Implement Testing Framework and CI Pipeline

[vivekpal1]

Our project currently lacks adequate test coverage, which puts reliability at risk as we scale. A robust testing framework would help catch bugs earlier, ensure stability across changes, and maintain consistent performance.

Proposed Implementation

Unit Testing

• Create unit tests for all core components (processors, publishers, network layers)
• Focus on edge cases and failure modes
• Implement mocking framework for external dependencies

Integration Testing

• Develop end-to-end tests covering complete data flows
• Test data ingestion → processing → storage → retrieval
• Verify correct handling of different Solana account and transaction types

Simulation Testing

• Build network simulation framework to test under various conditions:
  • High latency connections
  • Packet loss scenarios
  • Node failures and recovery
  • Network partitions

CI Pipeline Enhancements

• Implement GitHub Actions workflow with the following stages:
  • Build verification
  • Unit and integration test runs
  • Performance benchmarking against baseline metrics
  • Code coverage reporting (aim for >80%)

Advanced Testing Techniques

• Add property-based testing for state transitions using frameworks like proptest
• Create reproducible test scenarios for common failure cases
• Implement chaos testing for network resilience

Success Criteria

• All critical components have >80% test coverage
• CI pipeline runs automatically on PRs and main branch
• Performance regression tests detect slowdowns before deployment
• Simulated network failures consistently trigger correct recovery procedures

Timeline

Estimated 3 weeks for initial implementation, with ongoing improvements thereafter.
