Implementation:

  • Install cargo-tarpaulin for coverage
  • Generate coverage reports per crate
  • Create coverage thresholds
  • Add coverage badges to README

Phase 5: Advanced Testing Features

5.1 Performance Baselines

Create:

  • Define performance thresholds for all benchmarks
  • Implement automated performance regression detection
  • Add performance trend analysis
  • Create performance dashboard

5.2 Integration Test Environment

Setup:

  • Create dedicated test environment configuration
  • Implement service health checks
  • Add test data fixtures
  • Create test isolation mechanisms

Detailed Implementation Steps

Step 1: Fix Benchmark Script (Immediate)

File: scripts/run-benchmarks.sh Line: 46 Change:

FROM: if cargo bench --bench agent_operations > "${CARGO_BENCH_OUTPUT}" 2>&1; then
TO:   if cargo bench --features test-utils --bench agent_operations > "${CARGO_BENCH_OUTPUT}" 2>&1; then

Step 2: Create Core Test Script

New File: scripts/run_core_tests.sh Focus: terraphim_types, terraphim_automata, terraphim_persistence Exclude: MCP server, integration tests Timeout: 5 minutes

Step 3: Update Main Test Script

File: scripts/run_all_tests.sh Changes:

  • Add --category flag
  • Implement conditional test execution
  • Add better timeout management
  • Separate MCP testing

Step 4: Add Performance Regression Detection

New File: scripts/check_performance_regression.sh Functionality:

  • Compare current benchmarks with baselines
  • Alert on performance degradation > 10%
  • Generate performance trend reports

Step 5: Implement Test Coverage

Add to CI pipeline:

cargo tarpaulin --workspace --out Html --output-dir coverage/
  • Generate coverage badges
  • Set minimum coverage thresholds

Expected Outcomes

Test Execution Time Improvements

  • Core Tests: < 2 minutes (vs current timeout)
  • Integration Tests: < 10 minutes
  • Full Suite: < 15 minutes (vs current failure)
  • Benchmarks: Complete execution with all features

Quality Improvements

  • Test Coverage: > 80% across all crates
  • Performance Regression: Automated detection
  • CI Pipeline: Parallel execution with clear stages
  • Benchmark Reliability: Consistent execution with proper feature flags

Monitoring and Reporting

  • Real-time Test Status: Dashboard with test progress
  • Performance Trends: Historical benchmark data
  • Coverage Reports: Per-crate coverage metrics
  • Regression Alerts: Automated notifications
