# Chartbrew Backend Testing Progress

## Overview
This document tracks the progress of implementing comprehensive testing for the Chartbrew backend API. The goal is to ensure all user-related functionality, connection management, datasets, charts, and other core features are thoroughly tested.

## Testing Stack
- **Vitest**: Test runner with watch mode and coverage reporting
- **Supertest**: HTTP assertion library for testing Express APIs  
- **Testcontainers**: Isolated database instances per test run (MySQL/PostgreSQL)
- **@faker-js/faker**: Test data generation
- **Umzug**: Database migrations in test environment
- **SQLite3**: Fallback database for environments without Docker

## GitHub Actions Workflows

### 1. Basic Test Workflow (`test.yml`)
- **Trigger**: Push/PR to main/develop branches
- **Node.js**: Current CI uses Node.js 22.23.4 with MySQL/PostgreSQL. The Node 18.x/20.x matrix is no longer used.
- **Features**: ESLint, Tests, Coverage reporting
- **Fallback**: SQLite testing when containers fail

### 2. Comprehensive CI (`ci.yml`)
- **Trigger**: Push/PR to any branch
- **Features**: Security audit, Code quality, Multi-database testing, Build verification
- **Jobs**: Security, Lint, Backend tests (MySQL), Backend tests (PostgreSQL), Frontend tests, Build verification

### 3. Integration Tests (`integration.yml`)
- **Trigger**: Daily schedule + manual dispatch
- **Features**: Performance testing, Container health checks, Extended integration tests
- **Duration**: Longer-running tests for comprehensive validation

### 4. Badge Updates (`badges.yml`)
- **Trigger**: After CI completion
- **Features**: README badge updates, Coverage reporting

## Next Steps

1. **Implement User API Tests** - Start with signup/login endpoints
2. **Add Connection Management Tests** - CRUD operations for database connections
3. **Build Chart/Dataset Testing** - Core functionality testing
4. **Expand Coverage** - Aim for 70% overall coverage
5. **Performance Testing** - Add load testing with Artillery or k6
6. **Security Testing** - Implement comprehensive security test suite

## Notes

- **Docker Integration**: Fully working with MySQL containers, PostgreSQL support ready
- **Migration Handling**: Special handling for problematic migrations in test environment
- **Container Optimization**: Single shared container per test run for performance
- **Fallback Strategy**: SQLite fallback ensures tests work in any environment
- **CI/CD Ready**: Complete GitHub Actions setup ready for production use
- **ESLint Integration**: Test-specific rules allow console.log and development patterns

## Issues & Limitations

- **PostgreSQL SSL**: May need SSL configuration tweaks for some environments
- **Container Dependencies**: Requires Docker for full feature testing (SQLite fallback available)
- **Migration Complexity**: Some migrations need special handling for test environments
- **Performance**: Container startup adds ~15s to test execution (acceptable for CI)

## Resources

- **Coverage Reports**: Available at `server/coverage/index.html` after running `npm run test:coverage`
- **Local CI Testing**: Use `./scripts/test-ci-locally.sh` to test before pushing
- **Container Logs**: Available via Docker commands for debugging
- **Test Documentation**: This file serves as the primary testing documentation
