GitHub Workflows Audit Report

Overview

This document provides a comprehensive audit of all GitHub Actions workflows in the Bridge project, detailing what each workflow does and identifying gaps in integration testing.

Current Workflows

1. bridge-server.yml - Bridge Server CI

Purpose: Build and test the bridge server component What it does:

  • ✅ Type checking
  • ✅ Linting
  • ✅ Building server
  • ✅ Docker image creation
  • ❌ No unit tests (skipped)
  • ❌ No integration tests

Components tested: Bridge server only Integration coverage: None

2. integration-tests.yml - E2E Integration Tests

Purpose: Test integration between components What it does:

  • ✅ Sets up PostgreSQL, NATS, Consul
  • ✅ Runs database migrations
  • ✅ Starts bridge server
  • ✅ Tests basic API endpoints
  • ✅ Tests service connectivity
  • ⚠️ Uses mock MPC tools (not real)
  • ❌ No Vault (KMS) integration
  • ❌ No Casdoor (ID) integration

Components tested: Bridge, PostgreSQL, NATS, Consul, Mock MPC Integration coverage: Partial (missing ID and KMS)

3. mpc-e2e-tests.yml - MPC End-to-End Tests

Purpose: Test MPC network setup and operations What it does:

  • ✅ Sets up NATS and Consul
  • ✅ Creates MPC configuration
  • ✅ Starts 3 MPC nodes
  • ✅ Tests node connectivity
  • ⚠️ Uses mock MPC binaries
  • ❌ No real signature generation
  • ❌ No KMS integration
  • ❌ No ID integration

Components tested: Mock MPC, NATS, Consul Integration coverage: Limited (mock only)

4. build-and-push.yml - Build and Push Images

Purpose: Build Docker images and push to registry What it does:

  • ✅ Builds bridge-server image
  • ✅ Builds bridge-ui image
  • ✅ Multi-platform support (amd64, arm64)
  • ✅ Pushes to GitHub Container Registry
  • ❌ No testing before build

Components tested: None (build only) Integration coverage: None

5. server.yml - Server Deployment

Purpose: Deploy bridge server to Kubernetes What it does:

  • ✅ Builds Docker image
  • ✅ Pushes to registry
  • ✅ Deploys to Kubernetes
  • ❌ No pre-deployment tests
  • ❌ No post-deployment verification

Components tested: None (deployment only) Integration coverage: None

6. mpc-nodes.yml [DEPRECATED]

Purpose: Previously built MPC node images Status: Deprecated - directory removed

7. mpc-tests.yml [DEPRECATED]

Purpose: Previously tested MPC service Status: Deprecated - directory removed

Missing Integration Testing

1. Identity Service (Casdoor/Lux ID)

  • Not tested in any workflow
  • No authentication flow testing
  • No OAuth/OIDC integration tests
  • No user management tests

2. Key Management Service (Vault)

  • Not included in any workflow
  • No key storage/retrieval tests
  • No encryption/decryption tests
  • No MPC key management tests

3. Full System Integration

No workflow tests the complete flow:

User Auth (Casdoor) → Key Retrieval (Vault) → MPC Signing → Bridge Operation

4. Cross-Chain Operations

  • No actual blockchain interaction tests
  • No token minting/burning tests
  • No cross-chain transfer simulations

5. Real MPC Operations

  • All workflows use mock MPC tools
  • No real threshold signature tests
  • No distributed key generation tests

6. Performance Testing

  • No load testing
  • No stress testing
  • No performance benchmarks

New Workflow Added

full-integration-tests.yml - Comprehensive Integration Testing

Purpose: Test all components working together What it does:

  • ✅ Sets up ALL services (PostgreSQL, NATS, Consul, Vault, Redis, Casdoor)
  • ✅ Initializes Vault with test keys
  • ✅ Starts Casdoor for authentication
  • ✅ Configures MPC network with KMS integration
  • ✅ Tests ID → KMS → MPC → Bridge flow
  • ✅ Tests all component health checks
  • ✅ Runs existing test scripts
  • ✅ Includes performance and security audit jobs

Components tested: All components Integration coverage: Full system integration

Recommendations

1. Enable Real MPC Testing

  • Provide access to MPC repository
  • Build real MPC binaries in CI
  • Test actual threshold signatures

2. Add Component-Specific Tests

  • Create vault-integration-tests.yml
  • Create casdoor-integration-tests.yml
  • Create mpc-real-tests.yml

3. Implement Mock Blockchain Testing

  • Use Hardhat/Ganache for local chains
  • Test actual bridge operations
  • Verify token transfers

4. Add Monitoring Tests

  • Prometheus metrics validation
  • Grafana dashboard checks
  • Alert testing

5. Security Testing

  • OWASP dependency checks
  • Container scanning
  • Penetration testing simulations

6. Performance Baselines

  • Establish performance benchmarks
  • Track regression over time
  • Load test critical paths

Workflow Execution Matrix

Workflow Build Test Integration Deploy Security
bridge-server.yml ✅ ⚠️ ❌ ❌ ❌
integration-tests.yml ❌ ✅ ⚠️ ❌ ✅
mpc-e2e-tests.yml ❌ ✅ ⚠️ ❌ ❌
build-and-push.yml ✅ ❌ ❌ ❌ ❌
server.yml ✅ ❌ ❌ ✅ ❌
full-integration-tests.yml ✅ ✅ ✅ ❌ ✅

Summary

Current workflows provide basic CI/CD but lack comprehensive integration testing. The new full-integration-tests.yml workflow addresses these gaps by:

  1. Testing all components together (ID, KMS, MPC, Bridge)
  2. Validating service interactions
  3. Running end-to-end scenarios
  4. Including performance and security testing

To achieve full coverage, the project needs:

  • Real MPC binary access
  • Mock blockchain environments
  • More comprehensive test scripts
  • Performance baselines
  • Security scanning integration
